Tomei has made an option to include their Competition Bearing Series product with our kits. All the engine internals are brought to static temperature (20 degrees Celcius) and blueprinted with 0. 040~0. 060mm clearance bearings. This eliminates the measuring and blueprinting process for the customer, so the kit can be installed with less hassle.
