I have a type R rmm on my civic and just put in the pernin inserts on it and wow what a difference. For $30 it's seriously worth it aside from the ungodly chassis rumble at 950 RPM. I have a CVT and when I idle forward the car vibrates like an earthquake. But aside from that I feel virtually no difference in NVH. Not at full stop idle, not while driving, not while in park. Is there a break in period for these inserts and this aggressive rumble will soon fade? I might have gone past the torque spec on the 17mm bolt but idk if that would make a huge difference. Any input on how to manage that 950rpm earth quake or is that just the nature of these inserts? If it is I'm not bothered, it's definitely helped wheel hop.
