Super easy to instal the car feel so good now. After 150k mile on my Si 2017 (80k mile tuned phearble 1.5) the OEM RMM was shot to death rubber was cracked and shreded. The difference know is like night and day, smooth shift direct response from throttle, that just amazing. I looking to keep the car as long as possible so it's a good investement.
The RMM is really high quality like any other 27won product this one is amazing.
Highly recommanded, this a most to have on 10th gen Si.
