Whiteline Rear Bump Steer Correction Kit – 2003-2006 Mitsubishi Evo 8/9

Whiteline Rear Bump Steer Correction Kit – 2003-2006 Mitsubishi Evo 8/9

Eliminate Rear Bump Steer on Your Evo 8 or 9
When the Evo 8/9 is lowered, the rear suspension geometry changes in ways that introduce rear bump steer — the rear wheels toe in and out through suspension travel rather than tracking straight. Whiteline’s Rear Bump Steer Correction Kit uses offset adjustment to correct the geometry at the lateral link position, restoring designed rear wheel tracking through suspension travel and producing a more predictable, stable rear axle on lowered Evo applications.

DETAILS

• Corrects rear bump steer caused by lowering on Evo 8/9 platform
• Offset geometry restores designed rear wheel tracking through suspension travel
• Polyurethane bushings for precise geometry maintenance
• Fitment: 2003-2006 Mitsubishi Lancer Evolution VIII and IX
• Direct bolt-in — no chassis modification required

What Rear Bump Steer Does to Handling
Rear bump steer means the rear wheels change toe angle as the suspension compresses and extends. Under normal driving, this introduces a slight weave sensation. Over bumps in corners — which is when you most want the rear wheels tracking precisely — bump steer causes the rear to step out or tuck in unexpectedly. On a lowered Evo used for track driving, this is a real problem that directly affects handling consistency.

Why Lowering Causes Bump Steer
The Evo 8/9 rear geometry was designed to operate within the factory ride height range. When the car is lowered, the angles between the lateral links and the hub carrier change, and the bump steer curve shifts. The correction kit reestablishes the correct angle at the lateral link pivot, restoring the designed zero bump steer behavior at the new ride height.

Evo 8/9 Track Application
The Evo 8 and 9 are serious track platforms used in time attack and circuit competition. Rear bump steer is a performance limitation that needs to be addressed on any lowered Evo used seriously. This kit is a standard recommendation for lowered Evo track builds.

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

A technically important geometry correction for any lowered Evo 8 or 9. The improvement in rear axle tracking consistency is real and directly improves lap time predictability. Get an alignment after installation — the offset geometry changes the static alignment readings. The improvement in steering feel and braking stability is noticeable immediately. Combine with a matching rear anti-lift or geometry correction kit for the most complete front end precision package.
