Back in another life when I used to race , we always used to tie down the left front and right rear with straps over the tires and also used wheel chocks ( could also be right front and left rear ) . The theory was that it allowed the suspension to work and not take a "set" as it would if the car was tied down by the axles/frame or whatever . Don`t know how true that is , but some very serious racers in NC told me that . Also used a hydraulic lock valve in the rear brake circuit so the rear brakes could be locked for towing ( race car had no E brake ) . This was very secure as I was hit from behind when towing , the tow hitch on the trailer was broken loose from the tow vehicle ... the trailer was completely sideways before I got stopped and the car was still in place .... but I did ruin the upholstery on the seat !
You never want to leave a car in gear towing as the vibrations do strange things to the tranny and the ring gear and pinion .
