Wheel Spacers?
As for hub concentricity - it's always best to do so, but if you get a good set of quality spacers and the wheels are true, you can still have good wheel to hub concentricity without them, but plan on having a damn good wheel balance done.
I had Midamerica 3/4 , i had to sell them because those were made without
nut recess,and they fit with the 17" stock vette wheels but not with my Fikse FM5 set.
I bought a set of 1" from the vendor i posted above and they are just wonderful
Im running 1.25" on the fronts and 1" on the rears ...and it does not stick out at all
They are JUST PERFECT.
My FIKSE have C5 offsets...i went thru everything and the guy linked above has the best price and quality adapters

Get the ones im telling you
i won't steer you wrong !
Not hub-centric but they work just fine !!!
$ 119 for the 4 pieces , complete set !!!
GET THEM HERE
I have a pair of 20mm hubcentric spacers I ran for 2 years on my 1990. I changed wheels and don't need them anymore. I also have the longer studs to work with them. the adapters are what Calderone linked. Everyone has their preferences though. with my current wheels I am running a 1/4" spacer with longer studs on all 4 wheels.
shoot me a PM if you are interested in my Spacers and Studs.. I will give you a great deal on them
Calderone do you have a late Dana 44 swap like mine? Does anyone know What the width difference on the knuckle to knucke is on a 88+ to an 84-87?
I just looked and the front wagon wheels have a 56mm off set, and the rears are at 61mm right off the wheel. So that puts me at 18mm / 3/4" difference for the front and 23mm or just under 1" for the rear. Does the late Dana 44 make up this difference? Is this how my car looked stock?(I cant remember) I think either way I want to space them out like Calderone. I just need to know If he has done the rear swap like me then I will order exactly what he did.

PS Is there any more comment on the non hub centric spacers????
Just had a question in regards to the adapters. I've been told by several Tire and wheel shops that its unsafe to use the wheel adapters and wanted to check with you guys to the truth to this. They said that they never recommend them because the bolts tend to break off and said that its best to use spacers. Thoughts, advice ?
thanks
this is what i had bough before i heard all this

this is what i was told to get instead but i think they are too thin and would have to get 2 on each wheel but wont i run out of bolt space ??

The difference in the offset was in the hubs and spindles I believe.
Hey 87 go and install your rims with no adapters....then measure how much do you want your rim to go out.....then buy adapters going by what you measured.
I've not seen wheel stud failures for many years and those involved "cast aluminum" adapters that were used to adapt 5 x 4 3/4 to the early (very early) VW hubs. Technology has changed and most quality adapters/spacers are done in "billet" material.
There are "thin" spacers that are still cast materials but I'm assuming most that have posted here understand the product being discussed.
I use billet "pass through" spacers that are 18mm to run 50mm 11" wheels on the rear of my ZR-1. Mine were done to my specifications and are both "hub-centric" and "bolt-centric". Mine were substantially more expensive than those in the links that have been posted. I'd still spend the additional "MONEY" for mine. My spacers fit the hub better than my OE wheels and the adapter is a better fit to the wheel.
Mount the tire/wheel package drop a plumb-bob, measure and do the buy!! You need to satisfy only "yourself" with the fit!!
Thanks again guys..
PS Calderone if you can still post some specs on your wheels... size, backspacing, tire size. That'd be great.
