Bumping this thread with a review of my newly installed 88a AWR RMM. Thank you Ron @ Whoosh for getting this shipped the day of my order!
After just a few miles, these are simply my initial thoughts at the moment.
Let's start with vibrations since they are typically a big concern next to performance. At COLD start idle, vibrations are hardly noticeable. I'd easily say the car still idles 90-95% smooth as if the stock RMM is still there. Honestly, even with the AC on, my opinion is still true. Vibrations are a non-issue at idle. Upon take off/engaging first, that's when you feel the difference. The car will vibrate each blip of gas you give it to take off and is VERY noticeable.. Like.. Holy crap noticeable. Would I say this is a bad thing? Not at all. I know for a fact this mount will break in and feel much better after 500-1000 miles. If it doesn't break in, would I be mad? NO. Read below as to why..
Performance.. I'll keep this short and sweet. No longer do I have to baby clutch engagement to get smooth shifts. No longer do I dread the downshift into 2nd before a corner.. The car feels so much better connected to the point it honestly feels quicker. Between acceleration and deceleration, you feel 0 engine movement. It's so night and day different that if I got in 2 FiST's blindly, one with the stock RMM and one with the AWR, the first mod I would guess is that a stiff RMM like the AWR is installed. It seems lots of people played it safe and went for the 70a bushing, but the 88a seriously is not bad. I'd prefer the harder mount to ensure it does what it needs to. Many suggested against this, but I went with my gut feeling and thrilled that I did.
In summary, everyone should do a RMM. More specifically, everyone should do the AWR RMM because this piece is insane quality + provides durometer options. It bolted right up without a hitch after I realized how it needed to be oriented with its own, pretty bracket. I'm probably a novice or less, skill-wise, when it comes to installing car parts, and this was mind-blowingly easy lol.
