Sierra based Roadster wheels offset ET

[loony]

I'm still trying to figure out if my 6,5x15 ET20 wheels will fit rear arches...
What ET is possible to fit in Saturn/NTS rear arches (195/50R15 tyres) ?

Can you post your wheels ET and measure "free" space between tyre and arch ?

You need to be around et 38. I very much doubt et20's will fit they will stick out too far.
Edit to add my et38's have around 6mm between the tyre and the rear arch lip.

standard ford sierra off sets is what you need (30-41 iirc)
offset would actualy change with rim width making it more tricky to calculate wat you can actualy get away with.

i run 195/50/15 on 6.5jx15 et38 wheels
