Complete tetra disc 140mm race clutch kit from Spanish RSX Racing
 
140mm tetra disc racing clutch kit for Porsche 997 GT3 RS Cup and ultralight weight flywheel(3.16 kg), same as the Sachs unit that Porsche racing fits in its 997 GT3 RS Cup, but ours, apart from being made of a single piece and therefore more compact and reliable, it is also much more resistant (we use forged Chromoly steel with our special "nitriding treatment"), offering also a longer lasting, as Sachs offers a hardness of 14 HRC on its flywheel surface and 32 HRC in the ring gear, while ours has 60 HRC allround and for a much lower price.
 
We sell any spare part of this kit and we also have a package of floating and top plates plus clutch discs compatible with the Tilton clutch cover that Porsche racing fits in their vehicles.
