Difference - swap M3 to 330i brakes/calipers
I have opportunity to swap M3 setup to my 330i ...
(m3 has 325 x 28 , my 330i is 325 x 25 size)
Does anybody know main difference between these two brakes ? Are they have same No. pistons ?
Is it worth doing it ? Will i notice any difference between this two setup?
