How odd should you mention rim widths etc, as thats also all gone out of the window lol also strange how you mentioned sponsership.
I've just bought a full Rally-Cross wide arch kit, consisting of wide front wings, wide skirts, and wide rear quarters which I shall be fitting. This is all secondhand, but new, never fitted.
I've done a sponsership deal with a fibreglass panel company who I'm going to get the bonnet and tailgate from.
So now I'll be running 8 x 15 rears at ET20 to widen the track out to the new rear quarters.
At the front I will be running 15mm hubcentric wheel spacers with 8 x 15 ET40 wheels also to widen the track.
All this said means I can lower the COG quite dramatically.
Spare wheel well is coming out in favour of an alloy sheet.
Thanks for the gen on the wheels Al, I'll certainly have a look at Rota's as opposed to OZ Ultra (or) Super Leggeras...
