Just curious if anyone ever new this existed for 1st gen verts. What happened to x-braces for the later generations? Can anyone guess where it installs on the unibody? I'd guess at the subframe points.

Here is a link to an aftermarket x-brace from lgmotorsports:

Whats interesting is the part where it says, "NOTE: Will not fit convertible models, as they already have built in subframe connectors and an X-brace. "

I know about the built in SFC's....but a built in x-brace? Wonder if they mean "cross" brace or "x"-brace.

 

ive seen the x brace offered for 4th gens from classic and i think pst. converts come with factory subframes and the x wont go in because of the design "i think". makes you wonder what the hell the factory didnt put subs in the t top cars, or all the unibodies even.

 

I know....it stinks. Although they say that the unibody is stronger than a full frame car.

I started looking into it a bit and I've read in books about the 4th gen convertible. Evidently it wasn't ready in 93 (4th gen verts came out in 94) b/c GM was using a computer model to predict all the major stress points that would be present in a roofless car. They knew that previous gen convertibles were not that stable and corrected it by adding reinforcement in particular areas. Hence the 4th gen vert is the "most rigid camaro ever built". But they never mention exactly what they did to make it that way. I can;t find any specific info about what they did.

Chevrolet built all 4th gen verts (not ASC). So you'd think any added braces/members would be available to at least look at and get an idea of what they did.

I've seen the added frame braces GM used on the C4 verts. They used a huge x-brace along the bottom and three extra side to side reinforcemnets from front to back (a "wonder bar", k-member reinforcement, and a brace that attaches the rear shock towers).

But no one mentions whats been added to the 4th gen verts.
