it was WAY to hard to driving the streets.. maximum lowering was around 60mm +/- the Vmaxx is able to go lower..
i think if you want to go lower then 7,5cm you will need to install airride insted. the shafts and the lower suspension arms isent build to run with 7,5cm lowering..
so i dont belive it would be a good idea to go any lower.. airride is the way..
