I vintage race a 2.0L six single plug narrow body 914, and for years used a Patrick Motorsport “901” style flywheel and Centerforce 215mm clutch package. I would like to go to their 5.5” clutch and ultralight flywheel, and I understand all the advantages, but I don’t know if that’s offset by lurching around the paddock and in and out of my trailer, and shorter clutch life. Will I forget about that on the track?
Thanks for the advice, Gavin |

What happens is that they warp
The more you slip them, the more heat The plates warp And there are specs for measuring the tolerances I’ve only replaced mine 1 time from wear |

They overheat easily and don't tolerate slippage like a stock clutch. Probably they "wear out" more from that, than from thinning. |
