Will fit: OE SLOTTED & PLATED FRONT brake rotors for E90/E92/E93 335i, 335Xi, 335d Slots are stress-relieved, do not extend through to edge of rotor. Directional slotting for improved effectiveness and aesthetics. Minimum thickness markings on every rotor for quick maintenance checks. Correct retaining screw position. Heat dam provides maximum protection from heat transfer to wheel hub. What makes the best brake rotors? Details, details, details, and value! UUC Ultimate OE-size replacement rotors are slotted, plated, and manufactured using the best techniques and materials. Optional Slotting: there are many reasons to slot rotors. Primarily, slotting aids in removal of water and debris on the rotor surface, evacuation of hot pad "off gassing" vapor, and provides a visual wear indicator. Details: These slots do not extend all the way to the edge of the rotor for a very specific reason; this maintains the structural integrity of the rotor. Other brands with slots all the way to the end have created "stress risers" where cracking may develop. No such problem exists with this design. Additionally, directional slotting enhances effectiveness. NO DRILLING! Drilled holes in rotors often used for "show" are prone to cracking and catastrophic failure. The holes create stress risers which will lead to this sort of failure. Additionally, drilled holes do not improve cooling, rotary-vane rotors lose efficiency when drilled because cooling air does not not pass through the rotor circumferentially but is instead prematurely evacuated by the holes.. Plating: Multi-stage black plating resists unsightly corrosion on the rotor hub and unswept areas of the rotor face. Rotor after normal use, normal silver color in swept area. Precision: due to the ultra-precise tolerances used for run-out, parallelism, and surface flatness, absolutely no pre-installation machining is required for smooth operation without vibration or shimmy. Manufacturing details: Meets SAE standards for brake rotor iron. Alloying: Copper and Chromium added to achieve specific hardness and tensile strength. Precision-controlled cooling during the casting process creates a uniform distribution of graphite flakes, thus increasing wear resistance and the ability to dissipate heat. In contrast, premature cooling of cast iron can cause iron brittleness, thus making the brake rotor more likely to warp or crack, especially when overheated under hard braking conditions. Run-out less than .004". Parallelism of machined surfaces within .0005" tolerance. This attention to detail makes these rotors suitable for street, auto-x, track, and race use. These are current in the south island (Dunedin) but can ship NZ wide. $450 NZD. Brand New. I can supply ceramic HAWK pads at a good price if you like, or any other supporting mods like braided lines etc. Also those who know .. can bring in other items from the states. Heavy/Bulky by sea, light/small by air. Over the past few orders, have learnt which suppliers are the ones to use, PM me if you want to get some parts in.
