Vehicle inspection and maintenance for driving on race circuits

Maintenance related information 0

In addition to the regular maintenance tasks carried out as part of the standard maintenance intervals, the following checks must always be carried out before use in the case of high-performance driving on race circuits:

Engine oil

- Check engine-oil level.

After 6,000 miles (10,000 km) of high-performance driving on the race circuit (i.e. a distance of approximately 2.5 x “24h Nürburgring race”):

- Change engine oil and oil filter.

Central wheel lock

Wheels removed - Check that driving pins are installed securely. - Check wheel mountings for damage. - Check that the central bolt and locking mechanism move smoothly. - Re-grease central lock.

After 6,000 miles (10,000 km) of high-performance driving on the race circuit (i.e. a distance of approximately 2.5 x “24h Nürburgring race”):

- Replace all central bolts. - Replace wheel hubs and wheel bearings on rear axle.

After 12,000 miles (20,000 km) of high-performance driving on the race circuit: - Replace wheel hubs and wheel bearings on front axle.

Checking threaded connections for chassis setup

Front axle: - Toe-in on tie rod. - Camber adjustment via spring-strut supporting mount on body.

Rear axle: - Toe-in on tie rod using eccentric screw. - Eccentric screw for camber adjustment.

Front and rear axle: - Camber adjustment within wishbone. - Height adjustment on spring strut. - Connecting link on anti-roll bar.

Wheel guidance joints

- Check joints for play and wear and replace if necessary.

- Check vehicle height and align the suspension and make adjustments if necessary.

Brakes

- Check wear/condition of pads and discs and replace them if necessary. - Steel brake disc: Clean perforation holes if necessary. - PCCB brake disc: Check wear dimension using electronic measuring device. - Check dust boots on brake calipers for damage. - Check brake lines and hoses for damage. - Check brake fluid (boiling point, fill level). - Check brake-disc air guides on both axles for correct seating and damage.

Tires

- Check tires for damage. - Tire pressure: Take race circuit driving into consideration (tires that have been driven until they are warm).

Drive shafts

- Check boots on drive shafts for damage.

Aerodynamic components

- Check aerodynamic components for secure seating and damage. Maintenance related information 0
