BMW F20 F21 F22 F23 F30 F31 F32 F33 F36 Rear ARB Bush 14mm PFR5-1913-14

Powerflex PFR5-1913-14 rear anti-roll bar bushes for 14mm BMW rear ARBs - a fast-road and track-day upgrade that ditches rubber flex without going full race-spec. Fits all listed F-series chassis exactly as specified: no guesswork, no adapters.

• Direct fit for OEM part 33556853475 - replaces worn rubber with polyurethane for sharper turn-in and less rear squat
• Stiffer than stock, more compliant than hardcore compounds - ideal for daily drivers who also enjoy B-roads or the occasional track day
• Includes two bushes: everything needed for a complete rear ARB refresh
