I used to over think it too (coming from the Bay area), but its really not that bad with our modern cars. Tires are important and you got the right ones.
I have both the shifter kit and the bushings and I agree. If you have the shift kit already, the bushing makes no difference.
Maybe you could argue it would make a bigger difference if only running a stage 2
thanks! Iβm going to look for a rubber grommet to make it look cleaner.
It comes out as one button, there is a cover for the blank but if I drill it 1. I dont think its wide enough (come on COBB can we do USB-C) and 2, I might damage the traction control button.
