I would have to say that they are about the same. The hatchies tend to corber better than the coupes, due to a stiffer frame from the whole top being covered, but between my 92 coupe that i had and the 89 that i have now, there is not much difference. it will depend largely on what you put under it for springs, shocks, tiebars, stiffeners, etc. I would have to say, that if I had my choice, and all the funds to do either, i would do boosted b18c1 in a 92-95 coupe. it's a super simple swap, almost no changes to be made at all, and you have a crazy fast car with a lot of potential. But, if you want something (in my opinion) that looks better, go with the 4th gen. i love the lines and the body style, and the 5th gens just look funny, to me. just my $0.02.
