McLeod RST - balance?
 

Is it true that I need to balance the RST twin with my flywheel before installing? Is this something that a lot of machine shops can even do?

I would get the balance on any clutch checked before having it installed. Better to find out now than after its in the car and vibrating.

Are C5 and LS1 F-body flywheels the same?

yes sir

Thanks buddy. That should solve an issue I have.

We recommend balancing the flywheel,adapter ring & p/p bolted together as a assembly. Make sure to index the unit after it's balanced and then bolt up the unit to the back of the motor and lining up the index marks.

I see. Guess I can leave the discs out.

That is correct.
