Hardrace Front Upper Arm Camber Kit – Honda S2000 AP1 / AP2

Hardrace Front Upper Arm Camber Kit – Honda S2000 AP1 / AP2 (7269)

Product Overview

The Honda S2000 is revered worldwide for its near-perfect front-to-rear weight distribution and ultra-responsive double-wishbone front suspension layout. However, when the chassis is lowered on performance springs or track-oriented coilovers, the factory geometry forces an aggressive shift into negative camber. Because the original front upper control arms are non-adjustable components, you are severely restricted from dialing in the precise camber parameters needed to balance front tire adhesion or cure inner tire wear during aggressive driving.

The Hardrace Front Upper Arm Camber Kit (7269) is a premium adjustable suspension solution engineered to optimize your front-axle geometry. Available at JDMaster.net, this heavy-duty 2-piece control arm kit replaces your fixed factory front upper links with a highly adjustable, turnbuckle-style assembly. Pre-installed with motorsport-grade spherical pillow ball bushings, this kit completely eradicates suspension pivot flex under high-braking and high-G cornering loads, giving you the power to fine-tune your alignment lines for maximum steering wheel precision.

Key Features & Benefits

• Continuous Turnbuckle Camber Adjustment: Features an integrated heavy-duty threaded turnbuckle collar system that allows for continuous, on-car length calibration to easily correct or increase front camber.

• Motorsport Spherical Pillow Balls: Pre-assembled with zero-tolerance, high-hardness spherical metal joints protected by integrated weather-proof anti-dust boots. They completely eliminate the soft compliance lag of factory rubber.

• Sharper Driver Feedback: Removing isolated flex inside the upper pivot structure establishes a direct pathway from your subframe to the knuckles, delivering telepathic steering response and real-time tire communication.

• Heavy-Duty Gusseted Steel Structure: Fabricated from high-tensile, heavy-gauge steel tubing and plates with extensive perimeter stitch-welding to withstand heavy curb impacts and intense braking forces.

• Optimizes Front Tire Footprint: Allows you to adjust front wheel angles back to factory lines for uniform everyday road tread wear, or optimize them for flat-foot track tracking through high-speed trail-braking zones.

• Premium ED Anti-Corrosion Defense: Treated with Hardrace’s proprietary Electrophoretic Deposition (ED) base coating and industrial paint layers to resist moisture, dirt, and stone chips.

• Direct Bolt-On Configuration: Engineered using precise physical 3D modeling to ensure a perfect drop-in fit with your original front crossmember subframe pickup points and upper knuckle ball joints.

Technical Specifications

Applications

This precision-engineered adjustable front upper control arm package features precise physical dimensions engineered to service all model years of Honda’s premier RWD roadster platform:

• Honda S2000 AP1 (1999–2003 Models — F20C)

• Honda S2000 AP2 (2004–2009 Models — F22C1)

The Mechanical Advantage: Taming Lowered S2000 Front Geometry

The short-arm/long-arm double-wishbone suspension of the S2000 relies heavily on the upper control arm to dictate the wheel’s camber gain arc during suspension compression and cornering. When you lower the vehicle’s ride height, the front upper arm tilts upward into a tighter resting angle, drawing the top of the hub knuckle inward. Because the factory lower eccentric alignment bolts offer narrow operational boundaries, standard adjustment methods fail to provide the necessary range to achieve an aggressive track-oriented setting or correct extreme static negative camber.

The Hardrace 7269 adjustable front upper arms solve this physical restriction entirely. By turning the high-strength turnbuckle sleeve, your alignment technician can smoothly push or pull the top of the knuckle, restoring a full, flat tire contact patch or adjusting for maximum turn-in bite. Furthermore, because factory rubber bushings act like soft compliance springs that distort under pressure, upgrading to zero-clearance spherical pillow balls locks out side-to-side squirm. The result is total authority over your tire wear, increased stability under heavy braking, and an exceptionally predictable steering feel.

Professional Lift Installation & Alignment Notes

🔧 Important Technical Fitting Note: Adjusting these front upper control arms alters your front camber, track width, steering caster tracking, and toe parameters simultaneously, a comprehensive professional four-wheel laser alignment is strictly mandatory immediately following installation. You can arrange a precision setup session at our fully equipped JDMaster.net workshop, where our technicians specialize in high-precision suspension indexing, geometry correction, and custom track-oriented alignment profiling.

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.
