Short version is..I have an improperly sized upper spring perch bushing.

GM has as much as 3/8" of an inch margin of error in bushing height...

With the way I have my coilovers set up it is just stiff enough that when the bushing moves that top nut just taps the trunk floor with the right amount of jolt... Like dropping off the curb on my driveway when backing out..

So, Pete and Bruce@Ramonds told me how to fix it... and I was a fixin it ..

and then I brokted it :(

There was a thread about that, affects one in a hundred, you're the one LOL
... I think I shall call you...

just ask PQ.. LOL

I had to do a few creative things to get my setup to work.
Like having John at CCW make some new rear rims to replace the new rear rims after we tried the first set of rims.. (It's not easy to fit a 12.5" wide 18" rear rim on these cars).. but now it fits, and it's a skateboard when they are on there.
or modifying the brand new, very expensive lower control arms from Spohn with a Grinder before I could race it.:(

My friends all love the ambition and dedication I put into my car during the off-season. They think I'm certifiable. LOL

They are glad I am entering race season where I don't modify stuff unless I have to - just tweak parts and the setup to dial it in. It's been a lot of weekends working late Saturday and Sunday to fit stuff together this winter. 5 months of building, shaping, cutting, stripping the interior, putting it back, trial fitting, etc. during this off-season.

I really like building the cars.. putting them together is half the fun.
Using them to their full extent is the other half.

Cmon' Fest!!! I'm ready to start using it!

Your car is looking great! Can't wait to see it in person
