• Direct bolt-on installation

2003 GD WRX Platform
The 2003 GD WRX is the first production year of the GD chassis in North America. Factory suspension is capable but conservatively calibrated for a broad range of drivers. Whiteline’s Grip Series kit addresses all three major suspension improvement areas — center of gravity, roll stiffness, and bar geometry — in a validated, matched package.

Matched and Validated
Spring rates, bar diameters, and endlink geometry are all matched for the 2003 GD WRX platform. The components work together rather than as individually-sourced parts.

Adjustable for Your Use
Both adjustable bars allow fine-tuning the front-rear balance for street, autocross, or track use.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.

The RallySport Take

The complete suspension improvement for the first-year GD WRX. Get an alignment after installation — lowering changes geometry and the car won’t handle correctly without a proper four-wheel alignment at the new ride height. Combine with Whiteline’s roll center correction kit if the car uses MacPherson strut front suspension.
