Description - Vehicle: Ford RS200 (Group B 4WD / AWD) — mid-engine - Track: POWYS — Geufron Forest, Wales - Surface: Gravel (Medium / Wet, Heavy Rain) - Driving Style: Control / Stability-first (taming power-on oversteer) The RS200 is a mid-engine Group B rally legend — and notoriously twitchy on corner exit. In heavy rain on wet medium gravel (low grip), priority is keeping the tail planted rather than raw pace. This control-first setup biases torque to the front axle, opens the rear viscous diff, and adds rear toe-in so the car tracks straight under power instead of stepping out.

Key Characteristics: 1. Alignment:+0.20° rear toe-in acts as a geometric stabilizer, keeping the rear planted under acceleration; front camber of -1.17° gives turn-in bite on wet gravel. 2. Differential:Centre Torque Bias set to 53% sends more torque to the front axle (the slider reads left = Rear, right = Front), killing the power-on oversteer this mid-engine AWD is famous for. Front Viscous is raised to 22 and Rear Viscous dropped to 14 to further bias the car toward stability. 3. Brakes:Kept at stock 2295 N·m / 59% front bias — no need to upset the balance on a low-grip surface. 4. Suspension & Damping:Rear spring (53.87 N/mm) is one notch firmer than stock to plant the rear and resist squat-induced step-out, while a slightly softer rear anti-roll bar (7.00 vs 8.00) keeps the rear wheel compliant on wet gravel. Rear slow bump is set to +2 for compression control. 5. Gearing:Final drive 0.191 (slightly long) smooths wheel torque for more progressive, controllable power on the slippery forest; stock gear ratios kept. 6. Best For:Drivers who struggle with Group B / AWD power-on oversteer and want a planted, predictable RS200 they can actually trust on the throttle. 7. Pro-Tip:If 53% still feels too pushy (understeer), drop to 52%; if the tail steps out, raise toward 55%. Never reduce rear camber to fix push — that makes it worse. Keep Rear Camber at -0.30°.
