OS Giken .. is what I have been suggested various places now... seems like real option.https://www.nengun.com/os-giken/racing- ... ate-racing
Other-one, not so obvious, is SPEC Clutches. Got the answear:
"The st3+ is a very street friendly unit and holds 555 ft lbs. If that is not enough capacity, then stage 5 (670 ft lbs) or the twin disc (800 ft lbs) are streetable options, just not as friendly as the 3+."
Now... the st3+ 555ft lbs (750+nm) its enough. Sounds super, has anyone used "SPEC Clutches" products? It is tempting.
Edit: not launching. Track race (tarmac) and street drive.
