wheel off set?

[Que1]

hello all
i'm sure this one has been answered before, but i couldn't find anything when i did a search so sorry in advance...
i'm looking for some after market wheels for my chimp, does anybody know the correct offset for the front and rear?
I'm also looking at fitting 17" all round.Has anybody done this without the fronts rubbing?

I'm assuming that the running gear of the Chim is the same as a griff, if so i've just done the 17" conversion, with help from Speedline Corse & Pennisula.

Many thanks to Ivor @ speedline for his help



my wheels have a 28mm offset and if i recall 7.5j, for all four, and i'm running 215 40 17's on the front & 225 45 17's on the rear, and my tyre choice is the superb Goodyear F1 gsd3.
