The eccentric bushings in the rear upright also allow independent wheelbase adjustment. The height of front and rear axles can be easily adjusted with eccentric bushings.

Offset Adjustment.

Wheel offset is easily adjustable by 0.5–2.5mm using included shims. This affects steering adjustment (when adjusted at the front) and also rear traction characteristics (when adjusted at the rear).

FRONT - Less offset at the front gives more in-corner steering and improved steering response. Recommended for small technical tracks.

More offset at the front gives more stability and makes the car easier to drive on large tracks or under high-grip conditions.

REAR - Less offset at the rear gives more in-corner steering, but less rear traction and stability. Therefore it is recommended to use less offset on small technical tracks or under high-traction conditions.

More offset at the rear makes the car more stable and improves cornering speed.
