    Ok it's not a review yet since my RMM is at a friend's shop right now having the stock bushings pressed out. I expect to install the mount with street PowerFlex bushings in both ends tonight and I will post my results. I'll have the first real test of my car this coming Monday with a low-key autox at PIRC. Can't wait to finally drive it hard!

    Yellow or purple bushings?

    My understanding is that yellow is street, black is race, and purple is somewhere in between. The website shows purple for the small bushing which confused me, but I ordered "street" bushings for both ends and received all yellow bushings ... which is really what I expected.

    Nice. Fit quality was good other than one washer that I had to file some burrs off the i.d. of so it would slip over the supplied sleeve. After a spirited test drive the change in NVH is almost imperceptible. If I try real hard I might be able to detect some extra vibration at idle and when pulling away from a stop, but it's barely there. The driveline feels tighter and shifting is crisper, but again not a gigantic change. I'm sure it will benefit the car in the long run especially when driven hard. I'd like to get a video of the mount like the one Cobb has for the Focus just to see how much things actually move now. As posted in other threads, the job is simple other than removing the factory bushing inserts. uploadfromtaptalk1400626822945.jpg
