Hi all,
just working with my son on our escort mk6 3door show car project and I am swapping the rear drums over to the 285mm ST170 disc calipers carriers etc
trying to find out the difference in track width from the old posts but can’t get a definitive answer!!!

really need to know as we’ve just managed to get some bola b10’s in 8x18 that fill the arches nicely
so as long as it’s not too much I can add some camber (already rolled the arches) and get them just tucked under the arches. Tyres are slightly stretched 205/40/18’s and dropping it on lowered springs 60mm
TIA
