Hi avenan,
you're right, i've forgotten the formula, which is 1/20, also the offroad buggy. The material of the 1/32 is the same as the 1/24 or the 1/20 formula, but it's not black painted.
The philosphy of Wilfried is to build a car that's fast out of the box, so that no tuning parts are necessary. Therefore WWS did not offer any tuning parts.
Normally tuning parts will lead to a higher weight. His cars are designed to win races, not to win beauty contests.
The car is available now for about 100 Euro, ball bearings, ball diff and Revell body included.
Here are two pics from the car including IWaver electronics:
