said it before and ill say it again, u get what u pay for, Kimpex pistons are cheap. Now i know that oem are way over priced imo, few people have good luck with kimpex and many dont. I am using wiseco in mine and no problems so far. I have a set of Kimpex pistons and rings for a standard bore 488 (72mm i think) that have about 10 minutes of use on them sitting in a box for the last 2 seasons( its a long story)

I had Wiseco pistons put in my Grand Touring 600. Blew up after 400 miles. The shop said nearest they could figure is that the cylandars were not bored out enough. Turns out Wiseco pistons require in extra 5-10 thousands becaouse they expand more. Don't know if this was done by the guy who did mine. This scares me. OEM for me from now on.
