^ assuming you have some type of truck (or you can rent), I used to get a u-haul car trailer for the weekend and load my gutted track only M3 on that bad boy and drive from Delray Beach to Sebring. Worked great. Never a problem. Just need some wood for the front not to scrape. Cost very affordable.

 

Other option is you can run P Zero Corsa, they come in OEM 20" sizes actually. But they are $$$$.

I considered doing this for a while, but they have a lot of mixed reviews, but come standard on a lot of very fast cars.
