I am not sure who makes the aluminum spool other than Mark Williams. We do not have one of his spools in the car now so we would have to buy both.
We did switch to a solid roller from the Shubecks and solid cam we started with.
A lighter driveshaft might be in the plan also.
Has anyone seen a decent gain from reducing the rotating weight in the drivetrain ?
Jeff I did send you an email.
Thanks Again

About no gains here. Sounds good, but nothing on the time slips. Maybe something there for a low hp car. Larger the diameter the bigger the gains. Inertia is a b*tch.
Those steel wheels are a place you could notice something.
I cleaned the splines out of the right side of an aluminium spool on the staring line at Memphis once. It was no faster than my lightened steel Strange spool. 5 lbs lighter.
My MT slicks are 4 hundredths quicker than my same size Goodyears. Both dead hook. MTs are 5 lbs each lighter, but on a 31" circle, not a 9" circle. I have seen no gains from aluminium drive shafts either. 3" diameter. You think together they just HAVE to be worth something, even though we can't often prove it.
Light wheels (15" diameter ) would likely be worth a hundredth or two over steel wheels.
