Ideas on improvements. Rather than getting bigger tires why not raise redline to 8000 rpm? You can still grab power up there and gives you a little more top end while keeping low end responsiveness.

Aluminum hat rotors? Huge rotating weight reduction.

As for the SPC arms, I believe the rule is something like... "the ratio of metal to rubber cannot be greater than stock." The stock arms bushings look like they're the same ratio... although, I haven't done the actual math.

I do plan on getting the Z1 aluminum hat rotors. Those save 10lbs a corner.

I did think about raising the redline. Thoughts on what would be safe? **EDIT** I just read some of the other comments... I'd probably rather not raise the cars redline....
