Product Description

StopTech high quality cross drilled rotors are a direct replacement for your vehicle. 128.34093 fits BMW E90 3-Series.

StopTech Sport Drilled Rotors are high quality ;cross drilled, one-piece, direct replacement brake rotors used with your factory brake system. StopTech Sport Drilled Rotors prevent glazing of the pads, add bite and improve wet and dry braking performance. Each StopTech sport Slotted Rotor is produced using a high quality StopTech Premium Rotor, featuring electro-coating, Double Disc Ground, Machined Finishes, Split Castings and Mill Balancing.

Directional Drilled Friction Surface:

StopTech Sport Drilled Rotors have a unique cross drilled pattern for the left and right sides of the vehicle. For these directional friction surfaces, straight or pillar internal cooling vane rotors are used for maximum performance and to ensure that a drilled hole never touches a cooling vane.

Electro-Coating:

StopTech electro-coating

StopTech Sport Drilled Rotors utilize an Electro-Coating finish that provides long lasting corrosion protection. Electro-Coating is an electrostatically applied finish that is designed to withstand 400 hours of salt-water exposure without rusting.

Double Disc Ground:

StopTech double disc ground

StopTech Sport Drilled Rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad-rotor break in. This finish also provides quieter and smoother stops.

Mill Balanced and Machined Finishing:

StopTech machined finishes

StopTech Sport Drilled Rotors feature 100% fully machined finishes, including rotor hats. In addition, StopTech Sport Drilled Rotors are also inspected for balancing and mill-corrected to a tolerance of less than 2 oz. per inch. This extra process provides better rotor balancing and creates a cleaner, more professional looking component.

Center Split Casting:

StopTech split casting

Center-split core castings provide uniform heat transfer and thermal efficiency from the friction plates into the cooling vanes, resulting in superior braking power and safety. Competitors' vanes are often asymmetrical, which can lead to uneven heat transfer and compromises in performance and cooling.

Original Vane Structure:

StopTech-original-vane-structure

StopTech Sport Drilled Rotors feature O.E. style internal vane designs. This attention to detail ensures each StopTech Sport Drilled Rotor will function just like the original part.

Ordering Information:
StopTech Rotors are priced and sold individually on our website.

* While the required rotor diameter can be determined based on your VIN number, many cars now have different sized rotors fitted by mechanics than what the car was originally fitted with. As such, we advise that you physically measure the brake rotor diameter to determine your correct rotor size prior to ordering.
