that's the top numbers your refering to
- 500 (used to be 5x): depending on engine capacity, car weight and width which I don't know exactly but don't really care. As an example: most small sedans/hatches, coupes like integra, silvia, celica, roadster MR2/S, roadsters etc...early skylines, chasers, evos, sti, rx-7 I believe are in this class too.
- 300 (used to be 3x): same as above but larger, heavier class...NSX, Supra, GTO, GT-R, RX-7, Evo, Z32/33, RX-8, Chasers, Skylines, Stageas etc
- Yellow plates: kei plates... I don't take note of the numbers.
- 400: lorries, special vehicles
- 800 (used tobe 88): marked police cars and emergency services ambos, fire brigade
