Mahle. The power pack pistons with the high end alloy are around 520 and are considerably more quiet than the weiscos, CPs, etc. The only pistons GT uses.

yea I was under the impression that one goes for the Wiseco/Eagle combo if they wanted over 500whp..
I guess not in a DSM.
My pistons were starting to go at ~500whp.
Was told by my tuner to replace them with Ross pistons.

But anyways...had some isues with the 4g63 and switched over to the EJ257.
