Most efficient mod for $$$$$$

[drburton]

Your question is a bit vague b/c it really depends on what your goals are. If you are using the car on the track, the first thing you want to do is improve your driving through experience. Once you feel like the car is holding you back here are a few mods you can make:

- New lighter wheels and tires
- New suspension, Blistein PSS9 is a popular choice for the 987
- New exhaust and headers - dependent on what u get it is possible to add some HP

Personally, I think you should just work on your driving skills and worry about mods later.
