At the speeds you\'re likely to be going I don\'t think most spoilers will do that much.

As for wheels it\'s up to you, bigger than 18s is probably a no no for handling. Also make sure they\'re as light as possible.

The stock spoiler reduces rear end lift, the car becomes unstable at high speeds without it, it also tidies the airflow and reduces the drag.
Aftermarket one sometimes are fuctional some are purely for show.

17" wheels i think are considered the best for performance.

i\'ve had mine up to 140-150 on open road (my private open road, of course) with no stability problems. i have no wing and 255/45/17 tyres on the rear.

im sure i read somewhere that 90% of spoilers dont do jack unless you are doing 150+

the stock spoiler does nothing unless you have a later spec one. I\'ve seen the wool test (bits of wool tped to a car and then photos are taken when the car is moving, the air moves the wool so you can "see" the air flow over the car as the wool moves) on the FD and the 93 spec spoiler is useless.

so looking at it guess 17" stagerd lite wheels and something like the rz spoiler is the way to go

[chrisJDM]

yeh lightweight 17\'s would be the best way to go :Thumbsup!
