I bought my sport about 4 years ago as a work in progress and the previous owner did the wheel swap, His name was Cliff Fisher and he is from Texas. He had the adapters and caliper mounts custom machined. He went through a few mock ups till he got it to work well. I have put quite a few miles on it, so it seems to work well. Getting the rear wheel off takes some time though. There is almost no clearance between the drive shaft and the tire.
