NOTE: This is an oversized rotor kit for a single sided brake set up and will require the installation of the included brake caliper spacers. If you do not own a single sided brake conversion kit, here are two options: Stage 1 or Stage 2.
The BrakeTech AXIS RR series extreme performance Iron rotors are designed for the demanding enthusiasts and racers alike! The rotors feature premium heat-treated iron in a optimized petal design that offers style and performance with none of the downside associated with exaggerated wave type rotors. The patented AXIS Design bristles with many new and innovative features making them substantially stronger and with much improved thermal transfer capabilities than any other competitive brand. All of the considerable braking forces are channeled through the trademarked Direct-Link architecture, comprising over an 800% increase in surface area load transfer as compared to conventional floating brake rotors…simply far superior by design!

Sintered Metal Brake Pads on Iron?
There does indeed exist a universal prohibition against the use of sintered metal pads on generic cast iron rotors, we have the same warning. But this caveat is more specifically targeted to old-school gray cast iron and particularly of the individual molding, gravity feed casting type. That combination was and is inherently problematic with a propensity towards suffering from thermal stress induced fracturing. Not good. The AXIS/Iron on the other hand is a significantly different animal. Firstly, it is CNC machined from American made high grade nodular ductile iron, not gray iron. Secondly, it’s a genuine billet part, sawed from continuous cast bar (which eliminates porosity and the problems associated with that). Thirdly, it is an inherently stronger material with tensile strength more akin to steel than gray iron. Plus, besides traditional heat-treat, we also Cryogenically process them to improve their abrasion resistance and reduce wear. But bear in mind, they are still “softer” than stainless steel, which simply stated means you cannot run any pad you want without the potential for problems developing.
Recommended pad material is Organic/Semi-Metallic, Sintered or Carbon Ceramic. Though along with virtually all sintered metal formulations, they will likely result in a somewhat shortened rotor life compared to the organic alternative.
