That wheel and tire combination should clear the UCAs just fine. Your only potential issue is tire rub on your front valance and possibly your fender flare (if you have an FX4), given that those tires are 34.3" tall. You may need to trim slightly even with the coilovers set at their full ride height. If you do end up cranking the coilovers all the way up, then a 2" block will result in some rear rake. You may want to consider doing a 2.5" or 3" block instead, but that really depends on what look you're going for. You may want to give us a call directly at 1-877-578-2433.
