Thank you. You have rated this product.

The best replacement rotors for your MazdaSpeed3. The 4000 Series Wiper-Slot rotor has a unique 6x6 slotted design for extreme stopping power on the road and the track. These are directional rotors and each order is a matched PAIR of left and right.

As with every DBA rotor, the 4000 Series rotor bolts right onto the vehicle with no mechanical changes needed. DBA's enhanced-performance, slotted rotor features Thermal Stability Profiling (TSP) for improved heat handling and Thermo-Graphic paint markings for effective heat monitoring. Thermo-Graphic markings are placed on the outer edge of each DBA 4000 series disc rotors and are used to monitor the core temperatures achieved during braking application. The markings change color as the rotor heats up to alert the driver to rotor temperatures that exceed optimum levels.

The ''Kangaroo Paw'' design features a series of 144 diamond- and tear drop-shaped pillars and columns individually spaced between the rotor faces. This system provides two key advantages.

First, is the ability to cool the rotor faster than ever before. As the disc rotor rotates, aerodynamic turbulence around the individual pillars and columns is generated, increasing the force of hot air out from within the internal areas of the rotor.

Second is increased dimensional stability across the disc rotor directly achieved by the individually spaced pillars and columns. These advantages increase the disc rotor's efficiency by as much as 20% when compared to conventional rotor designs. A 20% increase in disc rotor efficiency directly translates to reduced brake operating temperatures, brake fade, disc rotor stresses, disc thickness variation, run-out and shudder.

All 4000 series rotors also benefit from DBA's "Longlife Slotted" design. The rotors are manufactured to QS-9000 quality standards using premium grade materials with a high iron content and dense metal matrix resulting in long wear and safe, consistent stopping power.

* Unidirectional slotting (left and right) increases pad bite, reduces fade and delivers exceptional braking performance.
* Slots continually de-glaze the brake pads improving efficiency and reducing rotor scoring.
* Slots even out wear across the brake pad faces, increasing the effective contact area and extending rotor life.
* Slots help dissipate water when driving in poor weather, as well as pump away dust and dirt.
* Slotting also combats "out-gassing," where gas (from the pad bonding agents) can form a cushion between pad and rotor, greatly reducing braking power. DBA rotors are chosen as Original Equipment on many vehicles.

REVIEWS

Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!

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!)
