Turbo Groove automotive brake discs have a widened, arcuate slit that increases the flow of cool air, lowering the temperature of the brake pads and disc, while draining dust, dirt and hot gases better than a straight line, which can rust and become ineffective. Drilled holes remove surface gases when braking from high speed, while not weakening the structure of the disc as in through drilling. TECHNICAL DATA Type: Drilled and Slotted Full / Ventilated: Full Number of holes: 4 Diameter (mm): 252 Height (mm): 34 Thickness (mm): 9 Minimum thickness (mm): 8 Axle application: Rear APPLICATION Brand Model Engine Value Power (KM) Year MAZDA 323 1.8 GTI 89-94 MAZDA 323 1.8 TURBO 165 90-94 MAZDA 323 1.8 TURBO GTX 185 89-94 MAZDA MX3 1.6 91-97 MAZDA MX3 1.8 91-97 MAZDA MX5 (MK1) (NA) 1.8 94-98 MAZDA MX5 (MK2) (NB) 1.6 98-2005 MAZDA MX5 (MK2) (NB) 1.8 98-2005
