so i have just purchased an aluminum flywheel from another forum member. i knoew before hand that the fricyion surface needed to be replaced.

now my question is...

can you also have that fricyion surface resurfaced? or do you have to replace it because of the bolt holes? because i was thinking they resurface slotted rotors(not sure about cross drilled) shouldn't be any different. i have a place i can call but they have not been opened since thursday. so i haven't been able to

the friction surface doesn't have any deep grooves in it. but for a new clutch it needs to be either replaced or resurfaced if i can.

Don't listen to me because I have no clue what Im talking about..

you should be able to resurface it as long as there is enough steel left to not make contact with the bolts during the process... or after wear on the surface.

however the best thing to do is either talk to your machinist or the manufacturer of the flywheel. they will have expert opinions on the subject.

thats what i was figureing

I would say no, if you machine the friction surface you also have to take off material from where the pressure plate sits. Thus, when it comes time to replacing the friction material you will have to add material....

See where this is going?

yes i can see your point but usually as far as i have seen when a flywheel gets machined the surface the pp sits on general does not get machined

Well, then whoever machines your flywheels doesn't do it correctly. If you don't machine both the pressure plate will not sit at the correct preload and can cause a loss of clamping force.

i understand the clamping force issue but does a couple thousandths of an inch really change much.
