PARAGON S-Bobbin – Rotor Attachment Hardware Kit
Paragon Performance S-Bobbin hardware kit for rebuilding floating 2-piece brake rotors. It replaces AP Racing CP2494-type "float in disc" bobbin hardware and supplies enough parts to assemble two rotors.
Choose the bolt count to suit your rotors (16, 20 or 24 bolts for a pair of 8, 10 or 12-bolt rotors), then the S-Bobbin type and bolt length. The bobbin type is set by the rotor ring's flange thickness and the float you want, from 4.30mm to 6.35mm flanges with 0.2, 0.4 or 0.7mm of float.
Note: Measure the flange thickness and bolt length on your rotor before choosing the S-Bobbin type and length. Installation by a professional is recommended.
Features
- Stainless steel S-Bobbins in nine types (A, B, C, D, H, J, L, M, P)
- Aerospace-grade Geomet-coated bolts for corrosion resistance
- Bolt lengths of 22, 25.4, 27 and 30mm
- Secure mounting that lets the ring expand and contract freely through heat cycles
- Replaces AP Racing CP2494-type "float in disc" bobbin hardware
- Enough hardware for two rotors
