How to fit big wheels on your b-body: 18" to staggered 22's and more!

This will be the new sticky for plus sizing. Its gonna take a while to rebuild, and any contributions are welcome.
CALLING ALL BIG WHEEL OWNERS!

NEW RULES

Lets keep it clean and concise. THIS IS NOT INTENDED TO BE A PIC THREAD. If you've got anything bigger than stock 17"s, Post ONE or Two good pix of your setup and all available specs: Size of wheel, Offset or backspacing, Tire size, suspension mods, what you had to do to make them fit, and who's car you stole them from.

I'll post pics and info for anyone's car I can find.

Gentlemen, we can rebuild her. I'll go first:

This was the most radical setup I ever ran. 20x9's on the front, 22x9.5's on the rear. The wheels had a +18 offset, so I used 1/4 spacers front and rear to get them just right. On the front, this gave good turning radius, on the rear, I had about 1/2 inch clearance on both sides. It rubbed my dual exhaust, but a hammer fixed that. Tires were 255/35r20's front and 265/35R22's rear.

Great idea firewood. I will throw in my 2 cents.

Having gone from 20x8.5, 20x10 to 22x9, 22x11 I can say with moderate certainity that you are going to rub at some point, especially if you are running sprint springs all around. Maybe I just have bad luck, but I have done a decent amount of work to eliminate most of the rubbing, but times during heavy loads, bouncy roads, or large dips, I still rub a little bit. I have rolled the rear fenders (not visibly noticable), and taking off the trim on the front wheelwells.

With that said, lets talk about the fun stuff! Don't listen to the haters, a well designed and properly fitted 11" wide wheel will fit without any notching.

I am running 22x11 with 15mm OS in the rear and the fronts are a 9" at 20 mm. Toyo proxes 4 265/30/22 and 305/25/22 in the rear.

Without further ado, here is my car. I know I am missing great amount of details, so just go ahead and ask in this thread if you can think of them and I will try to help. However, Firewood knows a great more than I do! (No he doesn't!- Firewood)

Pretty simple setup. 22X9.5's in the rear with 20X8.5's up front. 295/30/ZR22 rear tires and 245/40/ZR20 fronts. The car is lowered 2.5" in the back and 2" in the front. No rubbing and no problems. Nothing fancy

22x9.5 +13 Offset 255/30/22 Tires

24x10 +10 Offset 275/25/24 Tires

Sprint Springs with 1/2 coil cut on the front springs.





To minimize rubbing up front I cut the mounting section off the front fender molding (section where it screws into the fenders) off along the upper arch of the wheel well. I also removed the front bumpstops and added energy suspension flat bumpstops. Will be swapping out the monroes for belltech drop shocks soon cause the monroes are terrible with the car lowered this much.

Update on the above car:

That's an older pic with ST springs in the front cut this is with the sprints in the front cut.




Ive gotten it a little lower in the front even since that picture. Next project is to cut my inner fenders to I can turn without shaving a thin layer of rubber off my front tires each time.

255/30/22
22x9.5
+15 offset.
No suspension mods
Stock height
Fit with the skirts no problem, I cut them because I wanted to.








Update.

1.75" spacer in the rear brings the backspacing to about 4.05" on a 9.5" rim.





RIght at the razors edge of the fender flares. If I had tires from the front it would hit on the flares.

I cant run a tire any bigger then a 255 it appears.

Yeah, its held on with gum, staples and tape, only because I ran out of 5 50 cord.
