tie downs

Don't have a race car now, but on my old Dart Super Street car I had a winch pull tab welded on the front of the K-member and two tiedown loops welded on each rear frame rail behind the slicks (back-halved car).
I'd winch the car onto my trailer against the front tire stops, then crosstie the back of the car to opposite sides of the trailer with tiedowns.
Trailer towed great and the car never budged.
Although the trailer was open, I had a large storage box built across the front of the trailer that also acted as a windbreak/streamliner with lights shining back onto the trailer to make it easy to load at night. Also had an electrical pigtail that I'd plug into the front of the car - it operated the race car tail lights the same as the trailer brake/turn signal lights. Never had a problem with other drivers not being able to tell when I was stopping or turning with both the tow truck tail lights, trailer tail lights, and race car tail lights all lighting up in unison.
