Default Crash Bolts?

Do C5s have GM authorized (service manual or service bulletin described) crash bolts that can be used to get more camber in the front?

OK, now that SCCA has updated the stock rules to allow these bolts, I'll ask the question again.

Have you looked at the front suspension?

Camber, caster, toe and ride height are adjustable.

^^This. There is no place to put a crash bolt with our double-wishbone setup. And you already have more camber adjustment than probably anything out there.

I'm already maxed out in Camber and I'd like to legally get more. The SCCA just updated their rule book to allow the use of crash bolts to gain additional camber, if it's mentioned in the service manual or a tech update by GM.

Might try calling Pfadt Racing and asking them. Couldn't hurt.

Where do you expect a part used on a strut suspension to go when you have a LSA suspension?

Crash bolts are not mentioned in the service manual or any tech updates for the Corvette. I can promise you that.

There is already a pretty broad range of Camber adjustment in the front of the Corvette... I don't imagine that GM actually manufactured a second set of eccentric bolts for cars that had seen crash damage. Unfortunately I think you might be out of luck on this one.

I'm assuming the OP, in using the term "crash bolt", is referring to replacements for the two bolts that hold the front lower A-arm to the cradle that have eccentric adjusters on them (and possibly also the one bolt on the rear A-Arms that is adjustable).

FWIW, when I first read "crash bolt" I instantly thought of a Mac-Sturt front suspension like on a Mustang, where you have two bolts that hold the strut to the knuckle. In this context "Crash bolts" are either smaller in diameter than OEM or are ecentric. The idea being to give you some ability to adjust the relationship of the strut to the knuckle (i.e. adjust the camber). I think some of the other folks who posted thought the same thing.

Remove the flat washers that are located between the upper A-arms and the frame to get more negative camber.

The C5 with it's aluminum suspension parts and built-in adjustability would really have to be fixed properly after an accident at which point a street alignment would easily be possible. I would not feel safe driving a C5 that had a straightened crossmember or tweeked suspension parts.
