John Smith Motorsport - enhanced. John Smith raced Toyotas in the early 90s and basically offered out of Fergusons Toyota in Hurstville some pre packaged modifications for ST185 GT4s. He had a red ST185 with the ATA intercooler, that featured during the time in the local Wheels or Car Australia magazine. Some of the mods included lower diff ratio, blueprinted hi flowed turbo, porting and polishing, lowered springs, different 15" wheels. Not sure there were many other mods available at the time.
