Subaru Impreza WRX 14+ Rear Trailling Arms [MR] It is within this understanding that Megan Racing has unveiled our line of reinforced suspension arms that offer the strength and adjustment that any competition vehicle will ever need. Constructed of high-strength steel alloys that offer durability, strength and yet remain light-weight, these control arms have been track tested for months in road race, autocross and drift events to assure quality and performance. The main benefit of the Pillow-Ball Trailing Arms is to induce a more Direct-Feel and stability of vehicle. OEM rear-end is softer due to the conservative soft-rubber bushings that absorb vibration and road noise. The Anti-Dust Pillowball ends eliminate that "soggy" feel and allow for a more stable direct feel that the performance-oriented driver prefers. The steel construction makes these Trailing arms much stronger than stock and allow them to be used in competition where they will see extreme conditions and loads. Applications: - Subaru Impreza 12+ /Forester 14+ - Constructed of Steel Alloy for Lightweight yet Durable performance. - Eliminates Premature Tire Wear while improving handling and stability. - Pillow Ball construction
