SPL Parts Rear Toe Arms - 2022+ Subaru WRX

Choose between the regular Toe Arms and the Toe Arms with eccentric lockout kit.

SPL Rear Toe Arms for the 22+ Subaru WRX reduce some of the unwanted bumpsteer due to the compliant OEM rubber bushing deflecting. This gives a sharper, more responsive turn-in by increasing the yaw rate to help combat understeer while also giving a more linear, predictable handling behavior. For those lowering, or even raising your WRX, our arms also have a huge toe adjustability range needed to accomodate proper alignments.

Available to buy in combination with our eccentric lockout kit which deletes the OEM eccentric bolts, which are prone to slipping with aggressive driving and additional grip. This protects your alignment (and track days) from unwanted change due to bolt slip as a result.

For advanced setups, pairing our rear traction arms with our rear toe arms opens the door to making changes to the rear bumpsteer curve to dial-in the specific handling behavior you prefer: more rear steering to combat lazy turn-in, more neutrality to improve tire wear and stability, or simply retain the OEM behavior at most ride heights.

Key Features:

• Sharpened Response and Reduced Understeer
• Lightweight: 1.45 lbs (0.66 kg) per Side (25% Lighter than OEM)
• Improves Handling by Reducing Unwanted Toe Change
• Additional Bumpsteer Tuning (with RTR VB)
• Maintenance-Free, US Made, PTFE-Lined FK Bearings
• Eliminates Eccentric Bolt Slip and Resulting Alignment Change (with eccentric lockout kit only)

Materials

• 6061-T6 Hollow Aluminum Arm and 360° Clamps
• 304 Stainless Steel Spacers
• Ti-6Al-4V Titanium Hardware (Anodized Blue)

Easy, On-Car Adjustments

Simply loosen the 1/4"-20 titanium hardware and turn the arm to achieve the desired amount of camber. Lastly, tighten the 1/4"-20 titanium hardware to lock it in. No more wandering alignment specs as you try to hold one end and tighten the other.

Noise, Vibration, and Harshness (NVH)

The SPL rear toe arms are not a significant contributor to NVH. The minimal amount of road noise is appreciably dampened by the large OEM subframe bushings. If you've upgraded to solid subframe mounts then a small amount of road noise can be contributed, particularly over certain types of surfaces.

Replaces OEM Part Numbers

This is a list of known OEM part numbers. OEMs constantly make changes to part numbers due to part updates, suppliers, etc so this may not be a complete list.
