Ben I hope Speedtech can overcome the design issues with the 3rd gen platform. The front frame rails are very narrow at about 32" between them. The frame under the floor is even worse as it follows the contour of the trans tunnel and hugs a 7000R4 like a second skin. This leaves no room for long tube headers or collector extensions to run along side the transmission. The firewall and floor pan of a 3rd gen are made of 20 to 22 gauge sheetmetal and will require extensive plating and reinforcement to accept a bolt-in sub frame like a 1st or 2nd gen Camaro.
If you follow the posts on thirdgen.org the members there are looking for a suspension that provides a decent amount of camber gain so we don't have to run so much static camber; a spindle that will have a small scrub radius when running 305 or 315 tires; a tighter turning radius; decent akerman, and rack and pinion steering. Oh yeah it has to shave 30lbs off the factory stuff too!
I have installed a modified SLA front suspension from a 2000 Z28 into my 83 Z28. I used the lower A-arms, spindles, and steering rack, mounted on a custom K-member. The front wheels were moved 5" forward in the process to try and get a more favorable F/R weight distribution. Although it was a lot of work I now have a completely adjustable front end, caster/camber, toe and bump steer, anti-dive, roll center and ride height. I am hoping it will handle very well when it is completed.
