We put 300 miles on em today , half of it on the blue ridge parkway and she never dragged anything. But I rode it before it was lowered and it scraped a few times. Its all in the way you ride but I would say if youre not too aggressive and you don't have too much weight on it then 11/2 in the rear and 1/2 front works pretty good.
