Gearbox: short ratios anchored on the hairpins
On a touge road you spend most of the time between the slowest corner exit speed and a moderate top speed. The gearbox should therefore be short, with ratios set from the exit speed of the slowest corner you take regularly, so the engine is already in its power band when you get back on the throttle. A long gearbox wastes this by leaving you under-revved out of every hairpin.
Suspension: medium, not stiff
Touge roads are bumpy. A suspension that is too stiff makes the car skip over bumps and lose grip mid-corner. A medium setup, softer than a pure grip build, keeps the tyres on the road, and the slow dampers set the overall balance under steering, braking and throttle. If the car feels unsettled on rough tarmac even when the slow dampers feel right, soften the fast dampers.
Differential: responsive but stable
The differential should help the car turn in without letting the rear step out. Stability comes first: the rear must never let go before the front. Acceleration lock adds only what is needed so the inside wheel does not spin, and coast lock stays gentle so the car does not rotate when you lift off.
Alignment and brakes
Moderate camber and toe keep the tyres working through long chained corners, and brake bias follows the weight distribution and the load transfer under hard braking. These values depend on the car and its drivetrain, which is why a fixed table does not work.
Practical tips
-
01
Set the gearbox first, then the suspension, then the differential: each step changes what the next one needs.
-
02
Test on the same corner several times before changing a second setting.
-
03
If the rear steps out on exit, reduce the acceleration lock before touching the springs.
FAQ
Should a touge car be stiff or soft?
Medium. Softer than a grip or track build so the tyres stay on bumpy roads, but not so soft that the body rolls through chained corners.
Which gearbox suits touge?
A short, tightly spaced one, with the ratios set from the exit speed of the slowest corner. It keeps the engine in its power band after every hairpin.
