QM Twin

I read through another thread started by evodude where he shaved .025" off of the flywheel side of the QM discs and was able to double the life of the clutch. I know that QM released a new clutch not too long ago and I wanted to find out if the new version implemented the shaved down hubs, or if this process would still have to be done by a 3rd party machinist?

Just got off the phone with Adam over at MAP and the new QM clutches will be coming out in about a week. They will also have a newly designed hub that is thinner to address the issues seen with the prior design and forgo the necessity of milling down the hubs.

I think I should have waited to get my QM til this new version comes out. Oh well. At least I'm pretty sure that when I need to rebuild mine, that I can use the new version's rebuild kit.

If you have the older version then the concensus is to machine .025 off the flywheel side.

The old style you can shave. It works. Guy on here tested it.

The new style is a completely different design that cannot have the same issue as the current model.

The new style QM also has more input shaft spline engagement. Win-win. Buy the new QM if you're on the fence. I've been waiting since January for the new QM. It was only a month away 6 months ago. So now they tell me 2 weeks...must be another 3 months. I'm certainly not holding my breath.

The triple has a higher MOI... won't shift as well. This twin has an exceptionally high torque capacity...so IMO I see no reason to go to a triple

It would be nice to see some pictures of the NEW style QM twin for the Evo.

The new QM is a 8.25 not a 7.25, which means heavier and more streetable.

If you like the QM for its lightweight, def don't bother waiting for the new clutch.
