Description
Each disc is a two-piece build. A ventilated iron ring rides on floating bobbins and bolts to a black anodised aluminium hat. The faces are slotted, not cross-drilled. The part codes read F15OERP390B front and R15OERP380BD rear; OERP is Neotech’s designation for an OE Replacement Performance disc, so these run behind the factory Brembo calipers without adapters.
Check the sizes first. 390 mm front with 380 mm rear is the 2012-on R35 specification, so a 2007 to 2011 car needs the 380 mm front instead.
Neotech publishes its own tolerances: thickness variation under 0.02 mm, runout under 0.03 mm, weight balance within 10 g. We supply and fit these at Bandar Sunway as Neotech’s Malaysia distributor.
