I just got the OEM Performance SSK installed 2 weekends ago. I love it! I'm using it with the M-tech shift knob. Much better than stock with shorter throws and better feel. I was debating between Rouge and OEM and chose OEM Performance because I wanted to stay with OEM products on my 330i. It was worth the money.
