    how high are speedbumps?

    about to order some 40mm lowering springs my splitters sitting about 145mm off the ground on the standard springs so im looking at 105mm clearance? will that be enough?

    its dependant on the angle of the incline/drop... if its smooth it wont scrape, shaper it is the worse itll be

    Mines on 40mm atm, although looks more like 55-60mm and it's hell around here! Always hitting my centre section and back box . It's certainly worth it though

    Between 75 and 125mm height, with a 1:12 - 1:15 gradient over the length of the ramp (which are usually between 1.125m and 2m)
