there are a few springs out there that offer a nice ride and nominal increase in performance (H&R OE sport, Eibach pro-kit, etc), but you'll have a hard time finding something that wont lower your car any. These springs lower a little over an inch, I think.

As for shocks, depending on your budget Tokico Illuminas, kyb agx's and koni yellows are all a good value... judging by your goals, the koni's may be overkill, however.

Good luck.
