DBA 4000 Series T3 Front Slotted Brake Rotor DBA42398S - 1997-2009 Porsche Boxster

DBA 4000 Series T3 front brake rotor for the 1997-2009 Porsche Boxster. The T3 T-Slot pattern is uni-directional and sweeps gas and pad dust off the friction face under repeated hard braking.

• Position: Front axle
• 4000 Series T3 T-Slot uni-directional slotted design
• Slotted face only, no cross-drilling
• Uni-directional vane layout, so left and right sides are specific
• Manufacturer part number: DBA42398S

Because the rotor is uni-directional, check which side you need before ordering.

Fits 1997-2009 Porsche Boxster. The Boxster used more than one front brake package across this span, so confirm fitment by year, trim, and brake package before ordering.

Replace rotors in pairs across an axle so braking stays even from side to side. Remove the protective shipping coating from the friction faces before install, and make sure the hub face is clean and free of rust so the rotor seats flat and runs true.

The machined face pattern is designed to vent gas and pad dust away from the friction surface, which keeps bite consistent once the brakes are hot. Bed the new rotors and pads in together with a series of moderate stops before driving hard, and expect light face shading afterward.
