Caster describes how far the tyre contact patch trails the imaginary steering axis. It is what pulls the wheel back to straight ahead while driving. Your Land Rover leaves the factory with 3° of caster. A suspension lift makes the steering axis steeper and reduces the caster, so straight-line stability and the self-centering of the steering deteriorate and the vehicle feels nervous.

The innovative axle widening kit for your Land Rover
More performance. Less load. Unchanged steering geometry.
The secret is where it sits. Widetrack widens the track between the axle
and the swivel ball, not with a plate behind the wheel like conventional
wheel spacers.
More than just
track widening
Our job at Widetrack is to get the best out of your vehicle. With integrated caster correction and the original scrub radius, we offer not just a track widening kit but a complete system with real handling benefits, without trading them for drawbacks elsewhere.

How our caster correction works
Our axle widening kit corrects this by rotating the swivel housing by up to 4° relative to the axle. That restores the original caster angle, or deliberately over-corrects it for even better straight-line stability than in standard trim.
Which caster correction
is right for you?
For standard ride height up to +30 mm, trials & competition
Caster correction 2°
Our recommendation at original ride height, and for trials and competition vehicles that do not need pronounced straight-line stability.
For lifted suspension
Caster correction 4°
Our recommendation for all other vehicles, especially with a 40–60 mm lift: brings the caster back into the optimum range for solid straight-line stability and calm handling.
Small scrub radius
Conventional wheel spacers increase the scrub radius and with it the lever arm through which the wheel forces act on the steering. The result is more nervous handling, poorer tracking, and higher loads and wear on the steering and bearings.
Our system widens the track without changing the original steering geometry or the scrub radius. Precise steering and straight-line stability are preserved, while the load on the steering and bearings is significantly lower than with conventional wheel spacers.
Unlike wheel spacers, the axle widening kit does not alter the steering kinematics. The scrub radius stays original, so despite the wider track, the reduced tendency to tip and the better looks, nothing changes in the steering behaviour or in the forces acting on the suspension. Wheel spacers, on the other hand, increase the scrub radius at the front axle, which leads to poorer tracking and considerably higher loads on the wheel bearings, swivel bearings and steering box, and can cause these components to fail prematurely.
More benefits at a glance
Less kickback through the steering
Impacts on the wheel have far less effect on the steering, so less of the terrain reaches the steering wheel.
Less load on the wheel bearings
No additional leverage from bolt-on wheel spacers: the wheel bearings work exactly as they were designed to.
Protected swivel pin bearings
The swivel pin bearings also carry far less load than with wheel spacers. No compromise on the service life of your axle.
Scrub radius as from the factory
The widening sits inboard at the axle, so the scrub radius is preserved exactly.
Selectable caster correction
Noticeably safer and better handling with improved straight-line stability.
Low-wear drivetrain
The 30 mm longer halfshafts in high-strength 34CrNiMo6 steel allow more torsional give and absorb more shocks and vibration from the drivetrain. That protects the gearbox, differential and drive flanges.
