So a lower sidewall would probably increase understeer all other things being equal.

When calculating the tire diameter, you need to double the sidewall height...  |
Now that we have the 19's/20's figured out....
Any idea why they switched to a floating rear brake caliper from the 2-piston in regular form and 4-piston with CCBs?
I doubt that a floating rear caliper has as much clamping force as a 2 or 4 piston caliper. Or is it all for weight savings and they've offset it with a larger rotor?
One thing I find with my M3CS is that on track the brakes aren't the most confidence inspiring... I'm completely stock down to the pads/lines/fluid, standard brakes, no CCBs.
Since you have a near identical car and infinitely more knowledge about these, figured I'd ask!
