OK quick update. I got the wheels to fit. I used my dremel and took off about 2mm off of the inside part of the wheel. The whole hex still fits in, I just shortened the inside walls. This does not affect the depth at all, just took some plastic that goes around the hex. I wont have to use washers anymore.
Since I had the dremel at work already I decided to start on the shock tower. With the dremel I took off about 2mm of plastic so the 52mm motor would fit.
