My roommate has a oz rally lancer, my brother a gsx-at, and i have a evo..
For comparision purposes, the gsx holds its own well on stock suspension. I've felt a couple gsx's with JIC and tein suspension, and it made a world of a difference. Stock, it feels like a boat. When I installed my RMDSM rear sway bar, it made the car a lot more fun to drive. The understeer was a lot less than before.
my roommates's lancer is a awesome daily car. It has good low end torque, but lacks mid to top. The interior is damn close to the evo. He has upgraded eibach springs on his car. Let me say, he wooped my brother's gsx-at on the twisties near our roads going down(the gsx started tire squeeling and body sway was horrible on hard turns). Driving his car around made me get used to the evo.
The evo stock, is a damn good car. Just giving it a bit of gas and shifting at 4000rpm, the car feels like it doesnt have any turbo lag. Handling on the car feels good... (i've been spoiled by my buddies single turbo mkiv on teins, and a xs engineering turbo celica gts on teins, and a mr2 turbo ) I haven't pushed it enough on the handling area, but my close buddy (graduate of bondurant school of racing) test drove the evo and commented that it handles pretty sweet vs. his brother's STI.
on speed wise, i did have a fun run with my brother. He was driving the evo, and i was in the gsx. I put the gsx into 2nd gear, and him on 2nd or 3rd gear. Flooring it, the evo pulled ahead.. but the eclipse i was driving started pullin the evo in from 4-6k and was even became with it (on 15psi) by the time we let off because the evo's still in its breaking-in period...

(no suprise there, the gsx dynoed the same hp numbers as the stock evo at the vishnu evo dyno meet)
And that's all i have to say about that.. hope it helps
