Welcome Paul,
As the axles are still In the same place as they are in the mini subframe, are they not the same as they would be for the mini
My Cox last weigh in was 620kg it’s lost abit since then, but still over 600kg’s.
I don’t have a Cox brochure in front of me but from memory it states something like 10,hundred weight which is equating out at 509kg
seems ambitious ?
But still this equates to a weight comparable to a 60’s mini.
