Schrick has developed this high performance rocker arm based on the original factory E46 M3 rocker (cam follower). Schrick coats the contact pad with a DLC coating for reduced friction and improved reliability. The stock S54 rocker arm is un-coated. With more aggressive camshafts there is much higher force and friction on the contact pad which will not only induce more wear on the rocker arm but also lead to higher temperatures and thinning of the oil in a critical spot. The Schrick rocker is preferred over the stock part with any of the more aggressive S54 cams (304/296 or high lift, etc). The DLC coating is extremely hard (DLC = Diamond-Like Coating) but with a graphite content that allows for low friction levels. The DLC coating resists oils and chemicals so it's perfect for an internal part like a cam follower.

New rocker arms are required with any new camshaft installation. Sold per rocker arm.

These WPC-treated bearings are the best we have seen! WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are original equipment KS bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.

These bearings replace the factory BMW rod bearings. The original BMW bearings have too little clearance, which leads to premature bearing wear and can cause early engine failure. Furthermore, the factory BMW bearings are made from tin-aluminum which are 5-times harder than a softer lead-copper bearing design. A softer bearing is better for your engine and more tolerant of foreign particles suspended in your oil.
