I have the Mahle Forged in mine, these are first set I've ever had by them and I am impressed with the quality of them. I'm not saying they're better than JE, Wiseco or Ross/Probe but they're certainly not any worse and the slick metric rings were included with the price. Mainly went with them since I live in NC and they have a factory near Asheville. They are the OEM for many manufactuerers, including BMW and Mercedes.

My machininst does a TON of circle track and drag motors and he swears by them, hard to beat for the $$$
