JD remember you going to have to put these front and rear. 2 sets. Don't know what your budget is..Also, since you are using factory wheels, they have a recess in the back of them in case your studs are to long, they will accomodate that. Some aftermarket wheels don't have this feature, therefore, length could then be a problem.

 

thanks bam..these are factory GM wheels so thats good to know,I didn't want to have to cut the factory studs down..my budget isn't endless,but I don't want to buy cheap parts either,especially in this case,and I think I understand what your saying about hub centric giving the extra support around the hub and not just the studs..makes sense..guess I'll get the higher dollar ones,the the saying goes "you get what you pay for"..thanks everybody

 

I thought only the rears need the spacer..........

 

mcm,the rear pretty much have to have the spacers,they fit but if you were to hit even the smallest bump the inside sidewall would rub on a bracket..the front fit and work fine,but they set in so far it just doesn't look good in my opinion,so I need all four..that's when I got excited about the ones I thought you were talking about for $55 a pair,but of course I was looking at the wrong ones,go figure..anyways if your wondering because I know you said you were looking to do the same thing,fronts aren't needed just personal preference

if I could figure out how to add a pic,I would show you what they looked like for the 5 minutes they were on the car..but apparently I'm not that smart...

 

Do me a favor...Just buy a set of 1" spacers first. See how they look on the rear. You will definetly need these on the front. Trying to figure out like someone posted above if you need 1 1/4 for the rear or will 1 inch suffice.

 

that's not a bad idea as this was one of my initial questions..how big of a spacer do I need..the fronts set way inside the fender,the back wasn't as bad but too close to rubbing for comfort..good tip!

 

so I just called ecklers and mamotorworks and they said their spacers are only 3/4 of an inch and that they wouldn't work on my car..I called just to see how thick theirs were compared to summits..called summit and they were pretty much useless for info..is anyone using these wheel adapters with 18in. wheels because this seems to be why they say it won't work on my car?

 

Trustworthy? Yes they can be!!!!

Before you consider "any" spacer/adapter purchase you need to determine just "exactly" what you need/want to use. The spacer/adapter dimension will change depending on wheel/tire combinations and personal taste in wheel/tire fit in wheelhouse! What suits the "other-guy" might not suit you!!

You don't just start buying 3/4", 1", 1 1/4" spacers!

If there was a "local" that had some 3/4" or whatever in your neighborhood you could borrow and "test"! Most people aren't that fortunate.

You need to become familiar with wheel dimensions and and how to measure them!

If you know exactly what tire/wheel combination is on your car presently and you posted that information along with all the information you can gather from the wheel/tire combination you'd like to use it would be much easier to help you!

How much do you know about the tire/wheel combination on the car presently? Do you know how to measure "back-spacing"?

How much do you know about the wheel/tire you'd like to use?

There's wheel information cast on the back-side of your wheels most likely. Post that information, the tire sizes and it will be easy to help you!

Regarding comments as to material! You can disregard information that directed you to "stainless-steel", I don't recall there being any or if there were they would have been VERY cost prohibitive and not found on the shelf at a "speed-shop"! Were there specialty ones? I doubt it but maybe!

The only steel adapters that I recall were for the early VW that had a bolt circle of I believe 205 mm and the adapter allowed the more popular 4 3/4" (120.65mm) GM wheel to be used. Early dune-buggies or whatever you'd like to refer to them as. These were stamped steel and weren't considered reliable. The cast aluminum that did the same were less reliable. You do NOT repeat NOT want a cast product!

You want billet 6061 or better, depending on the the wheel you're using and the hardware a "pass-through" hub-centric to the hub and the wheel is quite capable of being safe to thicknesses of probably 20mm. If the wheel you intend to use has recessed areas around the bolt-circle then the adapter style will work well!

I use a 16mm "pass-through" hub-centric to both the hub and wheel to use a 50mm offset 11" wheel on the rear of my ZR-1 and to place the wheel/tire where I feel it looks good. Many others have used the same or 18mm from the same vendor I used and are very happy. Mine weren't $55 a pair though!
