What are the best suspension mods for the 370 for DD and some track use?

It is street car, I wouldn't worry about small weight savings. Anything short of driving ballz to the wall flat out on track you're not going to notice.

The cross drills in the RB brakes are fine, they can still eventually crack but are less likely to crack that fully drilled rotors (the braking surface is more heat stressed than the recessed areas).

Replacement rings for the RB's will run you about 250 a corner, maybe a little more once you add on the hardware.
