Product Details

The StopTech 120.42117 is a premium direct-replacement brake rotor engineered to meet or exceed OEM specifications. Part of StopTech's 120-series Premium Brake Rotor line, this rotor delivers reliable, consistent stopping performance for street-driven vehicles.

Key Features:

  • Black E-Coat Anti-Corrosion Finish — Electrostatically applied coating provides superior protection compared to standard phosphate or spray-paint finishes, rated to withstand 400+ hours of saltwater exposure
  • Symmetric Vane, Split-Core Casting — Promotes uniform heat distribution across the rotor face for consistent braking performance and reduced risk of warping
  • Double Disc Ground Friction Surface — Precision-machined contact surface ensures optimal pad break-in and maximizes service life
  • Floating Mounting Design — Allows for thermal expansion, reducing rotor distortion under repeated heavy braking
  • Direct OEM Replacement — Bolt-on fitment with no modifications required

StopTech is an ISO/TS 16949-certified manufacturer with a motorsport heritage, offering premium brake components trusted for both daily driving and performance applications. The 120.42117 is sold as a single rotor.

ordering was simple, paying was very quick and easy with amazon.

Great price & easy checkout

Great prices, super fast shipping!

Easy to find part and verify fit, price is low shipping not outrageous.

Until this it was pretty good. However I do not appreciate being forced to fill out this survey and add in information that I previously submitted....

Easy shopping thank you

easy website to maneuver

Great products and great prices all around.....just took lil longer than expected to process and ship

awesome just what I was looking for

I pieced a roof rack setup from all over the internet, and Autoplicity consistently beat every other vendor on price and shipping, even most auctions on eBay!<br>I found the site confusing when searching for items directly (why was the "Roof Racks & Cargo Carriers" dropdown empty, when Google showed their ads for tons of these products?). Since they always came up at the top of a Google Shopping search for products, using their website's internal navigation wasn't ever necessary.<br>Customer service guy was a little snippy, but I could have just been interrupting his lunch.

Quick and easy site to navigate!

Good prices and also discounted shipping sold me on it.
