Wheels Wheels Wheels
Below is what I played with to help decide on wheels and tires
Stock 18" Wheel Specs Width 8 inches Offset +45 mm
New Front 20" Wheel Specs Width 9.5 inches Offset +30 mm
Inner Clearance: 4mm = 0.16 in LESS (the inside of the wheel to the strut housing)
Outer Position: EXTEND an extra 34mm = 1.34 in (position of the outside edge of the wheel)
New Rear 20" Wheel Specs Width 10.5 inches Offset +29 mm
Inner Clearance: 16m = 0.63 in LESS (the inside of the wheel to the strut housing)
Outer Position: EXTEND an extra 48mm = 1.89 in (position of the outside edge of the wheel)
Stock Tires- 245/40R18
Section Width: 9.64 in 245 mm
Rim Diameter: 18 in
Rim Width Range: 8 - 9.5 in
Overall Diameter: 25.71 in
Sidewall Height: 3.85 in
Tire - 245/30R20
Section Width: 9.64 in 245 mm
Rim Diameter: 20 in
Rim Width Range: 8 - 9.5 in
Overall Diameter: 25.78 in
Sidewall Height: 2.89 in

Tire - 255/30R20
Section Width: 10.03 in 255 mm
Rim Diameter: 20 in
Rim Width Range: 8.5 - 9.5 in
Overall Diameter: 26.02 in
Sidewall Height: 3.01 in
Diameter Difference: 1.2%
Tire - 285/30R20
Section Width: 11.22 in 285 mm
Rim Diameter: 20 in
Rm Width Range: 10 - 11 in
Overall Diameter: 26.73 in
Sidewall Height: 3.36 in
Diameter Difference: 3.82%
Tire - 305/25R20
Section Width: 12.00 in 305 mm
Rim Diameter: 20 in
Rim Width Range: 10.5 - 12 in
Overall Diameter: 26.00 in
Sidewall Height: 3.00 in

I know most run a 245/30/20 and a 285/30/20 on our cars in 20", But I think the best setup for me to try is what I have in bold above. The sidewalls will be 3" thick they are both 26" tall only slightly taller than stock. So as long as the 9.5" rim doesn't cause me any issues and the 305/25/20 doesn't rub on the inside or outside from its width I think I will be happy.
I can't wait to get the wheels and order tires and start test fitting I will get some pictures up for sure. Let me know what you guys think. I just can't wait until it's done and they are on the car so I can focus on something else

Members choose the out of stock spec for the ride comfort.
Since the overall diameter for that setup is about 1" more than stock wheels, BBK is usually recommended.
Some do keep stock specs by choosing 245/30/20 in the front and 285/25/20 in the rear, but these ride like craps due to the much thinner sidewalls.
255/30R20 and 305/25R20 are fine, but I suggest you check their price tags first.
BTW Johnnyreno, from other posts, can I gather you are one bruddah from the islands? If so, where?
