New clutch and flywheel
I'm currently having a new aluminum flywheel and clutch installed along with a DTE 4.10 differential. Is there a break in period or seating process associated with a new clutch?

I just had a new clutch assembly with light weight fly wheel, and 4.10 hardened gears put into my car earlier this week. There is a break in period for both the clutch and the rear gears. It takes 300-500 miles to be safe. No hard cornering at all; no burning out or quick starts; limit your speed/RPMs to get up to speed - just take it very easy. It also helps to drive a bit (about 8-10 miles), and let the car cool down for about a half hour. This let's the rear gears strengthen/break-in properly. You also need to change your rear fluid after 500 miles (metal deposits).

Thanks! I was primarily curious about the clutch. I'm having DTE put everything in and they have already told me a little about their break in. Real pleasant experience so far. They'll be done tomorrow and I get to drive back to Cleveland.

I don't really think there is a break in period for a clutch. There is nothing really to brake in. I changed mine out last Saturday and did take it a little easy the first few days. Got on it today pretty good and all seems well; no slipage no odor no problem.
It's been going out for a while; s/h replaced it sooner. Only cost $200 for a Z06 type clutch with a balanced flywheel so it was cheap enough. 10 hour install but not really a big deal.

I asked Phil from DTE the question before I left his shop on Saturday. 300 to 500 miles was his recommnedation bearing in mind 500 freeway miles would be good for the gears but won't do anything for the clutch. The clutch needs to used with normal frequency. By the way, Phil and Jenny from Dynotech Engineering were great. Very happy with their service.

I'm glad my information was correct. ECS also said to change your rear differential fluid at 500 miles as there will be metal shavings in the fluid. He said you don't have to do this with a new car as the stock rears have been tested/blue printed. Thinking about this though, I'll be changing fluids on the next new car I buy after the break-in period, just to be on the safe side.
