Lately, I had been testing a few configuration mods to run the stock cars faster than 700km/h. So far, with the choice of wheels provided by these modes and the game itself, I could only reach 640km/h on a Hirochi Sunburst before exploding all wheels. Any modder here who can design high-speed steel wheels used on vehicles which are designed to break land speed records in real life? I have provided some screenshots of the 600km/h+ Sunburst.
