Hi I trying to push to the look and performance on my 85 Elky. I am currently running in 18 x 10 in the rear and an 18 x 8 in the front. I want to run something like a 20x11 rear, 20x9 front. I'm on Viking coilovers full suspension and rear end. It's pushing over 750 horsepower so I'm not worried about the weight of the 20 inch rim. I kind of want to have a road race style and look, although I know they pretty much always run an 18 in that class. I'm willing to do body notching or whatever it takes to fit a wider wheel combination on car to get the look am I after. Does anybody know offsets or have done this? Thanks in advance.
