offset shafts ??
offset upper a-arms question ?
Does anyone know what the offset is that is built into the
shaft on the "VBP " control arms ?
Thanks in advance to the person who knows this answer.

I used to think that they were offset to the rear of the car (to get more camber). They are actually offset 90 degrees to that. As it was explained to me, it allows for proper camber setting on cars that have a weakened crossmember.
This is if you buy the shafts only. If you are getting the upper A-arms from VBP, the arms themselves allow for more caster.

Finished 4 Today
i already have the have the upper a - arms installed on car.what I was trying to find out for was so that I could rotate 180 degrees to gain more clearence to mount the a support bar to the car.I will call
" VBP" on Monday to find out.I just finished the install on the (BeCool ) huge raidator,refabricated electric fan mount, installed serpentine pulleys, fabricated upper hose to clear belt, adjusted exhaust as it runs under the rear -end,remounted spare tire carrier,fixed heat riser tube on intake,washed,vacuumed car out fast,put the top down,going to take a shower,and go get a bite to eat,then head to the local car show tonight.

What are you trying to do?? If you want more caster the hole can easily be milled 1/4 inch towards the front to allow the arm to be pushed reward increasing caster.
The offset arms allow more camber, negative camber that is, or positive depending on which way you put the arms in.
So if you want more camber without shims the offset arms work. If you want more caster, mill the slots.
The arms do not need to come apart to cut the hole for increased caster.

thanks norval,but you mis understood what i said.i know i am dealing with camber.when i installed the upper arms i had the offset towards the center of the car,and have a good stack of shims between the frame and the mounting arm,now what i need to know was how much
these things are offset off the centerline.I want to remove as many shims as possible,that is why i wanted to know what the offset is ,so i can rotate the piece that attaches to the car.anyway i have it together now with the spreader bar,and have not altered the camber .I will call on monday to ask what the things are offset off centerline.

You should be able to just place a level against the wheel and tell the offset. I assume you are trying to pull the top of the wheel IN to create more NEGative camber. The stack of shims would indicate that you need to pull the top of the tire in and it would also indicate that you have the shafts in wrong.
If you install the shafts backwards it pushes the top of the wheel out causing you to need alot of shims to offset the offset.
I did an alignment for a guy recently that did the exact same things.
Offset shafts in 180 degrees wrong and a pile of shims.
Use a normal carpenters level and you want the top of the wheel about 1/4 inch maximum in when the level is plumb.
