The idea behind these “Plain Towers”, is to simply be able to adjust the car more precisely. Currently when adjusting the cars, we change toe in, antisquat, arm height, etc, by making changes of 0.5mm-1mm. These are already noticeable changes, and often we feel a 0.25mm change is right. When it comes to roll centre changes made by moving the top link, we have until now been forced to make 2.5mm changes, which is the distance between two holes. This change is too big in our opinion. When the car is almost right, and you just need a bit more of “something”, moving a top link 2.5mm up or down, or 4.5mm in or out, is simply too much. With this system it is possible to move the links just 1mm, up, down, or in or out.
The hole in the black square insert is in the corner, so flipping it around moves the hole 1mm, resulting in 4 positions, the corners of a 1mm square.
The inner row, lowest hole is the equivalent to the middle lowest hole on the stock shock tower.
