    Good quality and affordable

    Worth waiting for these pistons are well made, the only exception I could find was there was a good but of over-spray around the anti-friction coating, the kit I received 3 pistons were the same weight and one was 1 gram less. ( All over their advertised average weight)

    MAP came threw big I was quoted about a 6-8 week lead time they showed up less then a week later.

    Over all very happy
