So I have a 4'' TC kit and will be adding 2'' pocket style flars and want the wheels to be flush with the flares. on my 07 Classic. Looking for wheel options! Something that will fill the gap good. I have a chance to buy Fuel Octane 20''x9'' rims with 305/55/20 x 12.5'' rubber. Rims are +20 offset and 5.75'' bs. Will this setup work with the 4''? Open the other ideas on what offset or backspacing I should be looking for. I don't fully understand it all..don't want to ruin the set-up first time. Thanks guys.
