BLOX Racing 2015-2021 Subaru WRX STi Pitch Stop Brace
BLOX Racing Pitch Stop Brace BXSS-50100 is CNC-machined from billet aluminum to reinforce the weak OEM mounting brackets on 2015-2021 Subaru WRX and STi models. These vehicles suffer from thin brackets that bend or tear under engine pitch during normal driving. The brace ties brackets to the firewall cutting flex and doubling as a clutch master cylinder brace for sharper response.
