I bought some 2" snap hook ratcheting straps from U.S. Cargo Control in Iowa, and have towed my FR-S a couple of times with them now. The snap hooks fit the front eyelets fine, and the materials seem to be substantial. The ratchets work and release without balking. They also offer several colors, and I bought red to match my two red cars (for that trailer steeze/hard towing).

For the back, I bought some Mac's T-bolts. The castings were different on the exact same part numbers, and one didn't fit the tie-down slot on the car without ludicrous force and dexterity. I guess one of the molds used left some excess material on the "spine." Just a touch on the bench grinder made it fit the car fine.
