It’s a good idea, in general, to bend as little of the lip as you can get away with. The EcoNova’s wheelwells are quite long and much of the arch doesn’t even interfere with the tire, so we really only have to pay attention to the top portion. Along the same lines, only roll the lip as much as you need to clear the tire during travel and deflection. If you don’t have to roll the lip flush to the body, don’t. That just increases the odds that you’ll crack the paint or deform the quarter.
