I need all the drag I can get in low gear, so my approach was to 86 the Kolene's for Raybestos steels & grooved frictions I get from TSI. I can barely turn the input shaft with transmission on the bench now, so that oughta help out!
From the Kolene PR I'm reading, their coated steels cope with heat better, and smooth frictions do supply for more friction area.
If someone says something good about em, I might use em down the line in something. I've never used em.
Maybe a BBC pump gas street car. Those get hot.This message has been edited. Last edited by: Mike Rietow,
If I buy a new drum I will sand the black crap off, just snake oil IMO and stains the clutches. I do like the Alto smooth frictions for the additional grip. The Alto grooved frictions will apply slightly quicker because the oil has a place to go when squeezed. The Alto grooved are hard to find, Raybestoes are available from most anyone who sells clutches but at my HP level they do not hold up well. The way I look at it we don't have grooves in our slicks, why would we want them in our clutches?

When the pressure and clearances are right, they do not perform any better than any other "racing" clutch and standard raybestos steels. I prefer the standard steel, with the alto g3 black carbon lining clutches. The clutches are pricey, but they seem to take more, and are a high energy clutch, and are a little more "live" during apply.
