Billet servos, frictions, and bands
Randy's a good friend of mine. His servos are very good. I replace the rear and intermiediate when "it matters". And I use his.
On the clutches - once they are installed and the unit is operating - there is no "time" to absorb fluid. They're already "at capacity". What you might want to do is give the fluid extra holes through which it can escape and shed more heat - but the material doesn't give or take away from the oils ability to cool. It only can withstand more heat or less.
