I have a 1950 3100 with the stock original suspension and 16" rims. I have read allot about the 3" and 4" drop. I would like to do the 4" drop but concerned that if anything would go bad the 4" and the scrub line would be to low. I really would like to do chrome smoothie 15" rims and fatten the rim up a bit, but not against 16" to keep it somewhat off the ground if i had a flat. What rims and tires are you running with both the 3" and 4" drops from sids? I am not looking to change my springs at this point. Please chime in with info and pictures would be awesome. Thanks Steve
