perfect thanks!

I know the centre bore of the vantage is 68.1 and the mustang is 70.5 so yeah a 2.4mm difference so 1.2mm thick ring needed I am thinking.

Will see what I can find online

 

The Titan 7 wheels is also supposed Mustang fitment. Seems like it's compatible with Gaydon Era AMs.

 

Thanks, next problem is a tyre for a 20x10 front!

 

I think probably 255/30/20 or 265/30/20 front with 20x10 ET40 and 295/30/20 or 305/30/20 with 20x11 ET50 rear.

 

Think 255 will be too much stretch as 255/35/20 is a nice tyre to get.

255/30 and 265/30 do not come in the Aston load rating so cannot be used.

265/35 would be needed but +3.4% rolling radius to current setup.

Feels like the Titan7 wheels wont work.
