Best chassis for track car? Options

[FWD-3SGTE]

Hello everyone! Newbie here to the site and the 6th gens

I previously own a 5th gen with the 185 swap. I think I want to swap over to the 6th gen chassis because Ive always liked these more. I plan on throwing my 3SGTE in there along with some suspension, simple body kit with wheels etc. Ive been doing alot of searching, but its hard to find a discussion on this. If you guys could post your opinions on this, that would be great!

So lets say I wanted to build a full out track car, what chassis would you reccomend?

Im asking because I dont know the difference between the 94/95 chassis and the 96-99 chassis. I will be looking for a hatch back, and I do know that the 94/95's have the 2 post spoiler which I do want, but what about any other differences? Suspension wise, motor install...wise. And I know it will be cheaper for me to find a 94/95 chassis rather than a newer one Let me know what you think and sorry for all the blabble! Thanks soo much!
