Product Details

The Wilwood 170-0357 is an HD Series Fixed Mount Disc Brake Rotor Hat designed for rear drag racing applications, featuring a 1.77" offset. Manufactured from premium-grade aluminum alloy, this rotor hat delivers an exceptional combination of high strength, low weight, and competition-ready quality.

Key Features:

  • Premium aluminum alloy construction — delivers high strength with minimal weight penalty
  • Straight bell design with a flanged rotor mount ring for solid, reliable rotor retention
  • Threaded-hole rotor mounts for use with through-hole rotors and matching Wilwood rotor hardware
  • Maximum radial clearance between the caliper body and hat — essential when fitting large calipers inside smaller wheels
  • 1.77" offset tailored for rear drag brake configurations
  • Compatible with a wide range of applications, from OE four-lug axle shafts to Grand National stock car racing hubs
  • Suitable for custom axle builds and competition disc brake conversions

The Wilwood HD Series rotor hat has been a proven component in Wilwood's racing disc brake conversion kits for years. When paired with matching Wilwood rotor hardware and fasteners, the 170-0357 provides a rigid, dependable mounting platform for custom and competition brake systems across a broad range of motorsport and performance applications.

so far so good!

Not only was it the cheapest price, but they had the fastest and lowest price shipping, and best customer service. Thanks Autoplicity!

Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.

Not only were they the cheapest price on the web, they shipped out my item the next day!<br><br>Thank you Autoplicity!<br><br>I'll definitely use you again/

Great prices and fast shipping! What more could you ask for?

Good service, fast shipping, excellent prices
