Balance measured, not guessed

Two cars with identical parts can behave completely differently on track, and the reason is usually setup, not hardware. Weight that sits unevenly across the four corners makes a car grip harder in one direction than the other, so it rotates beautifully into a left-hander and pushes wide into a right. You feel it as inconsistency, and inconsistency costs confidence and time.

At XTC Motorsport we measure that balance instead of guessing at it. Corner weighting and laser alignment turn vague handling complaints into numbers we can adjust, so the car you hand back behaves the same way in every corner. This is the quiet work that makes everything else, your tyres, your coilovers, your driving, actually pay off.

Corner weighting measured to the gram

Corner weighting puts each wheel on its own scale and adjusts spring perches until the diagonal weight, the cross-weight, is balanced for your car. We set it with you, your fuel load and ballast representative of how the car runs, because a car balanced empty in the workshop won't be balanced with a driver aboard. The target is a cross-weight near fifty percent so grip is even left to right.

On adjustable suspension this is precise work measured to the gram, and small perch changes make a real difference to how the car turns. We document the starting figures and the final result so you can see exactly what changed and why.

Laser geometry set to a target spec

Alignment is where camber, toe and caster decide how your tyres meet the road. We laser-align to a target spec built around your tyre, your camber curve and whether you want stability or sharper turn-in, rather than defaulting to factory numbers meant for tyre life and a smooth ride.

• Four-wheel corner weighting with driver weight and fuel accounted for
• Cross-weight set toward a balanced fifty percent target
• Laser-measured camber, toe and caster on all four corners
• Geometry tuned to your tyre and desired balance, not factory defaults
• Ride height confirmed and equalised side to side
• Full before-and-after setup sheet for your records

Repeatable, documented, yours to keep

Every session ends with a setup sheet recording corner weights, ride heights and alignment figures. That sheet is your baseline: it lets us return the car to a known-good state, compare changes lap to lap, and chase improvements methodically instead of by feel. It also travels with the car if you change tyres or adjust your suspension later.

If your car feels different turning one way versus the other, the answer is on the scales and in the geometry, not in your head. Reserve a corner-weight and alignment session tuned to your setup sheet and get balance you can measure.
