Tighten Porsche centrelocks to 440lbs, who depresses the brake if you are on your own?
By using your handy ratchet spreader/clamp that you will have to hand, along with all the other kit...? You just place a short plank of wood across the front of the drivers seat with a towel behind the plank to protect the beautifully stitched seat leather and place the other end of the spreader against the brake pedal, and ratchet it up good and tight.... Simples..?????
