Home made copper clutch, Interesting read. 56K warning

[biglipzit]

Well i yanked the RB out of my car today for some serious overhauling and got the clutch out. It is a stock Rb clutch with the old organic grip material and disk removed and a machine shop made stainless steel one rivetted in its place. Distances measured and holes drilled for 5 copper biscuits. The Biscuits were bought from trinidad and are made of mostly copper but only a couple of millimeters thick. The clutch has been heavily abused in the car for 2 years now with many track days seen and wear is very minimal when thicknesses of old biscuits are compared to new. The old ones are a bit overheated and glazed over from slipping he clutch too much in traffic but i have never experienced clutch slippage ever from clutch failure to grip etc. Not sure how many of you have seen these biscuits for sale but they grip incredibly and do no damage to pressure plate or flywheel as you will soon see from pics. I hope I don't get too many negative comments about this. Well here are the pics since you have had to read enough.

















8 of the clutch biscuits costs $50US so you can imagine how much cheaper this clutch is to repair. Don't forget the pics are from after 2 years of hard abuse.

I'm thinking that you couldn't have saved that much $$$ over an aftermarket disc. You said $50 for the pads, but what about the stainless disk, machine work, and riveting costs? Compared to only about $100 for a decent aftermarket or OEM disk.

But maybe it costs more to source stuff in St. Lucia.

this is still a good job done. not because the cost or the machine work. it is that he find the way to think the way of avoiding the high cost... in ebay a stage 3 clutch cost 180bills plus shipping.... a make clutch. exedy s tege 3 single plate 400 to 500 bills. and is the satisfaction making it work at 100%. !!!!!! good engineering!!!!!good job

This is a DISK we are talking about, not a complete clutch assembly. Just the disk. And I am not slamming his work. I just do not think it would be cost effective in the US.

Pretty cool. I would probably just pony up the $50-100 for a new disk.
