Details
Yes with a spacer. This kit is one of the few big brake kits listed for the aluminum-knuckle 2022+ BRZ as well as the GR86. The vendor's guide says OEM 2022+ 17s and 18s need at least a 3 mm spacer, while its forum post says the BRZ's OEM 18 needs an 8 mm spacer; both come from the seller, so ask before ordering.
