Product Details

The Wilwood 170-12647 is a Dynamic Bobbin Mount Park Brake Rotor Hat featuring a 1.54" offset, engineered for use with Wilwood's internal shoe parking brake kits. Precision-machined from premium-grade aluminum alloy, this rotor hat delivers exceptional strength while keeping weight to a minimum.

Wilwood's Dynamic Bobbin Mount system is a significant advancement over traditional fixed-mount hat designs. The system allows the rotor to move independently of the hat as it expands and contracts through repeated heat cycles, effectively isolating all thermally generated stress from the rotor attachment points. The result is a rotor that stays flatter, runs truer, and maintains consistent brake response and pedal feel over the life of the component.

Key Features:

  • Dynamic Bobbin Mount design — rotor floats independently of the hat to accommodate thermal expansion and contraction
  • 1.54" hat offset for precise fitment and rotor positioning
  • Premium-grade aluminum construction — lightweight yet high-strength
  • Precision-machined threaded hole design for use with through-hole mount rotors
  • Eliminates pad knock-back and rotor drag caused by thermal distortion
  • Eliminates hat distortion from rotor thermal expansion and shrinkage stress
  • Compatible with Wilwood internal shoe parking brake kits
  • All problems associated with thermal distortion are eliminated

Designed and manufactured by Wilwood Engineering using computer-aided design, finite element analysis, and rigorous dynamic and cycle testing, the 170-12647 rotor hat is built to perform reliably in demanding high-performance and motorsport braking applications.

I like how autoplicty puts listing on ebay so you have more options for cheaper prices.

OK, but shipping cost not determined until after processing to paypal.

Ordering was easy, over the phone or online i was able to find all my parts on Autoplicity conveniently and my order was shipped out in a timely manner. I had concerns that were tended to by a quick phone call and great customer services reps.

Fantastic service and fast shipping! Lowest price on the net for the CAI that I bought!<br><br>This is my new "Go To" website for parts.<br><br>Thanks!

First time customer. To order is simple enough, looking for a good experience.

Good price, great presentation and easy navigation.

I thought there was a 5% off by signing up at the beginning. It went away and I didn't get it. I may be wrong.
