I need some wheel Clearance Help 22x10.5 Front 22x12 Rear. I am hoping someone has the energy to get through this post, as it is extremely long.:err:
Was hoping I could figure it out myself, but suspension clearance was starting to worry me and needed the
members to chime in. I also have a big brake kit to worry about, 6 piston 14.25" rotor front and 4 piston 15.00" rotor rear.
A few members are running on a 2003-2008 FX35/FX45, 22x10 with 35mm offset on 305/35/22 tires. That is like running a 30 mm spacer, compared to stock in terms of offset.
The equivilant for 10.5" and 12" widths are 42mm and 61mm offset, respectively.

This also helps, but doesn't cover all sizes:

22x10.5 with 305/35/22 tire and 42mm offset

22x12 with 305/35/22 tire and 61 mm offset

Option 1: Semi Concave front, Deep Concave rear
Option 2: Semi Concave front, Deep Concave rear (more aggressive)
Known working offsets that I used (similar widths and tire size):
Pierce/Panzer
22x10 +35mm offset, 305/35/22 (30mm farther than OEM)-- just need to roll rear fender, no other issues.
Viet (non-wide body, V1)
22x10 +22mm offset, 305/35/22 (42mm farther than OEM, :sluggish
Viet (wide body, V2)
Front 22x10 -3mm offset, 295/30/22 (68mm farther than OEM:eek.:, 30.12" diameter tire)
Rear 22x12 -10mm offset, 335/25/22 (101mm farther than OEM:eek.:, 28.59" diameter tire)
Humberto (wide body)
Front 22 x 10.5 +11 Offset offset 305/35/22 tires
Rear 22 x 10.5 -5 Offset
Someone is going to ask, so I'm going for Forgestar F14 in Titanium (maybe silver)
Options:
Deep concave
22"
22x10.5 offsets from +10 to +49
22x12 offsets from +29 to +68
Semi concave (to me these are pretty flat)
22"
22x8.5 offsets from +12 to +51
22x9.0 offsets from +18 to +57
22x10 offsets from +31 to 70
My thinking is either go biggest I can, with the 10.5 front and 12 rear so both are deep concave.
Or I can get the staggered look even more by using a semi concave front and deep concave rear. The additional benefit of this too is I can use a smaller wheel and tire setup in the front, so the smallest is 9" to accommodate the 265/40/22 properly is a 9" wheel. The purpose of this is to reduce steering vibrations, shimmy, etc... as the larger the width of the front tire, the more you feel. FX's are notorious for steering wheel shake at the 60-75 mph range, even with a Hunter Roadforce balance and steering bolt tightening.
265/40/22 and 305/35/22 will be fine on the AWD, so close in tire height and Pirelli Scorpion Zero Asimmetrico come in both sizes.
Here is a picture of semi concave front and deep concave rear (note the Camaro is 22x9 and 22x10.5, which is one of my options. The concave difference doesn't really show up there, not sure why? Angle of picture?):

22x10.5 with 305/35/22 tire and 42mm offset

22x12 with 305/35/22 tire and 61 mm offset

Option 1: Semi Concave front, Deep Concave rear
22x9 front +15mm offset on 265/40/22 tire (30.34 inch tire diameter, 38mm more than stock offset)
22x10.5 rear +34mm offset on 305/35/22 tire (30.40 inch tire diameter, 38mm more than stock offset)
I am 100% sure the front fitment works (had it before).
I am 90% sure the rear fitment works, as 10.5" rear with an offset less (more aggressive) than 40mm offset should work (based on what I read online, see here http://www.rimsntires.com/wheelfit.jsp?sized=22&sizew=10.5&pcd=5x114.3&offset=41).
Inner suspension clearance is where my 10% worrying comes from. I can push it out farther to be safe as Viet ran 42mm more than OEM. What's another few mm=)

Option 2: Semi Concave front, Deep Concave rear (more aggressive)
22x9 front +21mm offset on 265/40/22 tire (30.34 inch tire diameter, 32mm more than stock offset)
22x10.5 rear +40mm offset on 305/35/22 tire (30.40 inch tire diameter, 32mm more than stock offset)
I am 100% sure the front fitment works.
I am 80% sure the rear fitment works. This sticks the wheel farther in, so less suspension clearance, but more fender clearance. Website says this works 100%, but I am not convinced... yet. Anyone know how much inner suspension clearance we have for the rears? No strut in the rear, so hopefully it will be fine??? I'd rather have less chance of rubbing the plastic fender and be a little more tucked in vs Option 1.
Option 3: Deep Concave all around22x10.5 rear +40mm offset on 305/35/22 tire (30.40 inch tire diameter, 32mm more than stock offset)

22x10.5 Front AND rear +34mm offset on 305/35/22 tire (30.40 inch tire diameter, 38mm more than stock offset)
I am 80% sure the front fitment works (strut is pretty close, which the front has that I need to worry about).
I am 90% sure the rear fitment works (see Option 1).
Option 4: Deep Concave all around (less aggressive)I am 80% sure the front fitment works (strut is pretty close, which the front has that I need to worry about).
I am 90% sure the rear fitment works (see Option 1).
22x10.5 Front AND rear +40mm offset on 305/35/22 tire (30.40 inch tire diameter, 38mm more than stock offset)
I am 50% sure the front fitment works (pushes even closer to strut).
I am 80% sure the rear fitment works (pushes closer in the fender).
Option 5: Deep Concave all around, maximum width in rearI am 50% sure the front fitment works (pushes even closer to strut).
I am 80% sure the rear fitment works (pushes closer in the fender).
22x10.5 Front +42mm offset on 305/35/22 tire (30.40 inch tire diameter, 30mm more than stock offset)
22x12 Rear +61mm offset on 305/35/22 tire (30.40 inch tire diameter, 30mm more than stock offset)
I am 40% sure the front fitment works (pushes even closer to strut).
I am 20% sure the rear fitment works (pushes closer in the fender).
Option 6: the Aggressive Rookie, Deep Concave all around, maximum width in rear22x12 Rear +61mm offset on 305/35/22 tire (30.40 inch tire diameter, 30mm more than stock offset)
I am 40% sure the front fitment works (pushes even closer to strut).

22x10.5 Front +30mm offset on 305/35/22 tire (30.40 inch tire diameter, 42mm more than stock offset)
22x12 Rear +49mm offset on 305/35/22 tire (30.40 inch tire diameter, 42mm more than stock offset)
I am 90% sure the front fitment works (pushes even closer to strut).
I am 90% sure the rear fitment works (pushes closer in the fender).
I am more confident in this setup because it pushes it so far out, inner clearance for any suspension should be fine. But the 10% is again the fender rub.
