Trust me. I've done all the bushings. I went group N for transmission mount, crossmember, and rear shifter bushing. I ordered the car with the STI short shifter (which comes with the front bushing). I've done kartboy pitch mount, aluminum carrier bushings, and all the whiteline rear bushings. STIs come with group N equivalent engine mounts. I did all this before break in was over...heh...so I don't know if it would have done it before. My bad.
Should I upgrade the front and rear shifter bushings from group N to kartboy poly?
