0000... When driving on a race track
WARNING: This page is about a different car, the 2022 BMW X1 and 2021 BMW X1. However, it is still accessible from the selected car via links, so may be relevant.
Attention!
The customer must be informed that, in particular, the brake pads, wear indicator and the flat tire monitor installed as standard are not designed for race track operation. The vehicle is also not designed for motor sport competition racing.
Excessive loading of the vehicle, e.g. by operating it on a race track or in motor sport competition racing, is not covered by the warranty.
If the customer still wants to drive on a race track, the following aspects must be considered/checked, at least:
The vehicle, or rather the engine, must be carefully broken-in before operating it on the race track. A break in period of at least 2000 km.
Recommendation: Carry out an oil change after the break-in period.
The duration of the highly-dynamic trips on the race track must be increased slowly, since the rear axle differential must still be run-in in high-load operation. All the while, the temperature increases.
For driving on a race track, the following extensions must be considered and implemented on the vehicle.

| Scope of checks before driving on the race track: | ||
| Vehicle check | OK. | Comment |
| Perform a comprehensive vehicle check service. -> SCOPE OF THE VEHICLE CHECK SERVICE |
||
| Engine | OK. | Comment |
| Recommendation: Carry out an engine oil change. For the high demands placed on the racetrack and to ensure the full power development, the use of the BMW M Twin Power Turbo engine oil LL-12 FE 0W-30 is recommended if technically suitable for the engine. => See technically suitable engine oils for BMW Group engines Refer to: ENGINE - OPERATING FLUIDS |
||
| Transfer box (concerns only those vehicles with rear axle differential with HOC) | OK. | Comment |
| Perform transfer box oil change. | ||
| Cooling System | OK. | Comment |
| Visual inspection of the radiator for contamination. -> Draw off contamination. |
||
| Brake system | OK. | Comment |
| Check the age of the brake fluid - see Service Manual/Service history. -> The age of the brake fluid should not exceed 1 year. |
||
| Check fill level in brake fluid expansion tank. -> If necessary, top up to the maximum level. |
||
| Check the brake pad thickness on the front axle. -> Wear material thickness ≥ 9 mm -> Ideally, install new brake pads. Recommendation for M-vehicles: Use Sport brake pads, if available for that model. |
||
| Check the brake pad thickness on the rear axle. -> Wear material thickness ≥ rear axle ≥ 8 mm -> Ideally, install new brake pads. Recommendation for M-vehicles: Use Sport brake pads, if available for that model. |
||
| Check the brake disc thickness on the front axle. -> Minimum brake disc thickness: ≥ Minimum brake disc thickness + 1 mm -> Ideally, install new brake discs. |
||
| Check the brake disc thickness on the rear axle. -> Minimum brake disc thickness: ≥ Minimum brake disc thickness + 1 mm -> Ideally, install new brake discs. |
||
| Visual inspection of the brake line and brake hose for tightness, damage and porosity. | ||
| Wheels/tires | OK. | Comment |
| Check wheels/tires for suitability for operation on the race track -> Winter tires, all-season tires and tires on steel rims are absolutely unsuitable. Recommendation: Use Sport tires. |
||
| Check the tire pressure of all the tires and adjust, if required. -> In order to increase the service life and tire performance, a reduction in the tire pressure is recommended for the race track. To do this, proceed as follows:
NOTE:
The display of tire inflation pressure is possible only up to an operating temperature of systems of 120 °C. At higher temperatures, which can be reached during racing operation, the display is suppressed and a Check Control message is issued. After cooling down, the system functions again without limitations. Background: The tire pressure increases due to the temperature increase in the tire when operated on the race track. This reduces the contact surface of the tire to the road, leading to an increased temperature load on the running surface. The adjustment of the tire pressure in tires that have been warmed up as opposed to tires in a cold state leads to a reduction in the pressure and thus, due to an increased tire contact area, to a more equal load on the tire. |
||
| Extensions when driving on a race track: | ||
| Warm up | OK. | Comment |
| Drive a warming up lap. >Bring the engine up to operating temperature. Fast driving at a medium RPM level and medium dynamics. |
||
| Cool down | OK. | Comment |
| Drive a cooling down lap. -> Fast driving at a medium RPM level and medium dynamics. Avoid brake load as far as possible. |
| Scope of checks after driving on the race track: | ||
| Engine | OK. | Comment |
| Perform an oil-level check according to the operating instructions. -> If necessary, top up to the maximum oil level. |
||
| Front axle transmission (applies only to G15 with N63 engine) | OK. | Comment |
| Perform an oil change on the front axle transmission. | ||
| Transfer box (concerns only M vehicles) | OK. | Comment |
| Perform transfer box oil change. | ||
| Rear axle differential | OK. | Comment |
| If a rear axle differential with lock is installed. -> Perform oil change. |
||
| Cooling System | OK. | Comment |
| Visual inspection of the radiator for contamination. -> Draw off contamination. |
||
| Brake system | OK. | Comment |
| Check fill level in brake fluid expansion tank. -> If necessary, top up to the maximum level. |
||
| Check the brake pad thickness on the front axle. -> Replace brake pads when the remaining brake pad thickness is undershot (min. thickness 3.7 mm) |
||
| Check the dust boots on the brake calipers of the front axle for damage. | ||
| Check the brake pad thickness on the rear axle. -> Replace brake pads when the remaining brake pad thickness is undershot (min. thickness 3.7 mm) |
||
| Check the dust boots on the brake calipers of the rear axle for damage. | ||
| Check the brake disc thickness and their state on the front axle. -> Replace brake discs when:
|
||
| Check the brake disc thickness and their state on the rear axle. -> Replace brake discs when:
|
||
| Wheels/tires Note to customer: Perform the following points for wheels/tires immediately after the racing track operation and before driving on public streets! | OK. | Comment |
| Check wheels/tires for damage. | ||
| Check wheels/tires for minimum tread depth. | ||
Check the tire pressure of all the tires and adjust, if required.
|
||
