I just picked up an 2004 s2k with BBS rxr's, BC coilovers, and an AEM V2 intake. Will soon be picking up an Invidia Q300 exhaust. What performance mods are a must have for ap2 s2k's??

 

Best bang for buck is going turbo.

 

I think the best performance mod I've done so far was a test pipe. It really helps the throttle response, and makes the car feel a little more alive, but you do lose a little low end torque untuned. Best mod I've done that wasn't necessarily performance was a Moddiction Round Anvil shift knob.

 

pfft... leading the man astray already.

 

had a 70mm test pipe but had to buy an overpriced california approved cat to get it smogged, i'll be sure to put it back on once i get my exhaust!

 

Trading me your bc coils for my function and form type 2's and maybe some cash on my end

 

 

good tires

 

This. And getting used to the car before trying to add more stuff to it.

 

Start off with tires.
