What splines and disk are you guys using for your Tilton 3 disk clutch systems. Where are you getting your flywheels?

I used a 7-1/4" triple copper disc unit.
Originally on the stock 914 trans but using a smallblock ford V-8 flywheel pattern. Got drawings of the adaptor on my site. So far it all takes well over 1000 ft/lb without slipping.

I have a spare set of stock splined discs that I don't need since when I upgraded to the 930 box it needed the larger splines. I'll let them go cheap! IPB Image

Don't know if that helps any since it was all pretty custom.

Although I have a six for my EP car. The flywheel comes from Fidanza. Order now if you want something by the spring. They have aluminum flywheels for type 4 motors I am told. As far as the clutch goes Tilton 5.5 twin disc with standard splines, just call them they are very knowledgable. The release bearing can be tricky, but I think you could use the standard bearing with a reducer for this clutch. I had to engineer a hydraulic release bearing due to my odd (Hewland)transmission config.

Here is a picture of WEVO's flywheel on the tube frame 914 car.

And here is the throw-out bearing.
