253 WiLWood 13” rear Brake Packages For Mod-Lite & Grand National Floater – For Aluminum or Steel Hubs These track brake packages are for Race Style Floater Rear Ends. On these packages we utilize the Superlite 4P caliper. This works well with the 2.46” or 3.00” piston area we configure them with. We suggest running the 2.46” piston area calipers if you preference leans to less rear brake. Consequently, we recommend the 3.00” piston area calipers if you preference leans to more rear brake. Of course you can balance the braking with a bias bar, either way, but the 3.00 version will allow more total braking force.
