Centerforce here
After burning up the first clutch in exactly one day, I went with the Centerforce dual friction unit, I think I bought it through JEGs. Can't recall the cost, but it's held up about 4000 miles to far. Only a little abuse now and then
.
BTW, I did not follow the break in protocol for the first clutch, I think they recommend 500 miles before attempting to put a sudden load on the newly installed unit. I waited about five feet, then dumped the clutch. Hey, I had to see if the engine was OK
. I was nicer to the Centerforce unit...
Good luck!
