My U12 is at stock height, stock springs. keeping in mind it has an LPG tank here.
on my old tyres, 215/40/ZR17, not a single problem with bottoming out or cutting tyres.
now ive upgraded to 215/45/R17, and it cuts my tyres so often. Rolled the guard lip thingo on the inside, but it still does it. Its currently about to get lowered on Lows at the back, so ill see how it is then.
