It's very important to know exactly what the power holding needs of your car. The UR web-site gives you the holding of each stage so you can choose the one best suited to your needs now or down the mod road. Our clutches are designed to maximize holding power while maintaining longer clutch durability. Simply choose the holding power you need and your done!
A disc is only as good as the pressure plate it is matched to. Clamp load is important, but going to the highest clamp load is not the best solution. High loads put strain on hydraulics, thrust bearings, crankshafts and your left foot. UR plates do not need massive load increases as we focus on the capability of the friction material as a result our plates have modest load increases from 15% to 30% over stock. This means you will have the holding power you need without losing drive ability.
Kits include the pressure plate, disc, release bearing, alignment tool, and pilot bushing/bearing(where applicable). Take a look at our current lineup and if you have any questions about which disc is right for your car give us a call.
