Hey guys, as I'm getting more into tuning and bolt-ons, I've been considering a RMM upgrade to help get power down to the ground more efficiently. I daily my car about 50 miles a day, so I don't want to ruin daily drivability with excessive NVH. I can handle an increase in vibration if the trade-off is worth it.
I have the options of a full RMM replacement between 27WON (90A) and Hasport (62A, 82A). I see that Perrin and Whiteline also make RMM inserts to fill in the gaps in the factory RMM bushings.
Anyone have any thoughts on inserts vs. full replacements? Can you feel a difference with just the inserts? Anyone start with one and switch to the other? Thanks!
