SMY Stealth Pillow Ball CNC Aluminum Adjustable Rear Control Arm / Toe Kit Subaru 2022-2026 WRX

Take absolute, 360-degree control over your rear suspension geometry. Lowering your WRX, STI, or BRZ on Coilovers or lowering springs introduces a double-whammy of alignment issues: aggressive negative camber and severely distorted toe angles. Standard OEM arms completely lack the adjustability to correct this, leaving you stuck with ruined tires, reduced straight-line traction, and unpredictable rear-end handling. The SMY Performance Stealth Complete Rear Alignment Kit is the ultimate all-in-one professional solution. By pairing our ultra-rigid CNC-machined lower control arms with matching high-tensile adjustable toe arms, this kit gives alignment technicians the total freedom needed to dial in a flawless, square footprint—whether you are setting up a daily driver for maximum tire longevity or prepping a track weapon for maximum cornering grip.

Features:
- Total Alignment Correction (Camber + Toe): Adjusting rear camber naturally alters your toe setting. Attempting to fix camber without adjustable toe arms forces your car into an unequal alignment that causes "crab-walking" and rapid tire scrubbing. This master kit resolves both sides of the equation simultaneously, ensuring your wheels track perfectly straight under hard acceleration and heavy braking.
- Engineered for Pure Strength (Anti-Break Architecture): Many aftermarket control arms on the market cut corners with thin, hollow profiles or brittle castings that flex under load and are notoriously prone to snapping or buckling on track. SMY components are over-engineered with an ultra-rigid, structurally reinforced geometric profile that eliminates deflection entirely. They are built to take a beating, guaranteeing they will never bend or break.
- The Billet Aluminum Advantage vs. Competitor Steel: Traditional aftermarket brands like Whiteline, Cusco, SuperPro, and SPC rely on heavy, stamped or tubular steel configurations. Choosing SMY's premium CNC-machined billet aluminum kit over their steel alternatives unlocks massive performance advantages:
     1- Zero Welds to Fail: Steel arms rely on welded joints at the high-stress end bungs, creating inherent weak points. SMY lower control arms are carved from a single, solid piece of aluminum with zero welds to crack or fail under hard cornering.
     2- 100% Corrosion Proof: Steel arms inevitably chip, scratch, and rust when exposed to road salt and moisture, causing adjustment threads to seize. Aluminum naturally resists rust and atmospheric degradation, ensuring smooth adjustability for the life of the vehicle.
     3- Massive Unsprang Weight Reduction: Aluminum delivers a vastly superior strength-to-weight ratio compared to steel, pulling unnecessary weight away from your wheel hubs.
- Faster Suspension Articulation: By stripping heavy unsprang mass from your rear suspension, your shocks can react instantly to changes in the road surface. This keeps your tires glued to the pavement, massively improving mid-corner tracking and overall ride quality.
- Upgraded 80-Durometer Comfort Pillow ball Ends: Avoid the harsh, noisy metal-on-metal rattling common with cheap, track-only arms. SMY features thicker, heavily reinforced 80-durometer performance bushings designed to maximize cornering response and durability while dampening the harsh road noise and high-frequency vibrations that ruin street driving comfort.

Installation:
- Control Arm Endlink Bolts: 34 ft-lbs.
- Control Arm Chassis/Hub Points (All 3): 89 ft-lbs.
- Toe Arms Subframe Side: 74 Foot-lbs.
- Toe Arms Other End: 44 Foot-lbs.
- Alignment is highly Recommended after installation
- Note: To ensure flawless bushing longevity and accurate geometry, always torque down suspension components while the vehicle is resting under its full weight on the ground (loaded), never while suspended in the air.
-  Lowering your car without adjusting your camber is a recipe for burning through expensive sets of tires. Don't risk your safety on cheap, un-structured arms that can snap mid-corner, or heavy steel arms that rust out. These lightweight, solid CNC aluminum arms pay for themselves by flattening out your tire wear, maximizing your chassis rigidity, and permanently upgrading your rear-end control.
