CHanging my clutch on MY97 sti type r. I know a place local to me who can skim or lighten the flywheel. Is it just a straight forward procedure once I give them the flywheel or do I need to tell them certain things, weights etc...

 

No you shouldnt have to tell them any thing specific if it is a reputable place they will know their stuff. The procedure is fairly straightforward as the name suggests they skim a thin layer off the flywheel. the only proviso is there is a limit to how much can be skimmed so make sure you question them about this. good luck.

 

Skimming can be done at more or less any machining shop. To have it lightened is another matter though.

May be easier to buy one already lightened.

Speak to Alyn (stockcar) who may be able to sort you out.

what weight have you got in yours bob?

 

Dont forget its a double faced flywheel Around £30 on average for the skim

 

If you hadnt seen it already, Adam M is selling a PAR billet flywheel in the for sale section. £150.

 

Double faced.???.... please explain.....

 

Needs 2 surfaces to be skimmed first the drive face then the mating surface of the cover area for obvious reasons..
Must be an engineering term

 

From what i remember from when i changed my flywheel, it's all one surface..... maybe i have a crap memory..

 

Mine was stepped ron only about 2 mm and the guy asked is it a double faced f\wheel to which i replied You learn summat evryday

 

4.2kgs

 

4.2 kg thats pretty light. most i have seen are 6.8kg, was best to get?

 

Depends on what you like really. If you're getting the OE one lightened you can only safely go down to 8kg I believe.

Aftermarket ones are obviously more expensive than just machining the OE one.

The v light flywheels require a bit more skill for launching hard, but are worthwhile IMO. Some people dont get on with them at the drag strip, but I dont have any probs.

Adam has an aftermarket one for sale I believe which isnt going to cost too much more than a machined OE one.


Bob

 

Does it really make the difference? Would I be a fool not to do it as I'm changing the clutch

 

IMO opinion I would choose a lightweight fly everytime as I get on well with them.

Not everyone does though.


Bob

 

When you say you get on with them, what do you mean, I take it it feels different or there is a different clutch pick up?

 

Some people find it difficult to launch well with a light flywheel
