Transport Dept were anal up here. A mate had a Barbados LH SL/R L32 with M20. He put on L34 flares & spoilers and filled the flares with a set of 13 x 7 and 13 x 8 Dragways, as was the done thing back then.
He eventually/inevitably got pulled over by the cops and was given a ticket to visit the pits. He was forced to remove the Dragways and they also wanted him to remove the flairs and the spoilers because his car was an SL/R not an L34.
He argued with the Transport inspectors and eventually got to keep the flairs etc but the wide wheels were gone.
