The last time I had my flywheel resurfaced for a 90 integra LS and it worked. I had a few problems with the clutch and I am replacing the clutch but when I took to the machine shop this morning the guy made me realize that this may not have been the right step up depth for the flywheel. Is there anyone that knows for sure what to get it ground for? I am not asking what you had yours done for and it works but if there is an exact spec. that is known for sure. Please post any links that may help.
