I've got a Glasgow programme from 1953 in which this is mentioned. Apparently, there was concern that crowds were drifting away because of the frequency of huge home wins, so the intention was to handicap the HOME team with steel plates, so they got wheel-spin out of the starts! I don't know if it was adopted to any great extent, but I think it was trialled in the programme I've got. I would have to check to be sure.
