Z4 on the skidpad

Some of you may have seen the video "how NOT to drift a Z4" I posted before. This is me practicing how to control the so-called tank-slapper:

You 're not giving up, do you Asbjorn? I always enjoy watching your adventures, keep it up mate.

If you don't mind I have a few remarks :

1. You 're fighting the steering wheel too much. You have to reach the point when you turn sharp in, break traction with full throttle, lock the steering wheel in opposition and regulate the angle with the throttle. That means as little as possible corrections and letting the steering wheel turn itself back to you once you 'have finished one side sliding. Again you terminate this one side sliding by letting off the gas pedal completely, this will throw you sliding to the opposite side (in a figure of 8 manner). If you want to eliminate the slapper and this weight transition stay on throttle while you manually slowly straighten the steering wheel in which case keep in mind that you have to stay on throttle even a few meters after your steering wheel is straight.

2. Try to use your left hand too and never cross your hands over. Hold the st. wheel at 9-3, let it go when drifting, catch it again and make corrections from 9-3 to 12-6. If you master the letting it go it's more than enough going from 9-3 to 12-6.

3. Practice figure of 8 using 2 cones 10-12m apart for precision, this is the most important exercise once you mastered the skidpad.

It's not easy, the remarks above took me over a year to work out on dedicated track tools but it's so much fun and forgive me again if I sounded pointy, I'm still learning like you.

Have a look at wheel steering balancing in the video below mostly on 3rd gear 90-100km/h slides. The nervous correction is on 4th gear at 140km/h.

Many many thanks for the remarks and supporting video. Feedback of highest quality right there.

And drifting at 140km/h... holy cow...

Great video. If I could have found an E39 M5 here in China I would have bought one. Probably one of the best cars ever build (had a 523i back in Denmark). Drifting that and the E89 must be like night and day - you probably even have some suspension tweaks on the E39?
One factor has not been addressed yet - the "panic factor". In a controlled environment where risks are at a minimum "anyone" can drift, but drifting or saving an unexpected slide in public takes real skill.

Totally agree, on public streets I personally fear to disengage the traction controls.

The m5 is 100% stock, only electrical/gps, insulation and the rear sits are removed for weight and space savings (it can accommodate 8 16'' wheels, enough for a few passes ) and the electrical and heated front seats replaced with lighter ones from a 520. It's a magnificent car, my previous track car was an e34 s38b38 m5 and the transition to the e39 just makes you a driver on a different league. Had it been 300kg lighter it would surely be competition material.
