Ok, the reasoning behind the 3mm tower is that the mounts of the gearbox tops are not that great. Looking at these they are going to be a weak point, therefore i have chosen the 3mm, this will not stop the mounts from breaking but i do think it will lessen the force on these mounts.
The same sort of problems have also occurred on other cars, such as the d4. The shocktower mounts are the same type of design and this car also runs 3mm towers, the towers very rarely broke when i run it along with the gearbox tops.
Having 4mm towers would only add more pressure onto the gearbox tops due to being less flexibilty during impact.
Being made from 4mm would also push the price up alot, would people really want to be paying £18-£20 for a shocktower? Im not looking at making the car invincible just a little stronger, but dont get me wrong. Things will always break, whatever the thickness whatever the material if hit hard enough or caught on the right angle.
