I don't own a C4 Z07 but the cars have a special place in my Corvette heart.
Back in the summer of 1994 I did a long road test from the Los Angeles area up to the Black Hills Classic in South Dakota and back. Interestingly, the car I drove, which was owned by GM at the time, was later auctioned and bought by a dealer in the Phoenix area. It changed hands twice after that and is currently owned by a good friend of mine over there. Even more interesting is that '94 Z07 was the only Copper six-speed built. The car is driven almost daily and has well over 100K miles on it.
And, while we are talking about colors, the guys who own the Quasar Blue and Polo Green Z07s have to be proud of their very rare cars.
A little techie back ground on the option--
In 1989 and 1990, the Corvette Challenge cars (RPO R9G in MY90) were forerunners of Z07 and were built with Z51 and FX3 but without the suspension downgrade consumers got when those two RPOs were ordered. A statement was made here several years ago that at least one Z07 was built on the line at Bowling Green with special springs. I doubt that's true although it certainly is possible that some Z07s destined for the World Challenge were fitted with higher rate springs on an aftermarket basis...as were some Z07s for racing fitted with motorsports controllers for the SRC.
The Z07 chassis was composed of
Big front brakes
High rate front and rear springs (highest fronts in 1991, not quite as high fronts for 92-95, same rears for all years)
Larger diameter front and rear stabilizer bars (30/24 for 1991 and 30/26 for 92-95)
Higher durometer front lower control arm bushings.
Power steering cooler
275/40ZR17 tires Goodyear ZR Eagles on 91s and GS-Cs on 92-95s
Automatics had 3.07 axles
The Z07 RPO returned starting in 2011 and it had the same theme, lots of go fast parts.
As I said at the beginning, I was never lucky enough to own a C3 or C4 Z07 but I do own a 2012 Z07. One of three built with Carlisle blue, 1LZ and B92 and the only one built that way with RPO PBC.
Can I join?

What kind of questions do you have? Hopefully. I can help and if not, somebody else probably can.
Ok, so now we are committed Corvette fanatics. I was even more pleased when I found out that this car was being sold by Ken Lingenfelters own collection where it has spent the last decade at his museum in Belleville Mi. We got to meet him, and he sent his " car collection manager " out with us to give us some details about the vehicle. According to him the car was ordered by a GM engineer and immediately sent to Lingenfelter for a full, top & bottom mod. then delivered to the dealership for pickup. Well 15 years later Ken Lingenfelter, John's cousin who bought the company from John Lingenfelter's son's wanted to open a museum, or collection he call's it, that is only available to the public for charity event's. he has over 100 car's in this collection now, but at that time he was buying back some of his work because he didn't have enough. So this was one of the cars he originally bought back, and now he is changing a few of them around so he brought the one's he's weeding out to the Auburn auction with no reserve, My lucky day !
