wheels

Where might you be buying them from? any reputable custom wheel shop around here should be able to tell you before you buy them whether they will work or not. Call up Jay Wheelz @ XDCinc.com and he will tell you

You get one wheel off, you mesure the clearance in the fender and then when you know how much space you have, you choose the width, offset and tire size you need. That's what i did. So you have +38mm offset

38mm*1 inch/254mm=0.15 inch that means the point where the wheel mount on the break is 0.15 inch toward the outside (if you have a 8 inch wide wheel, 4.15 inch goes inside and 3.85 goes outside) A 90 degrees square is what you need to do mesurements. Do not trust any shop to tell you if they'll tuck, most of the time they don't know how to calculate offset. They will give you a wheel with OEM specs

Correction
38mm*1 inch/25.4mm= 1.5 inch
so the center of the rim is 1.5 inch on the outside like a fwd. It will clear fenders but you might rub inside in the front when you turn
