The new version of the e36-e46 (non ///M) 332x32mm kit uses an entirely new fully floating system, that improves it’s functionality and strength, yet is totally quiet for street use. The floating system uses drive-pins that are CNC'ed from 303 stainless steel. The pins allow for expansion and contraction of the rotors, which helps eliminate pulsations and vibrations, while the aluminum hat reduces heat transfer. The Calipers used in the e36-46 kit are Wilwood's radially mounted SL6R or SL4R units (BMWCCA CR Prepared class limits calipers to 4 pistons). These calipers accept thick 21mm pads in a popular size that Carbotech, Performance Friction, Ferrodo, Hawk, and others produce at lower prices then the OEM fitment pad. Kits include Wilwood BP20 pads, but kits include the option to upgrade to other pads. (brake lines not shown).

The beefy brake rotors are machined to our exact specification here in the USA. We have them machined with a heavy wall thickness of over 8mm, which significantly cuts down on rotor cracking and extends their service life. We are offering them in both slotted and blank form. Blank rotors provide the maximum contact surface with the pad possible, and consume less pad material compared to slotted rotors. We do not offer performance kits with drilled rotors. Our replacement rotors are priced significantly lower than other kits that require the replacement of the entire floating hat (Motorsport floating rotor), or from companies that make their profits from the sale of expensive, branded consumables.
