ZO7

[rhipsher]

Was there a corvette model Zo7 back in the 90's? The reason I ask is I was having a friendly conversation on another site when this guy butts in and say that a ZR-1 was nothing more than a regular corvette with a different engine in it and that there are tons of places that can work on an LT-5. He said the Zo7 was a much better handling car than a Z was anyway and on and on and on. So I responded by saying- And like most people that shoot their mouths off! They lack the facts. #1 There is a bit more to a Z than just the engine. #2 No! Not just any shop can work on an Lt-5. #3 I've never heard of a Zo7. And #4 If you really cared to know the differences between diet coke and Jolt Cola then all you have to do is google it. But from what I've gathered it wasn't a very popular option. So if you guys know anything about it lets hear.

Z07 was the name replacement for the Z51 cars for several years. Z51 reappeared in 96 after disappearing in 91.

And on a autoX course, a stock Z07 will clock a stock ZR-1.

Wouldn't be the first time I've been banned for speaking the truth.

I'm thinking we stone Jeff to death at BG with old LT-5 parts.....its the only way to rectify this issue!

Lets put it to a vote!:hello:

[USAFPILOT]

I think the ZO7 has much stiffer springs than stock or the ZR and came with the J55 brakes. I dont know why the ZR1 didn't get the stiffer springs. But did a ZO7 have the adjustable suspension?

[GOLDCYLON]

Somebody did a huge write up on the differences. Seen the write up will try to find it again. GC

Just don't stone him with any big parts like a thermostat housing, he has to much knowledge in his head of take him out :dancing

Jeff speaks the truth. I used to have a 94 with the Z07 option, it was one well balanced car. Certainly not a match for the ZR-1 in acceleration but it was definitely a better handling car out of the box. From what I recall the package included the 13in front brakes, 30mm front bar, stiffer springs, 9.5in wheels with 275mm tires on all four corners and a few other changes. Mine had the FX3, not sure if they all did.

They all did. Z07 was basically the Z51 stuff coupled with FX3. I imagine the ZR-1 was not so equipped because it was more of a GT car. While I'm sure it handled great, the Z51 was pretty rough riding. I don't know how much the FX3 helped, but my '87 Z51 was pretty uncivilized on anything but smooth pavement.

Didn't it also have a closer steering ratio?

The Z51 had a closer ratio rack. As far as I know the Z07 did as well. I believe it had all the Z51 equipment including the power steering cooler, oil cooler, rack, and the suspension stuff.

What is interesting is when the FX3 option came out in 89, it was coupled with the Z51 option. In 90, you could order them separate. In 91, the Z07 package was the FX3 with the all of the Z51 goodies. Probably why they changed the name. Then in 96 you had the new adjustable ride and could not combine the package and then Z51 reappeared.

GM does some bizarre crap.

Tattle Tales.

[ZR1Vette]

Damn...with the spring rates on the Z07 that must have been some spine compressing ride

[USAFPILOT]

Its funny you learn all of this afterwards...I was always under the impression that a ZR1 was fully loaded...but in fact it is missing the performance springs, and steering rack. So strange, but easy to add if you were so inclined. Personally, I like the way my ZR1 handles just fine.

I know that a cars performance is measured in many aspects of performance.
However, owning several corvettes over the past 10 years and 2 C4s now and a 1 C5, The ZR-1 is the best.

When you step on the pedal and waken the beast, it is just an awesome feeling. For me personally, just the straight line nasty acceleration is worth it and of course hearing the LT-5 singing in the high rpm ranges.

I typically mind my business, but I've had a few Porsches for lunch and they are tasty.

[rhipsher]

I can't quite pin point what it is about this car that can turn a man into a finatic over night. But yes it accelerates like a bomb going off. And handles pretty good. And still looks mean as hell going down the road weather your in back of it or in front of it. And people either love them or hate them. The ones that love them won't shut up about them. (That would be us) And the ones that hate them always try to minimize them and their existence.

[WB9MCW]

Well I hear that Pete has Z08 on hiz ZR-1 now!

You know people can talk about turbo this turbo that all day long. I've lived in alot of rich areas, a good many of them in South Florida. The bottom line is that usually you don't come up against super fast cars on the street. When I was younger, I would put away cars with my LT1 left and right. Now 300hp is on the weak side. However, a ZR1 with 375 or 405 can still just about beat most cars you will see driving around. If your car has 450 HP or 410 gears etc then your chances are even slimmer of being beaten. I'm 10 years older and smarter now and I have nothing to prove anymore. I rip off a few gears here and there because I enjoy the rush. I can appreciate other cars and if they are faster great. But honestly when I do drive my ZR-1, I pretty much do feel like I'm driving a KING and not much on the road can touch it. I'm not ignorant, I know about all the twin turbo C5's with 1000hp etc but they are few and far between and quite honestly I have no interest in putting a $100,000 into a Corvette to have it setup the way I would want it. Maybe when $100,000 means nothing to me and is chump change I'll do it. Another thing, I would be arrested and thrown in jail if I had a car with that kind of power. Anything in the 400 range already gets me into trouble.:dancing

[rhipsher]

This car is basically a Ferrari Testarossa. And the only reason it didn't sell for $180,000 back then is because it wasn't made in Italy. And thats the plain truth.

[WB9MCW]

I feel about the same and find 400hp to be enough -- sure a 500 hp Z06 or a 600+hp ZR1 would be great but why not a 600hp LPE LSV like Ron our ZR-1 Net/Reg Prez has?

You know it is a far better bargain than either of the C6 models and with some coil overs and a few other extras you have good ride for the track too. Even a C5 Z06 with a blower and suspension mods is a easy way to be at the top hp wise and have plenty of $$ in the pocket.

Now that is how to do it on a decent budget for us regular folks.

Sure if you have the $$$ and really want the exotic well then fine more power to ya-- but most of us are not in that "new rich" or "old money" category and have to live within a reasonable budget.

Thank goodness for the Vettes and Vipers that make it a reality for the "ordinary folks" as our new Prez O calls us --- Guess we were not cut out to be part of the "PROMINENT CROWD" and drive the Exotics... :sign10:

I know we have some members her that could if they wanted to own an exotic and some have even went out and done such only in the end to come back to the KOTH because they just plain missed their KING and are quite happy and content being a ZRONER especially when it comes time for the repair bills versus the exotics.

A good bargain is always a nice thing and makes you feel good about yourself and your ride. And proud to be an American. :thumbsup: :cheers:

That is what makes the new ZR1 a winner too at little over 100K but a bit pricey for the "regular-ordinary guy".

We will leave the Exotic Euro rides for the PROMINENT ONES!!! :worship:

[Toms94]

The Z07 package is the "Special Performance Handling" option, available on coupes only between 1991 and 1995. It featured special high rate springs, the FX3 adjustable shocks, larger front and rear sway bars (30mm and 24mm respectively), J55 heavy duty brakes (this was an upgrade for 91-94 model years and became standard on all the 95 models), performance axle ratio, sport seats, 9.5 wheels at all four corners and 275/40 tires (again this was only different for the 93-95 model years as those were the standard size for the 91-92 Corvette).

Production
1991 = 733
1992 = 738
1993 = 824
1994 = 887
1995 = 753

Total Production = 3935

These cars typically can/will out handle a ZR-1 on an AutoX course, but where all out horsepower is required or where the power can be used, the ZR-1 will cruise past the Z07.

I have 1 of the 887 94 cars, the ride is what I would call "firm", not at all uncomfortable to ride in for extended trips. My wife and I have made several long trips in ours, three trips in which we put from 730-840 miles in one day. With the FX3 setting on "Tour" the ride is very acceptable.

[GregCrowe]

Yes, I actually traded my red 92 Z07 to upgrade to my ZR1 8 years or so ago. I have a 92 Motor Trend or Car and Driver lying around somewhere where they tested both against some other cars. The Z07 was the best handling of all the cars on the road course. My 92 auto Z07 was a freak. With gutted cats, borla mufflers, 52mm throttle body, 1.6 ratio full roller rocker arms, Adj. FP regulator and cut out filter lid, it ran a 12.72 @ 108mph in the 1/4 mile.

When I got my ZR1 if felt so smooth, I had no idea if it was any faster than my old Z07. Sure enough, so smooth it was deceptive, 12.32 @ 114 mph.

[Pete]

Bryan,the ZR-1 will remain a bargain as long as parts are available and cost stays withen reason.

Otherwise we will have a bunch of ZR-1 exotics that only the rich will be able to afford parts to keep them running.

Good point Pete!

Shame to think if that day ever comes.

Guess we would have to sell out a get a used C6 vert and just be a regular vette guy:thumbsdo:
