I have a 2008 Lincoln Mark LT I bought some used 325/60/20 Goodyear duratracs to put on the stock wheels I had originally planned on running it with a 2.5" level buy was told they'd rub on the UCA so would 2" spacers make it work I have no problem trimming also how bad would this set up be on my front end

 

You are more than likely to rub without spacers Those tires are almost 36 inches tall and 13 inches wide. Cant say if you will still rub the UCA's with 2 inch spacers but I rub in reverse with 33x12.5 toyo open countrys r/t on the lower valence just a tad with aftermarket wheels with a 2.5 level
