I can get a cinder/iron/brass dd clutch made to hold over 1000 hp and hold to sled pulling and is very street drivable, for $600 bucks. This guy invented this clutch his self and also said it uses the stock hydralics also. While I am at it I am going to get a full flywheel to replace the dual mass, and I think I am also going to get a hydralic up grade get. what are your thoughts on this clutch and have any of you heard of something like this before. This info is going from the shop manager at my dealer because they do performance mods also and this is what he found out.
