I would say upgrade your F-body with a tube chassis from Jeff, the chassis has the same road manners as the A-body chassis to some degree. All the parts on the chassis are good quality race parts. I would say get the frame bare and do any upgrades you want to do. As far as flex anything beats a flimsy F-body with a sub-frame. The connectors work and I know this for a fact, my buddy in high school built a 10 second 68 Pontiac Firebird (it was Pontiac powered) and the car had insane amounts of flex until he decided to weld in sub frame connectors. It used a narrowed 12 bolt with a parallel 4 link and coil overs.

The car improved quite a bit, but the car needed a cage so he could take the car to the strip. Once the cage was installed it didn't flex as nearly as much and was legal and ran 10.90s-11.00 all day long. I forgot to mention his dad was loaded and used to be a fabricator back in the 80s.


Moral of the story is F-Body's could use a full frame for any sort of hard use.
The body's with sub frames connectors and sub frame's are pretty good but far from excellent.
Im not just saying this on behalf of Jeff, I am giving my honest opinion about what my buddy and I observed and corrected.
Go ahead and tell me im full of myself if you would like.
