Thank you. You have rated this product.

Weight in the wheels and brakes is where it matters most, this is where every pound saved makes a difference. Improve both ride quality and performance all at once with our lightweight rotors! 2-piece rear rotor upgrade in the same size as the 11" factory rear rotor for a "drop in" fit. These rotors work with the factory rear calipers.

Plain and slotted rotor styles saves 1 lb per side compared to the stock rear rotor. Wave rotor style saves 2.5 lbs per side! Wave rotors are commonly found on motorcycles where weight savings is paramount. Our wave rotors function like stock but weigh much less! 

This kit is centered around lightweight aluminum hats built for us by Wilwood. Uses a premium grade iron friction ring. Hardware included.

* Reduced rotational mass
* Affordable rotor replacements
* More thermally stable 2-piece design resists warp/flex and brake drag under high heat much better than solid 1-piece rotors

Price is for TWO rotor/hat assemblies.

These friction rings are MADE TO ORDER - allow 2-3 weeks from time of order.

INSTALL NOTES: Minor grinding of the factory brake caliper's bracket is needed for clearance between the bolt heads on the back of this rotor and the caliper bracket.

Roadstersport II was a great purchase, easy install, and sounds great.

Hi Brian, I just bought a heatshield and a cruise control relocation bracket for my '95 Miata from you. It is in the mail now. Thanks for such fast service. (My cruise is just wrapped up in a microfiber shoprag at this time!)
