If you're interested in how the steering feels then changing the front wishbone bushes as well as the rear anti-roll bar bushes for poly will benefit the feel. A strut brace will improve matters nicely as well.
Going up the price range, 17" wheels and tyres sharpen up the steering whilst looking the part .
I've also been looking for exhaust pieces. Engström has a full JT 3" exhaust for $595 (£331.96) and the stage 3 ECM upgrade is the same price. The stage 3 wants me to have the 3" downpipe(optional race cat),2.5 or 3" freeflow cat-back, and an open-air air filter. but with the LPT ECM I have now will it limit the ammount of power I can get from my engine and turbo? or should I just stick with rims?
