I offer Sachs clutch kits for all I5 and V6 biturbo applications.
Basic S2 clutch incorporates CrMo flywheel, Sachs SRE pressure plate and unsprung 4-puck lightweight disc.
CrMo flywheel is better for sintered clutchdisc, which have habit of penetrating to the flywheel surface.
Crmo is also safer than cast iron ones, especially when revving high. Cast iron flywheel may explode on high revs, due to resilient nature of CrMo, it will never explode, no matter if You miss a gear and overrev the engine to 15 000rpm. It may shape shift, but not explode.
CrMo has also features over aluminium. Being a single piece, it is more stout than aluminum. Also the crank bolts do not penetrate the material like they do into aluminum over time. Furthermore, Crmo is resistant to excessive heat caused by heavy use on track or violent slipping, than aluminum with separate wear surface.
Unsprung disc is lightweight, and thus helps the otherwise problematinc 1st->2nd gearchange. The lighter the disc, the smoother the engagement on fast gearchanges. Unsprung disc is not on-off, like people think, but it is 'edgy', but in a sense anyone can learn to live with.
Lifespan of sinter disc is smaller than organic disc, but with reasonable use and minimized slipping on normal driving we have seen 50 000km driven discs in reasonable condition come out of 500hp cars.
Disc itself is repairable with small money. Also new disc is available separately.
I strongly recommend all projects exeeding 450hp, to consider replacing the cast flywheel with CrMo one. I also personally refuse to sell the press plate only for +450hp projects about to be used wit cast flywheels.
Flywheel comes in zero balance, and therefore requires no balancing, if Your engine is internally balanced.
These clutch kits are good for up to 550hp/600Nm with reasonable safety factor.
Kit price is 1350 eur for both, 016 and 01E transmissions with I5
Just the disc costs 190 eur.
I try to keep these in stock, but sometimes lead time is from 3 - 6 weeks.
