Considering a set of rims.

Rear fitment isn't a problem, as I'm cutting down a diff to suit. Fronts are 7" wide and +25 offset, has anyone fitted similar width/offset rims to the front of a 120Y?

should fit pretty easy,wat struts and ball joints u got?

I'm confident it won't scrub badly on the outside, I'm mostly worried about clearance to the strut and inner guard.

I'm still running 120Y struts & have no plan/desire to upgrade.

i had 7' 0 on late model struts,and would of had about 25mm clearence from inside of wheel to strut.on a coupe but also not a fordoor.

wont fit on stock struts, will hit the strut tube or spring perch

You can use the below website to see the difference between different width and offset rims, gives clearance between strut and rim plus extra width.

EDIT: says the below when comparing 7" +25 to std b210 4.5" +30 steel rims.

The clearance from stut housing to the inside of the wheel will be 27mm LESS
The outside edge of the wheel will EXTEND an extra 37mm

Leigh I have wheels in the garage with those exact specs. Just pop over and try them on the weekend.
