C4 Chassis Stiffeners from Killebrew

[Bob Eyres]

Here's an article mentioning Gordon's chassis stiffener kit:

Has anyone tried this on a ZR-1? Effective? Results?
Sorry, if this has already been discussed elsewhere.

Forum member -=Jeff=- is running them, I believe. He seems to be happy with them.

I installed a convertible x-brace and am very happy with the improvement in overall feel of the chassis, and reduction in shakes and rattles. I am curious to compare the difference but not willing to drop $500 to do so.

[Bob Eyres]

I wonder how it would do with both? Or are the attachments in the same place?

Now let's see, if you used these braces, plus a convertible brace, plus one of those stiffeners for the Targa bar to windshield frame, plus a four point roll cage, that sucka would be damn rigid.

But you'd probably have added an extra 100 lbs. of unwanted weight.

Very interested to hear your positive result. The rules I race under would allow this addition, as I can use any part on any C4. Any chance you have pics, especially near the headers?

Best,

Hey Jeff, I don't have any pictures -- but I may have some time in the next few days to jack the car up to take a few pics for you.

Next time you're under it that would be awesome. I'll be looking forward!

The front attachments share the same pre-threaded holes. I think it might be possible to "stack" the two devices, but I can't be sure.

The rear attachments are in different locations, I think. The x-brace goes to the recess just inboard of the jacking points in the rear. The above braces I think attach to the dogbone mount bracket.

What do people w headers do? I know =Jeff= has 2" headers and Gordon's bracing run along the rocker panel. They're designed to tie front and back of the chassis.

I have Jeal headers, I have about 1/8" clearance between the driver's side ball joint clamp and the x-brace.

I have them... I think they work as Advertised. I actually noticed an improvement when I left the place I had them installed at.

my car also would creak/twist pulling n my driveway, it no longer does it.

The braces were installed in 2010 and I have been happy with them since. I have adjusted them twice mainly because they were the 1st prototypes that were manufactured by vette2vette.. there have been improvements on the bars as far as getting a wrench on to tighten them ( something mine don't have)

Overall I would buy them again for any C4..
