Hardrace Rear Adjustable Lateral Arms – Subaru (6153-A)

Hardrace Rear Adjustable Lateral Arms – Subaru Impreza, Forester, Legacy (6153-A)

Product Overview

When early-generation Subarus are lowered on coilovers, the factory non-adjustable rear arms push past their designed operating angles. This pulls the rear track width inward and forces static negative camber that cannot be corrected with stock hardware. Available at JDMaster.net, this heavy-duty high-density steel kit swaps out all four factory rear lateral links (two front-lateral and two rear-lateral links per axle). Pre-installed with motorsport-grade spherical pillow ball bushings, the 6153-A kit eliminates rubber deflection, allowing you to dial in precise tracking, track width, camber, and toe settings to maximize your symmetrical AWD tire contact patch.

Key Features & Benefits

• 8-Piece Lateral Link Kit: Replaces all four rear lateral links across the rear axle (two forward-lateral links and two rearward-lateral links) for comprehensive horizontal alignment mastery.

• Zero-Deflection Pillow Balls: Pre-assembled with professional anti-dust spherical metal joints. By completely removing the elastic “squish” of aging OEM rubber, your alignment stays perfectly fixed even under severe cornering loads.

• Camber & Toe Adjustability: Features robust, on-car adjustable threaded sleeves that let your alignment technician correct geometry variations caused by aggressive lowering.

• High-Tensile Reinforced Steel Construction: Built from premium-grade tubular steel designed to survive heavy track curbing, aggressive drift transitions, and rugged rally stages without bending.

• Eliminates “Rear End Steer”: By removing soft rubber from the horizontal axis, the rear tires stay perfectly true to your steering inputs, completely removing unpredictable high-speed tail wag.

• Anti-Rust Treatment: Finished with Hardrace’s signature Electrophoretic Deposition (ED) coating to insulate the steel against salt, moisture, and road debris.

• Bolt-On OE Replacement: Manufactured to strict factory physical dimensions, integrating seamlessly with original rear knuckles, subframes, and performance coilovers.

Technical Specifications

Applications

The 8-piece 6153-A lateral link set matches the hub-to-subframe geometry across early independent multi-link Subaru architectures:

• Subaru Impreza WRX & STI (1st Gen) — 1992–2000 (GC / GF / GM Chassis)

• Subaru Impreza WRX & STI (2nd Gen) — 2001–2006 (GD / GG Chassis — Fits non-STI wide track models)

• Subaru Forester (1st Gen) — 1997–2002 (SF Chassis)

• Subaru Forester (2nd Gen) — 2003–2008 (SG Chassis)

• Subaru Legacy / Outback (2nd Gen) — 1995–1998 (BD / BG / BK Chassis)

Mechanics Corner: Why Choose the 8-Piece 6153-A Over Standard Arms?

The 6153-A kit specifically addresses the horizontal axis of your rear geometry. When cornering hard on factory rubber bushings, lateral loads force the rubber to compress, causing un-commanded dynamic toe and camber changes in the middle of a turn. This behavior is what makes early chassis types feel twitchy at the absolute limit.

By upgrading to the Hardrace 8-piece kit, you are replacing the flexible connections with solid metal spherical joints. Since the pillow balls pivot smoothly without binding or changing shape under pressure, your dynamic alignment settings remain entirely consistent. Whether you are correcting tire wear on a street-driven vehicle or seeking millimetric accuracy for track work, this kit ensures that your setup behaves identically during compression, rebound, and lateral transitions.

Professional Fitting & Alignment Notes

The Hardrace 6153-A kit utilizes solid metal spherical pillow balls instead of soft rubber. While this yields maximum performance, it will transfer a higher level of mechanical road noise, harshness, and tire vibration into the cabin. This is a normal consequence of a track-oriented chassis configuration.

Because modifying these lateral links alters your rear track width, camber, and toe settings simultaneously, a professional four-wheel laser alignment is strictly required after installation. You can schedule a tailored setup at our JDMaster.net workshop, where our mechanics align suspension configurations for street, circuit racing, and rally environments.

Warranty

The warranty on Hardrace products depends on the type of product, with a minimum warranty period of 2 years. This warranty does not cover damage caused by a car crash, improper use, negligence or normal wear and tear.
