I just put Black Rhino sprocket 20" x 9.5" with a -15 offset on 275-55-20 tires. They seem to fit but I did have to remove my front mud flaps and I get some rub when I turn once in a while. So I'm thinking I lift this for looks and so I can stop the rubbing and put my mud guard back on. I read alot about the Billstein 51
00 shocks
but not sure about springs. Do I keep the stock springs for front and rear?
