That's the trick... no height gain at all... it's just forcing the lowest point of the car to no longer be there in speed bump situations...
SCIENCE: Think of it like a 20p piece... they are designed to role perfectly like a circle so they work in vending machines etc... so the total diameter of the 20p piece at any point is always the same... even though the sides are cut out like a hexagon... it's not a circle but has the same functionality as a circle... same principle... the upward curve keeps the car low and tidy... yet can go over speed bumps provided you angle the car in such a way that the bump slots into that extra space you create by the upwards curve.
A lot of us on here had initial shock reactions of horror when brad started this project, many thinking it would never see the light of day or would fall to bits under the weight of filler, but as most on here now recognise that the car is like brad always said it was a showcar and he wanted to go wild and wide with free license and free thinking. despite many setbacks and lack of support he has showed amazing tenacity, and stickability where many many others would have given up. brad has done everything he said he would do, and documented every step, providing hours of forum debate , humour and difference of opnion.most on here regardless of whether they love ,hate or have any views on the end product would agree that brad has a lot of qualities , staying positive against all odds and the doomsayers,and taken a hell of a lot of flak in good spirit, carried on regardless to bring his vision to life.bloody good on him ! i for one think it has turned out way better than i ever thought, anyone can go and buy a veilside bodykit or similar, brad and co have done it all themselves and i absolutely take my hat off to him !
