K-Factory ZF Bearings
K-Factory have introduced their new ZF bearing range which come in a variety of sizes and are used as a replacement for your standard kit bearings. Lightweight, these bearings help reduce rotating and static weight within your car, while their construction, combined with the very smooth rubber material used for the seals, provides your car with an almost frictionless transmission system. Less friction equals more speed.
