I might have to try something creative to fix my mini too. I've tried keeping it stock, but on acceleration or hard braking my controller shakes fairly violently like I AM going over cobblestones, even though Im on the test course. Once I get to the high RPMs of 3rd gear, it subsides. I've tried changing TCS, ASM, I bought the semi-racing suspension and tweaked every setting I could, going from one extreme to the other and testing the middle ground as well - nothing seemed to make the shaking any better. Any ideas?
