Condor Speed Shop’s stainless steel E46 brake cooling plates will simplify your race car build. Legal for Spec E46, they easily bolt in place of the stock brake dust shield. Pair them with 3″ ducting to route cool air from the front air dam to the center of the rotors. Condor Speed Shop also offers duct kits for E36s and E30s and offers a how-to-install video here. Neoprene ducting is available and listed separately, also from Condor Speed Shop. Sold as a pair for $110 at time of publication.
