Single seater Max track/ Max width

[jonnboy]

Hi, could anyone clarify if there is a max track for single seaters. I note the before and after wheel widths but cannot find a statement on the track itself. I am designing for around total width of 60" which seems to be common, but want to know if there were specific limits

thanks

Yes but as none of those specify a track width the max width of N/A still applies
