With the body kit and stock 17" rims, my S2k seems like 18" rims would fit the wheel well gap better without lowering (low enough as it is).
However, 18" are heavier rotating weight, and would lead me to have to lower the suspension by 1/2" to prevent the larger rims from raising my ground clearance.
For the track, are 17" or 18" better for an S2k (AP2)?
