All Inclusive under 100EUR, almost only original parts. A complete guide for a really good working RWD drifter. I claim, there is no better introduction to the topic.
(Almost) only parts from the car are used.
Exceptions: Gyro, tires, servo (The original servo is really useless).

Left:
Gyro - AGFrc GY04m V3.5 -:

The version V3.0 has no AVCS mode yet and this is really a relief.
Gyro - HGV4 - A bit more expensive, but should be top:

Servo - For three EUR a real improvement:
