I'd go with a 275/45/20 it will fit a little better and it is darn close to stock.

The 275/45 will fit the 3/6 well/ You can run almost any typical 20" rim and backspacing with this tire and drop. Plus this tire size has a better selection of quality tires that you should like better IMO.

Talk to Carbondogg- he has had the same size tire with 20's and something like a 3/7 drop i think.

Taking off my bumber and spare tire didn't make that Big of a difference. On my 3/6 drop, it was for the better IMO

here's a pic to get an idea right after i dropped

and another with some bling.... Here's A Sir Mikes pan on with that drop to compare w/ Carbon's CC pan
