Resurfacing a flywheel (1994)? - ZR-1 Net Registry Forums

Rusty · 07-02-2013

Has anyone resurfaced their stock flywheel? If so, has it been successful or have you had problems with it?

First, I know that the stock flywheels on the ZR-1's are not supposed to be resurfaced (says so in big, capital letters in the service manual). However, I've been in touch with Jim at Powertorque Systems who said that he has a pretty successful resurfacing procedure for less than $100. Based on my communication with Jim so far about clutch parts for my '94 ZR-1, and great recommendations from this forum, I'm inclined to put some faith in that statement. On the other hand, the shop I spoke with that may do the installation on my new clutch parts from Jim said, very emphatically, that the flywheels should never be resurfaced and that I'm setting myself up for failure and expense if I try to do it.

So now I'm not sure what to do. I'm not keen on spending $1,500 for a new flywheel if I could spend less and get my original one resurfaced, but I also don't want to do something I'm going to regret just to save some money in the short-term. For reference, the car has about 90,000 miles on it. I don't drive it very hard in general, but I suspect that several of the previous owners were far less gentle with it.
