Heres a fun one i found.
If you take the traction control off, you still have a very hard time trying to slide the car. so to over come this i found this trick.

1) Remove the rear seat, simply lift it up.
2) there will be 2 connector cables on connected to X drive, LEFT seat. If you remove the two cables and start up the car, ABS, Stability and 4x4 will be turned off.

Once you start driving you will hear a difference in the engine noise, sounds more aggressive. From standstill you can easily do a burn out (4.4L version). when you accelerate in a turn your back end will slide out.
On dirt i did 360s and you can see that most if not all of the power goes directly to the back wheels.
so what essentially happens is that you turn off X-Drive.
it feels like an entirely new car in my opinion, must more rear power.

I've done this on multiple occasions and i've had no issues with it. the car has 250,000 km on it.

Let me know what you guys think! If you have any questions I can prove you guys with photos or anything else


I also ordered an AUX cable for the e53 off of ebay (~$20). Im plan on doing the installation once it arrives. If anyone is curious as to how to do it let me know and I will post some instructions.
