SPL Parts adjustable Rear Toe Arms (RTA) increase stability and response by eliminating bushing deflection while also offering a wide range of toe adjustment. Lowered BRZs, WRXs, and 86s need the adjustment range for correcting rear toe to ensure proper tire wear and handling. Correcting the static toe angle and eliminating the toe change that occurs due to bushing deflection makes a huge improvement to the overall driving experience of the car. Sharper turn-in, improved braking stability, and predictable handling from corner entry to corner exit.The SPL rear toe arms feature 360° clamps instead of jam nuts to make setting the toe angle significantly easier. Simply loosen the two 1/4"-20 titanium screws and turn the center arm to adjust the length. Tightening the screws locks down the arm and won't change your toe setting.OEM eccentric bolts are known to slip during hard cornering, altering your alignment settings and possibly ruining your track day. That's why we've paired the SPL eccentric lockouts and rear adjustable toe arm as a complete kit (RTAEL FRS).BenefitsLightweight: 2.48 lbs (1.13 kg) per Arm (23% Lighter than OEM)Large Toe Adjustability RangeEliminates Bushing Deflection and Toe Change due to DeflectionGreatly Improves Stability and Driving FeelEasier, On-Car Adjustment + No Jam NutsSelf-Cleaning, US Made, PTFE-Lined FK BearingsMaterialsHollow 6061-T6 Aluminum Arms (Anodized Black)6061-T6 Aluminum Spacers and 360º Clamps304 Stainless Steel Insert SpacersTi-6Al-4V Titanium 1/4-20 Socket Head Allen Screws (Anodized Blue)
