A specialist range of racing developed brackets and mounts designed to attach seats. These steel sub frames are designed and manufactured by OMP to fix to the standard chassis floor of the vehicle. They are finished in a tough durable black paint and supplied brand new in OMP packaging. Once they are fixed in place, you then need to attach the appropriate seat mounting brackets between the subframe and your seat. We sell the full range of OMP seat fixing brackets on our website. If the part number has a D or S after it, then D stands for right side of the car, and S is for left side. If there is no D or S after the part number then this means that the sub frames are not sided and the same part number will fit either side. We supply subframes as single sides, or as a combo pack with both sides in.
