But the factory geometry reflects road-car compromises that become real handling problems the moment you lower the car or take it to track.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront camber — Fixed at −0.8°:\u003c\/strong\u003e Not adjustable without aftermarket arms.

Verkline is the only manufacturer to have engineered both axles simultaneously in a single shared CAD model — clearances, bearing axes and adjustment ranges are guaranteed compatible by design, not assumed.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCNC-milled billet caster arm:\u003c\/strong\u003e Not a straight rod. The milled profile routes around the tie rod — collision risk eliminated by design. Bearing housing angled at 4° to keep the spherical bearing within its articulation range across full suspension travel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully independent adjustability:\u003c\/strong\u003e Caster 6°–10° and camber 2°–5° — each without affecting the other. Camber adjusted via the lower arm widens the track, reducing lateral load transfer — more grip from each tyre, not just more camber angle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear bump steer linearised:\u003c\/strong\u003e Camber and bump steer are fully decoupled. The rear bump steer curve is linearised — consistent, predictable toe change throughout full suspension travel regardless of camber setting.
