Our RMM is NOT like a suspension, or sway bar poly bushing, which WILL eventually squeak if not graphite/molybdenum impregnated, or greased with that poly specific grease.
I have a CP-E and it makes NO NOISE except for the start up/start off in first gear clutch release NVH and rumbling, which ALL of the aftermarket RMMs do to some degree.
NONE of the short shift kits on the market for this car actually shorten the height of shift lever itself (ONLY the throw), and about the only way to do that would be to either cut down some of the threads on the factory (or Boomba Racing lever), or by putting a shorter shift knob on the lever.
The kits for this car involve a 'plate' or different link which replaces the factory one on TOP of the transaxle housing, UNDER THE HOOD of the car.
In addition, Boomba Racing also offers a variable throw reduction (by changing the cable pickup point) shift lever which does replace the factory lever in the console.
(This is in addition to Boomba's own transaxle 'plate'.)
