I put as mentioned above more effort in rotational mass then unsprung, seems bigger bang for the buck, every car has to accelerate and stop, put hitting bumps is more of a choice?
Which means big rims, tires, and/or rotors beyond the application's needs, has a performance downside.
Problem is there are no good 15" tires and even 16" and 17" are getting sparce.
I'm about being forced now into 18" rims because i'm worried about 275/40/17 losing selection soon.
