17x8 @ +35
-will be approx 10-12mm outside your front guard @ 0 degrees camber. (depends on tyres)
-In the rear, it shoul dfit fine, there is that much camber adjustment if it were a problem you could just chnage your camber...and you will only need to if it is really low.
I ran 17X9 @+39in the rear and had it really really low and i made it fit.
I think i was wrong then with saying you can run up to 6.3 inches of backspace
Ive just done some calculations on my old setup and i came up with;
I fit 17x9@+39 in the rear, this required about 5 mm control arm trimming.
So id say to be safe, a 9 inch rim in the rear really want a +30 offset.

You need at least 5.5" backspace to clear the trailing arms in the rear, and the struts in the front.
for example a 9" wide rim would need +25 offset or lower to give you the right backspacing.
Decide what width wheels you want to run, workout what offset will give you 5.5" of backspacing, then roll/pull/bash the guards until they fit.
To workout the backspace for a 9@+30, itd be...
9/2=4.5 inches, thats the centre of the rim,
Hence the flange is now 30 mm further toward the outer so we'd see 4.5 inches + 30mm.
Thats 114.3mm (4.5 x25.4mm) + 30mm=144.3mm, or 5.7 inches
This is the max in the rear...5.7 inches..
The front is a little more generous...but not by much,around 5.7-5.8 inches willhave the rim and tyre flush with the guard (0 camber), and near no clearance left on the inside toward the stock shock.
Those figures (5.7 Inches in the rear) are pushing it.
I agree with you at around 5.5 inches to be safe, though if the cars low, it wont fit the stock guards
But it does work @ 5.7 in the rear, as i said i ran 9@+39 in the rear with a minor control arm trim and thats around 6 inches of backspace
Having said all this, you need a neat tyre as well, with 6 inches of backspace, i had a stretched tyre to fit it, wouldnt have worked without it.
