Need some help figuring out offset for rims...

Ok everyone, I'm looking to get a set of aftermarket 18" or 19" rims for my 8. They are staggered so I'm going to need some tire/rime guru person to help me see if the offset for these rims will fit.

The first set is 18x8 (fronts) 18x9 (rear) - both have an offset of 38mm

The other set is 19x8.5 (fronts) 19x9.5 (rear) - fronts have a 20mm offset and the rears have a 30mm offset.

Which set will fit the 8 without rubbing anything? I dont mind putting wheel spacers and long studs in to make them clear the calipers or anything like that.

Thanks !!

im no guru but I know what works and what doesn't

the 18" combo would probably work with no problem

the 19" combo's offsets are wayyyy to low for the 8, ive seen a few guys run a +22 front wheel but even that is a really tight fit, i don't think the rear will even be possible to fit.

the rims make a bit of a difference on fitment but alot has to do with the tire choice

Your first choice,,,

FRONT 18x8 38mm offset

Current Wheel Specs: Width 8 inches Offset 50mm

New Wheel Specs: Width 8 inches Offset 38mm

inner position: 12mm MORE
(the inside of the wheel to the strut housing)

Outer Position: EXTEND an extra 12mm
(position of the outside edge of the wheel)

_______________________________________________-

REAR 18x9 offset 38mm
Current Wheel Specs: Width 8inches Offset 50mm

New Wheel Specs: Width 8inches Offset 38mm

Inner Clearance: 1mm LESS
(the inside of the wheel to the strut housing)

Outer Position: EXTEND an extra 25mm
(position of the outside edge of the wheel)
--------------------------------------------------------------
Your second choice ,,,,,,,

Front,,, 19x8.5 offset 20mm

Current Wheel Specs: Width 8 inches Offset 50 mm

New Wheel Specs: Width 9.5 inches Offset 38 mm

Inner Clearance: 24mm MORE
(the inside of the wheel to the strut housing)

Outer Position: EXTEND an extra 36mm
(position of the outside edge of the wheel)
-------------------------------------------------------------------

Rear,, 19x9.5 offset 30

Current Wheel Specs: Width 8 inches Offset 50 mm

New Wheel Specs: Width 9.5 inches Offset 30mm

Inner Clearance: 1mm MORE
(the inside of the wheel to the strut housing)
