New C4 Frame Braces [Archive] - ZR-1 Net Registry Forums

I might have your answer..

Currently on my Car are a set of frame brace to help give the C4 a solid frame feel like the C5. These will bolt in any post-86 (uses front X brace bolt points), no drilling required, although there might be an extra hole in the brace that would require one hole to be drilled but would be optional. These braces can be left on while removing exhaust ETC, it is not a cross brace of any type.. The Brace was designed by Gordon Killebrew..

These braces are NOT lower then my exhaust. they are similar to F-body Sub frame connectors (in mounting) and are not X-Braces

So far I have driven 100 miles with the top on but the car is definitely more solid then it was prior.

Need to drive with the top off to see how well it is

in the picture below the car is dirty from rain..

you can see the head of one bolt here on the left and the rod (in black) running length of car..

Hey Jeff, so what are your driving impressions of these braces?
Do they make life on the street a bit tougher? What about if you need to jack up the car, or put her up on j-stands?

:happy1:

Believe it or not, i have not had time to drive it since I drove it home in the rain after the install, I was out most of last week and been busy since i have been home. I WILL drive it Thursday Friday and Saturday so I will get you a better feel for them then

I believe I should be able to jack the car still, but having a kwiklift I don't use stand much. but I have yet to test it.. Soon, I hope

I an trying.. I have been busy with work ( out of town last week) spent time with kids on Saturday and then family stuff on Sunday.. last 2 days called for rain, so i did not drive my vette (although no rain so far)

gordon showed me these at carlisle last year and glad they are coming out for sale!

read Dave M.'s book (corvette from the inside)

c4 in early design stage wasn't going to have a targa, it was a "design change" that gave the c4 chassis a "flex point" that leads to loss of chassis stiffness with the top off (and not all that great with it in! vice the c5/6!!!)

this mod should "shore up the design flaw" just like beam plate and other little tweak.

for sure I run with the top off lots (but not much without my targa truss!)

but even with the top in this should stiffen up the car to help the suspension do a better job. if you look at the c5/6 "tube" in lieu of the c beam and the improvements made the frame itself, you can see where they engineered out the flex points in the c4 and made the c5 many times stiffer

c6 is stiffer still. when you can reduce the chassis flex, you can really optimize the handling, reduce spring rates, gain consistency, plant the HP, all kinds of good benefits. Gordon and I talked about this for quite a bit but like many things, I promsied not to say much until he got his patent and decided to market it. sure glad he did!! I've been dying to see this and try it out. my bet (not for sure obviously) is that this is another "simple mod" that will minimally increase weight, but really help stiffen the car.

I often thought of some "weld in" stiffeners that would reduce the "hinge point" which is just ahead of the front of the door where the chassis bends in, but there isn't a whole bunch of room there

this seems like a very logical and well thought out design. rods in "tension" are very light, and should help stiffen things up.

come on vette2vett price those suckers out!

looking forward to more reports and thanks very much for posting up the pics. nice work.:happy1::dancing:cheers:

He IS willing and interested in a Group Purchase. BEFORE YOU ASK AGAIN

I WILL GET PRICING TOMORROW.. When I see him, he will also give me group pricing as well.

Now, I drove the car with the roof out, yes it is a stiffer more solid ride then without them. I still need to drive it more to determine how much of a difference it is, but there is a difference. Car is definitely tighter.

:happy1: I too am waiting on an answer to Toms question. I also agree that price point is pretty brutal.

:happy1: I agree on the pricing as proposed that is a bit steep; but then when I looked at new B-K harness bars I had the same reaction. They are in the $600.00 range new.

What was that old saying? Speed costs? So you want to go quickly thru the twisties? How much do you have to spend, that's how quickly you can go. :neutral:

maybe we can figure out how to make and install a torque tunnel in our C4's........:o.....I'll go take my meds now.

So are you pretending you did not receive the information; or, are you only pretending to share the information here?

All kidding aside, there isn't much on the vette2vette web page. With my targa top off, my otherwise solid Z suddenly feels and sounds like a rattle trap. Unless I'm imagining things, with my eyes on the C4 A-pillar, my hands on the wheel and my *** on the seat it looks and feels like the front end is moving independently of the seat I'm sitting on. If I goose the accelerator in first or second gear, I can feel the steering wheel pull. With the top in place, the car is tight and does not rattle or pull.

Jeff, did you experience any of what I'm describing with the top off before the frame braces were installed? Do the frame braces only improve the situation or do they make the car feel like it did with the top in place?

Any information would be appreciated.

Scott,

My first C4 was a 84 4+7 manual with Z51 suspension. With the top off, over the railroad, I could see the steering wheel move laterally by about half an inch!
GM upgraded "K" member around 87 (I think). That reduced lateral shift by 1/8 to 1/4" - depends how bad the undulation is.
My 91 Z, I had "Corvette Master" in Casselberry, FL, take an "X" member (sort of a c channel) for convertibles and stitch weld a plate effectively creating a box member. Front of coupe has a bolt hole already (I think). For the rear, Robbie had to drop a bolt into a plate and weld the plate to the bird cage. This worked real good but added some weight.

That's what R-D cross brace is, stronger then a stock converitble cross brace.

http://www.r-dracing.com/CROSS-FRAME.htm

I have this, it work VERY VERY well. It just hangs WAY to low to the ground. My car is lowered 1-1.5 and the cross brace can not be used for street driving.

So the cross brace is only $435 and the new frame braces will be $795. Any clearance issues with the cross brace on stock ride height cars? How much does it weigh?

Yes, car was like a noodle before with the top off, it is better witht he brace, but I still have not been able to adjust it. As for Jacking, yes I forgot to do that.. will get to it this week,

Jason has been at Bloomington Gold this weekend, I am home afetr 3 days of the show and heat I needed a break.

I have GP pricing, which is good, but it is tiered depending on amount of people, I am going to put a webpage together for the pricing and try to get a picture of the demo he had a chunk of frame..

But I think the discount will be good if we get enough interest. just a couple more days..

It looks to me that we all have to declare our intentions in order to see what our price will be.....so I'm "IN" for counting purposes. My guess is we are in the "10 items" range unless a lot of people are lurking?

Sorry I still need to see a bit more info on what the parts kit looks like and I have to go look at my frame to figure out my jacking and jack stand issues.

Just so I'm clear on the theory. These help stiffen the frame flex that has it's hinge point near the A-pillar, right? That would be mostly deflection in the vertical plane for chassis movement? The way I see it you still need to consider adding a harness bar to add resistance to diagonal twisting, anyone? Therefore, the total investment would be the B-K bar + these frame braces ( $1300.00 round #'s ) for a reasonable cure short of installing a cage or something like a back bone structure....sorry I'm thinking out loud :redface:....

I owe you this still, I am sorry I will get to it, I can't today though with the heavy rain right now, but maybe pictures from underneath will help.

you might need the diagonal stiffener, not sure quite yet.. still a few things for me to adjust, with my vette on the kwiklift, and having the right tools now, I will try to adjust it as well, but due to it being lowered there is not much room for the wrench..

Wouldn't the cross frame brace be the equivalent of the harness bar and the frame braces?

I wish I knew the answer to that Q!:redface: In theory ( who says I understand the theory!:sign10: ) I would guess that the GM engineers used the vert's X brace to make up for the lack of a roof panel? I know that addition makes it nearly impossible to get to the fuel filter, or so I've been told. Kevin, ( Polo1 ) says his works and I guess I should have used the link to look at the brace he uses.

My car is not lowered so I am guessing I could have a lot of options for stiffening the frame. Another thought just crossed my mind. On my 72 the frame was spot welded, and a common trick back in those days was to seam weld it. I had it done on my car and I was never unhappy with the rigidity of the chassis on the street....but that was a different chassis design to a C4, and the roof panels were not structural.:icon_scra

uses the bottom bolt of the trailing arm bracket.. so it is bolt, Frame bracket, then trailing bracket, then body

I think what I would do then is remove the strut bracket (trailing arm bracket) removing the three bolts into the chassis. Remove the two struts (first), weld the C4 Frame Brace solidly to the strut bracket (trailing arm bracket).

Re-install the strut bracket/C4 Frame Brace using the three bolts that held it in the first place ;)

Then re-install the struts :cheers:

Yes I think he was going to add a lower bolt too, but that required drilling..

I might add the lower bolt that he and I talked of..

So did you order a set?

Hi Jeff,

I finally got around to try to install this system today. I got the front bracket on and found I do have to drill a hole for the rear bracket (he must have added that after the prototype; I just bought mine last year) so drill is charging. How do you jack up the car (I think you have a kwiklift) and can the factory jack still be used if I get a flat? It seems the bar will be in the way and the instruction indicate using a ramp or lift to install so I'm not sure yet if I can actually put the bar on after I get the brackets installed. As I said it only appears this way and I have not gotten that far yet to test fit and ensure I can still lift the car at the original point below the mirrors with my floor jack and special adapter I have been using all these years.

Thanks,

We drilled a hole in mine and I'd recommend doing it in yours

Absolutely love the kit and it's made a huge difference. Look forward to hearing your impression Craig!

Hey Craig,

Not sure if the extra hole is needed, Mine don't have that like you said.

As for jacking, I use the mounting points where the bar connect to raise and lower the car with my floor jack. Those seem to be solid enough

Hey Jeff,
Thanks for confirming about using those mounts and I guess it really ties them in well enough as I read and it will lift evenly even if front or rear is picked up.

Thanks David. I will always do more than less and I don't like extra parts; I imagine it was an improvement that was added and it makes sense for strength. I did not finish the install and will get some flat washers first.

Can one of you guys get a picture of the hole and location for me?
Thanks

Here are some photos Jeff:

I can see that the emergency brake cable is going to be an issue once the bar is installed with the large bolt and nut. I'm curious to know how you folks installed with that cable in the way. I decided to get flat washers that it did not come with before installing the bar and heim joints. I also want to see if there is a way to get covers for the joints, but maybe not. The hardware store here did not have flat washers that big so I know another place on the way home tomorrow. :handshak:

You're very welcome. Do you remember what was done about the emergency brake cable being in the way on the driver's side? I'll check and someone mentioned the same problem, but don't remember what they did to resolve it.

mine was around the outside but tight..

I think now it is sitting just below the Heim...

How does this kit help torsional twisting, like when a front tire is lifted the car will twist like if you were tightening a bolt. I always thought the x brace would help correct this, but will not help bending for and aft of the car, which these mentioned will help with.

My never cars seem more solid and stiff chassis compared to the Z, wondering which of the two brace types would help with the flexing. Does anyone know what type of flexing is more common? The fore-aft bending, or the torsional/twisting, of the chassis?

Well, I completed the install yesterday and pleased with the results despite not driving it yet. I should be getting temp plates next weekend to drive the car and put the headers back on so I can post some opinions then. What I like about it is there is no doubt that it stiffens up the chassis and flex as stated when jacking the car and seeing how the measurements don't change with roof off and jacking as well as how you can lift the front or rear and the entire car lifts (door can open and close either way). I have to imagine it helps when driving too and they guys that designed it are quite intelligent and respected in the C4 community. What do I not like? The added weight to my car after trying to take off stuff all these years to lighten the car. No issues to get the brake cable on the side after install, but will watch it to be sure it does not chafe the cable in time.

Old thread, but how has these braces held up and are they the same one but updated that vette2vette came out with recently. How has the brake line chaffing held up?

I have had my Vette2Vette No-Flex installed for about 4 years and no issues. Two years ago when my car was with Marc I asked him to check just in case it needed adjustment but he said it was good to go. I think it makes a big difference and am pleased with it. No issues with brake lines.

Yes, no issues. We did the install during one of our Wazoo maintenance days. Scrrem had one before I did mine so he got to supervise.

Awesome product and I highly recommended it. I transferred it from my 90 to my 95 when I sold it and still love it for the overall way that it stiffens up the chassis. I think what I love about it most is for lifting the car. It?s so easy with a floor jack or Quickjack. The helm mounting joint bracket is perfect for either way. It does not matter if you pick up the front or back because the entire side will lift as one;
It is that strong and solid. No issues at all about brake cable. [emoji1303]🤙🏼1462914630

After lots of research on how to adj the bars. Found most info. on CF Post # 55 talks about this method

https://www.corvetteforum.com/forums/c4-general-discussion/3700009-vette2vette-no-flex-chassis-stiffening-bars-don-t-work-3.html

Method 1. Adjust by the number of threads counted at each end. It was found that you could have a slight difference in the distance between the brackets from side to side due to GM + or - tolerances when building the car. This can give an unequal tension from side to side.

Method 2. Use the same Toque value on each bar so you have the same tension side to side.

I ordered a set from him just few weeks ago, and he was very helpful and answered all my questions very promptly and i got the system shipped to me here in Iceland very quickly.

This is the email i used to contact him. Parts@vette2vette.com

I haven't been able to test the system very much, just been able to drive around the block since it's still winter here, but i could definitely feel a big difference just going up the driveway at an angle the car twisted a lot less.

Jason, called me this morning. Of course got voicemail, who answers unknown callers anymore, dang spammers, called him back, got HIS VM. Told him I would call him in the morning. I have an additional part I hope he might can help me with too. So all should be good. I am sure I will be asking some install questions, but if anyone has any installation pics feel free to post or email me a corvette95@gmail.com Thanks!

Safety Avisory

I installed one late last summer. I am very pleased. Yes as some noted it does stiffen the ride. Observe very careful with the front bracket installation your brake line bundle on the driver side and fuel line on the passenger side. There is the very dangerous possibility of a rub on the bracket edge. The fuel line i flexed and bent for clearance. The brake lines I isolated with thick pieces of plastic drilled for zip ties. This personal attention to detail sincerely avoided a catastrophe.
