I agree!! The first image which came to mind was the wicked witch in Oz under Dorothy's house. A lousy way to die, or to lose your legs.

I didn't. I prayed a lot.... My linkage came loose on my 6sp. shifter, so I had to do what I had to do!

Wish I had an M5 but this is what I do with my wannabe M5 (E92 M3)...

BEFORE FIRST SESSION

1. Watch instructional YouTube track videos the night before.
2. Visual inspection of what I can and check fluid levels.
3. Remove all loose interior items (junk).
4. Remove wheel hub caps and license plates.
5. Check wheel lug torque.
5. Drop tire pressures 2 psi lower all around below the recommended cold tire pressure.
5. Start and idle motor 5 minutes to warm up before start of session.
6. Set car to display oil level and other monitors.

DURING SESSIONS

1. Warm up first lap at about 70% speed.
2. Cool down laps between hot laps when needed to give motor and brakes a break.
3. Warm down last lap at about 50% speed.
4. Leave motor on for 5 minutes after session to minimize heat soak and open hood for further cooling.
4. Check hot tire pressures. I like to see them at about 5 psi above the recommended tire pressure. I usually end up lowering my fronts an additional 2 psi to get more front grip but I sacrifice in outer tire corner wear. Depending on the track configuration and direction (CCW or CW), I keep my tire pressure 1 psi lower on the side that sees the most demand.

END OF DAY
1. Put all my junk back in car.
2. Mount my radar detector back on.
3. Install hub caps and license plate back on.
4. Adjust tire pressures and check wheel lug torque WHEN COLD.

Hope this helps someone.
