Default This post is going to take 3 weeks to finish (videos and/or pictures updated often)

We advertised here on the Corvette Forum this concept of building a inexpensive C6Z for the HPDE, Open track, Club racing, and ect.
Here we are on the last couple of weeks before the shake down test @ MAM on 4-11 and 4-12. I hope you enjoy this thread, as it will be updated almost everyday as we get closer. Then the customer will be running the Big Bend open Roadrace with his son in later April!!!

Here is part 1 of the build. Sorry No music yet, DRM jiggle will be added at a later date.




Thanks
Randy

I was going to ask how you attached a steel cage to an aluminum chassis. Then I realized you were using a steel chassis. Which made me think of something else:

Why didn't you change the rear upper a-arm mounting to be like the C6Z, or the front upper arms that use a cross bar through the bushing and bolting to the frame?

That'd offer easier camber changes, and I doubt it'd be much additional work to retrofit the chassis with it.

The front is the cross bar style, you can adjust the camber either on the lower arm or on the top arm, with shims. The rear camber adjustment is done on the lower arm. Not worth the cost of changing around the rear upper mount for the little benfit.

If the front end comes off again, I will snap a picture of the front bumper also.

Unoffical, + or - 10 pounds. The car has no weight for driver and a couple gallons in the fuel tank.

Doug and the customer are in a heated battle of guessing the exact weight. It's down to like four or 5 pounds. It's for steak dinner Friday or Saturday night.

One more interesting figure. The guys on the C6Z forum are winning the post war 48 to 17 on this thread.
