Subaru WRX STI 2004-2007 316x20mm Rear Brake Discs for track-focused road cars. Two-piece floating brake disc construction helps manage heat, reduce fade, and improve braking consistency under repeated hard use.
Made to order. Production and dispatch usually take about 30 days from order confirmation.
Brake disc measurement: 316×20mm rear, matched to the 2004-2007 WRX STI’s front discs for balanced AWD braking.
Two-piece floating construction: an aluminium bell decoupled from a high-carbon cast iron friction ring, cutting unsprung weight and letting the disc expand under heat without warping.
Built for the WRX STI’s typical use case: fast-road and track-day driving, where the factory disc is prone to fade after repeated hard stops.
Pairs with OEM-fitment WRX STI rear calipers, no bracket or caliper swap needed on a stock car.
Fits the Subaru WRX STI from the 2004-2007 model years with the factory rear brake package. Always confirm your exact caliper part number and disc bell diameter before ordering, since brake specs vary across model years, and we want to get this right the first time.
