I run the transverse leaf from a 95 Z07 up front
I will sell my stock '88 Z52 front spring for $50 + shipping
My race car handles insanely well.
I have thought about switching to coil overs but when the car handles this good why mess with it?
Infinite adjustability means tons of time to dial it in.
For that matter I have a set of Koni adjustable shocks sitting in the shop that I won't put on. My Corvette challenge valved bilstiens work great. I don't want to invest time to start setting up the car all over again with the variability of adjustable shocks, the car is so fast out of the box, why bother?
I dissagree with those who say all race cars run coil overs, it is completely unnessessary.
Look at how you use your car, is it a street car with occasional track days?
A good set of sport valved Bilstiens is all you need.
The metal coil over springs add wt.
We could groove the Konis and add rings and springs and caps for a few hundred bucks and then reinforce the towers, but again, why bother.
My car builder is completely against it as well. this is in a racecar that is poised to set track records this coming season.
I wouldn't do it, and certainly not on a street car.
That's my $.02

When I talked to Reeves Callaway he explained to me the reason that they went to a coilover on the Sledgehammer and I was swayed. I don't race my car but for the street it handles much better than it ever did originally. I agree that it takes some trial and error to get it right but once it is it's good for a long time. BTW I too have custom valved Bilsteins done to Callaway's specs. I just have to set the ride height. 90k miles later and I still have very few rattles or squeaks which I credit to a more controlled suspension.
