Resurface flywheel for new clutch?

[CA18Fastback]

do i need to get my flywheel resurfaced when i install the new clutch? if so, what does this cost? the reason i ask is because i had never heard this until my dad mentioned it the other day.

Thanks!-Ian

just take it to a machine shop, they'll quote you (as it si labour) and it only needs to be taken down a couple .001" to get smooth in most cases, just gives the clutch assembly something clean and smooth to grip onto to put those jdm horses to the ground.

its like 15 bucks at the local mechanic place around here.

i went to the machine shop today and he told me it looked like it had been cut before. he said he didnt want to mess with it cuz if he cut it down too far it might not grip anymore. what should i do???

Have your flywheel grinded to your specs by the machinist , not cut in a lathe!

i dont know what specs i need. i just need it resurfaced for my new Spec Stage 3 Cltuch. I just want it to be smooth dammit! Suggestions?

First off, if it LOOKS alright and feels smooth it probably doesn't need resurfacing, though its probably recommended that you do it anyway.Go to another machine shop or just find a mechanic. Tell him you are changing your clutch and need your flywheel resurfaced.Any place that does brake work can probably do it, since they resurface rotors anyway.

cutting a flywheel in a lathe is not the proper way to do it, perhaps for a "non-performance" car , but for a performance car/clutch you want the flywheel surface really flat. It must be grinded. I don't know the name of that particular machine. But for an exhample , if you look at a picture of a new flywheel, you can see the scratches/pattern and you will understand what I mean. Not like an LP record a lathe leaves behind!

Thank's

you should get it surfaed ground as already said...NOT in a lathe

if you are fitting a new clutch i would ..just the minimum tho....lot easier than pulling ouot thr gearbox after you find a vibration

All depends on the machinist, I did my friends KA flywheel, and 2 Chevy Luv flywheels for 2 friends on a HUGE lathe we had at school (I'm a machining student) and I got those to within .0001 of an inch. Some flywheels are too far gone and it sucks *** to machine, though.

aside from that, if I was paying someone (since they didn't pay me) then I would make sure the used the grinding wheel.
