Just put on 18" alloys straight off a mk2 RX300 onto my mk1 RX300, went on a treat, I used 235/55/18 tyres, get a little rub on full lock but nothing to worry about. Looks much better in my opinion too.
exactly the same as me but just need the info as a friend does my tracking and he has no info on the settings later wheels do look great on mk 1
