There are a number of options for increasing clearance in a Scamp
: raising the axle
, changing the axle
arm direction in some cases (I don't know antything about that), trimming wheel wells if the clearance issue is just with the edges.
Once you have some space you can put larger wheels/tires on.
I've only had experience with the wheel well trimming. Our Scamp
had a 1.5" lift in it from the factory but others have done 3 or so inches after the fact themselves with the help of a welder.
Some searches might help because there has been quite a bit of discussion about this over time.
