Hello to all. I recently bought a used M3RS 265.The car is stock 95000 km but it has some minor issues.Clutch slipps under heavy load especially with 4th and 2500 rpm and some vibrations + noise on idle.My technician said that for sure I have to replace it.He also says that I have to replace the dual mass flywheel due to vibrations and noise on idle with a single mass lightweight one. I know the benefits of the light weight flywheel. K Tec racing offers a low cost lightweight flywheel compatible with stock clutch.Have you experienced a lightweight flywheel in M3RS?Should I trust the K-Tec flywheel unit? Thank you in advance!
Single mass flywheels on the mk3 are supposed to be horrible and put more strain on your gear box from what I have heard.
I know that gearbox could be strained but my question has to do with safety first. Do you think sigle mass flywheel could be exploded somehow?I've heard that it is case sensitive part of the engine/clutch system.A bad quality material could be shattered to pieces and produce fatal results.That's why I'm asking for KTEC parts and their reliability.
Any single mass flywheel will cause vibration if the force going through it is not rotationally even and ballanced... and an engines force is not balanced. Single mass flywheels have been around much longer than dual mass have so yes they are safe.. I have one bought from KTec on mine, along with a rebuilt gearbox, and yes it does make the box sound similar to when the input shaft bearing was damaged KTec dont make them, so there could be various makers of them, but I have not heard of one shattering etc that was fitted properly, and there is only 1 way that these can be fitted to this crank Longevity of your main bearings, clutch and gearbox are probably shortened with a single mass in comparison to a correctly working dual mass. Id probably be more concerned about throwing a rod, head or block in regards to danger
Keep it original, as its meant to be, my mechanic refused to fit a single flywheel to mine due to the excessive noise and wear and tear.
Put a SMF on mine from Engine Dynamincs, had to replace the clutch after 4000k miles as it broke, and put a DMF back on.
SMF didn't fail, its bullet proof. We do think the clutch couldn't handle it though. I didn't want to go paddle clutch because of the driveability so went back to DMF.
Clutch can handle it, but it transfers the stress onto the input shaft which eventually kills the bearings in the box
