  • Material: Premium aluminum alloy
  • Weight: 7.15 lbs.

Key Features:

  • Flared bell configuration with strengthening ribs for added rigidity under load
  • Threaded rotor mount holes compatible with standard through-hole mount rotors
  • Compatible with T-nuts or bobbins designed for use with dynamically mounted slotted-hole rotors

  • Designed for use with matching Wilwood rotor hardware kits for solid, reliable performance

The 170-13585 is part of Wilwood's comprehensive lineup of precision rotor hats, purpose-built for high-performance street and competition applications where upgrading to larger brake rotors requires a properly matched mounting interface.

quick

Easy, Cheap prices

Everything was fine, but your order page would not let me chose to pay with paypal yesterday. It worked today.

Best pricing I found for the K&N filter I needed and the order process was quick and easy. Shipping time is reasonable and I have absolutely no complaints.

The ordering process has been quick and easy.

Really easy and fast

Easy.

Hope I get the parts I expect some of the description is hard to interpret.

great

thanks
