In the past when dropping my bug all the way down in the front with the adjustable beam the tires will scrub the edges of the finders when I hit bumps in the road. So I’m assuming that if I plan on sticking a wheel that is 1.5” bigger I’m going to have to keep the back spacing the same and put that extra 1.5” on the inside of my wheel!!! No but wait the back spacing wouldn’t be the same. It would change to +45mm back spacing. Somebody check these numbers. And does any body know if you have enough room under there to put 1.5” on the inside of a wheel????
