Can someone post the weight of the new spindles and hubs?
I have weighed both stock-style 12" disc brake spindles/rotors/calipers, and my CPP Modular spindles/hubs and 2nd gen CTS-V rotors/calipers for comparison. As you can see, the StopTech rotors are very heavy, so I'll probably end up using something lighter. The factory dual-cast rotors are lighter but GM recommends replacing them every pad change so they won't last long on a truck built for the track. I thought the StopTech rotors would last longer.
12" Stock-Style Disc Conversion Parts:
- Spindle/Rotor Assembly with bearings, seals, and pads- 55 pounds
- Caliper.- 10 pounds, 3.7 oz
Total assembly- 65 Pounds 3.7 oz, each side.
CPP Modular Spindles, CPP forged hubs, 2nd gen CTS-V Calipers, and StopTech slotted iron rotors- 2nd gen CTS-V fitment:
- Spindle 18 pounds, 0.9 oz
Total- 60 pounds 5.8 oz
