how big is safe with wheel spacers...

i am working on the suspension on my 31 studebaker and have been struggling finding small backspaced custom wheels. i was looking for 20-22" wheels with a very small backspacing to fit the wheels on the outside of my body. i found some neat offroading wheels which i will go with unless wheel spacers will work. would anyone dissuade me from choosing 2" wheel spacers on my rod, and if so, what is a max safe size, or what could i do to safely use 2" spacers? keep in mind i will be using a very powerful motor with a lot of torque. (i heard if you torque your wheels down frequently you won't have a problem, but the last think i want to happen is my wheel to fall off at 60mph and ruin all of my work)

I stay away form spacers unless longer, stronger wheel studs are used and I never go more than a half inch even then. To many places that will build correct fit wheel these days. 2" wheel spacers seems kinda much , to me would put a unsafe load on the studs.

2" spacers???? You'd have to replace all the lug bolts also. Even if you were running a sixbanger in your truck, that would be really unsafe. As a rule, you really don't want to go bigger than 1/4" spacers on wheels. It's really unsafe on cornering, etc. with anything bigger. The ideal setup is no spacers at all. You may have to check into a custom made wheel or some places can even cut your rims and change the offset for you.

Use the adapitor that bolts to the spindle hub with existing studs. The wheel bolts to a new set of studs mounted in the adapitor. How much Hp don't know but the off roaders use them all the time with the big rims and wheels.

No need to install longer wheel studs with that setup. TF

If you buy the wheel spacers check with the manufacturer as to what the load ratings are. And what they recomend. If your running a Lotus 7 weighing in at 1800 lb. w/300 hp then OK. If you have a 6000lb lead sled 600 hp and 200hp juice shot then I would have my doubts. Talk to the people who make the spacers they may have a better solution to your problem. TF

I have a friend that is using 2" "adapters" on his Pinto auto X
car, he's got 15" Mustang phone dials and 205/50s, all tucked
into the wheel openings. I think he's using these ones...

You could get wheels custom made.

I've been trying to go with a style such as:
http://www.wheelsforless.com/search_...ct_ID=AR309029

but I cannot seem to find any company who makes custom backspaced wheels such as these. It's almost impossible to find black custom backspaced wheels, and even large new age, high tech wheels such as these american racing wheels. The only custom wheels I can find are either rock crawler wheels or vintage wheels. Id really like to go with something like these american racing wheels. Any ideas?

So far you have said small backspace. What is small backspace? Dia. 20-22 inch, OK how wide a rim? Is it a four bolt patern or a five bolt patern? The more information you give everyone the more help there will be. Someone somewhere has to have done what you want, just finding them is the problem. Good Luck TF

Just say NO ...

Wheel spacers and adapters are, as a general rule, not very safe ... IHMO. They change the load on the bearings and suspension. Track width extended way past the pivot point's also can lead to poor handing.

Longer wheel studs, extra lug nuts or lugs only increase the chance of a loose lug nut or a stripped thread on a stud.

Actually, if you're trying to use a 6+" backspaced wheel (Bullitt) on a vehicle that used
a 4" backspace, adding the 2" keeps the load on the bearing the same...

im talking 17-20" rims, around 7-8" wide with a backspacing around 2". anyone ever do something like this with wheels similar to the ones i posted above?

i knew the spacer idea was bad, just thought id ask cause i was told differently from a custom wheel maker who told me better to be spaced than such a small backspacing.

I'm no expert nor do I claim to be one. But you've started the ball rolling by asking whats best or what works. You said you have talked to one wheel maker, start talking to more wheel makers they all have tech. hotlines for help.

Months ago I asked on another web site about air suspension, basicly what I was told if I went air ride the ground would open up and my car would never be seen again(not this site)!! After checking with different mfgs. I went with it. I do not see any problems in my future or hole in the ground.

Keep asking questions, take notes, after a while you can sort the good from the bad. Good Luck TF
