Manual Transmission - What Twin?

I am in need of a new clutch.
car is right at 4000lbs , about 700rwhp , gets driven almost daily in the summer at raced about 8 times a year.
leaving at 6000rpm+ with ET drags
SDPC has ram twins right now (is the adjustable master really required?)
Mcleod twin?
RXT?
what should I get

I just bought the Mcleod st myself

We've had a lot of luck with the SPEC Twins, and we're down and dirty on the price as well:

I definitely suggest our adjustable master kit for a twin disc car - the factory hydraulics are going to be begging for mercy if you don't upgrade.

McLeod here and never been happier

If you want to use the factory flywheel use Our RXT 6932-07. Good for 1000 HP and has the pedal pressure of a Honda. If you want a flywheel use a 460530.

well I picked up a street twin 64050B-00-07 . hopefully this was a good choice
