Superforma – RB Oil Gallery Restrictors
Nissan RB cylinder block oil restrictors used to restrict oil flow to the cylinder head.
Fits all RB engines and available in 1.1mm, 1.3mm and 1.5mm.
All of our spacers and adapters are hubcentric, meaning that the weight of the car rests on the hubs and not the wheel studs. This means that our Superforma wheel spacers are safe whilst having no extra vibrations from the wheels.
Our PCD adapter spacers are perfect if you want to fit wheels from other manufacturers to your vehicle. The PCD Adapters can also change 4 stud to 5 studs. These are a much cheaper option that a complete change of the hubs and brakes. By changing the PCD and the number of studs, you can open up your possibilities on the alloy wheels you can fit to your vehicle.
