RCM POWER PARTS
The RCM Power Parts range is built on a deep motorsport heritage spanning 6 decades of competition at the highest level. We are happy to offer engineering solutions which are driven by a desire to succeed and the Passion to Win.
AFR Autowork’s drag car along with RCM’s Gobstopper Race program is the perfect test bed for all our products, allowing parts to be rigorously tested and proven before being made available to the Subaru market.
Some of our favourite RCM Power Parts are the “Subaru Alloy Camshaft Pulleys” to replace the Bakelite cam gears that come on many EJ Subaru models, the “RCM High Performance Oil Filter” which is designed solely for use with high performance Subaru engines, along with their modified oil pumps and “RCM 4-Stage Dry Sump System” for the EJ20/22/25 for the ultimate in oil system performance and protection.
STI SPORTS PARTS
At AFR Autoworks we are able to offer a full range of STI Sports Parts. Subaru Technica International offers a large range of street friendly performance parts which are upgrades of standard Subaru offerings. Group N engine mounts, STI triple pillow ball lateral link sets, and Group N strut mounts would be some highlights of this collection.
NEW RCM PARTS
Roger Clark Motorsports is constantly developing new Subaru performance parts.
One of their exciting new products is the “RCM600 Subaru Twin Scroll Precision Hybrid Turbo” which utilizes Precision’s 58mm Gen 2 turbo with RCM’s own twin scroll turbine housing for the ultimate in Subaru stock location twin-scroll turbo performance. We have made over 560whp (650bhp) on the 58mm Gen 2 precision turbo. This twin-scroll turbo option is available as the RCM500 as well which utilizes the 55mm Precision turbo with the Roger Clark Motorsports twin-scroll turbine housing and wastegate.

We sell the Roger Clark Motorsports “RCM Eccentric Adjustable Idler Dual Bearing Set” to many customers to help keep their camshaft timing as accurate as possible. This is especially helpful when cylinder heads, block, or head gasket thicknesses have been modified.
