Next step after M3 Subframe Bushings
I went with M3 subframe bushings 4 years ago. Rear suspension felt planted and there was minor NVH from the Quaife LSD. Now after 84,000 miles and 33 track days the car feels cushy. I use NT01s for track days. Summer climate here is hot and dry. Are Delrin subframe bushings still a popular upgrade from M3 bushings?

I would go solid aluminum, do the subframe bushings in aluminum while you are in there. The bushings are not that expensive at all. Tuner makes a full set.

Whatever you go for, maybe you've got a vernier caliper and you could measure the diameter of the bushings before you press them in? That way I could make my own without having to take my car apart first! |

Those miles and track day took toll more on other suspension components rather than the subframe bushings. I assume it would still feel cushy even if you weld the subframe onto the chassis.

Try a diff lock-down kit, it worked a lot for me to get a rid off of any rear steer .-)
