I have not I have only done about 100 miles but I did put an oem back in and I have never installed an oem clutch I always go aftermarket just this time I went the cheap route and this was on sale. I never had a break in for my clutches but this always was for 6 speeds and ls1 engines in Australia maybe we make them all different out there I just put them in and drive as hard as you can. I am going to baby it for the recommended 500 and if it does not feel better I'm going for am aftermarket kit any suggestions on what's a good daily driver clutch for stop and go I want it to be driveable.
