From reading the many questions asked by others, some of you are going say "not again" but here goes. I have an 85 IROC and am looking for aftermarket rims to replace the originals which I plan to keep with original tires intact. However, the more I look the more I get confused. Are spacers a good thing or should they be avoided. I would like to go 17inch rims for greater tire selection but maybe in should just get a set of used IROC rims 16inch refinished. Any advice our there would be appreciated. Any recommendations on offsets to avoided spaces or even recommendations of rims would be helpful. Thanks.

 

What do you use your car for

 

I use the car for pleasure only, probably less than 500KM per year.

 

17x9 all the way around should be fine

 

best of both worlds, 17" IROCs, no spacers. check HAWKS, look really good too....

 

traditionally spacers are usually used to make wheels fit that weren't made for the car. For example c5 corvette wheels. However if you are buying new wheels from a vendor you'd be better off getting ones with the correct offset and spacing to fit the car. Spacers are not a bad thing they are just one more potential weak link. I have them on mine to make my Corvette wheels fit and i have no issues. So either way you are going to be fine but if you can do without them I would.

 

I am trying to put C6 wheels on my car and where do you guys get the spacers from and what size.

 

Benjamin1, here's my two cents.
1) Stock Irocs are relatively cheep, look great, and fit an affordable 245/50/16 tire no problem. They are 0mm offset up front and +16mm out back.
2) many guys run (4) 0mm offset front wheels, to help rotating tires, though you'd have to piece together a set of four which can be tricky. The rears will stick out 16mm farther that with stock rear wheels, and actually looks darn good. Doesn't look funny at all, and most won't even notice.
3)...along those lines, I'd shoot for a 0mm offset on all four wheels/corners.
4) check out Hawk's Motorsports. They sell several different sets of 17x9.5 wheels with 0mm offset. Old Irocs, New Irocs, GTA's Firehawks, etc. etc. They fit a 275/40/17 tire.
5) Aiming for 0mm offset....if you find a wheel with +50mm offset, then you'd need a 50mm adapter. -measured in inches, get as close as you can.
6) Just a little terminology... Spacers are sandwiched between the wheel and hub, and aren't mechanically attached to either. Adapters physically bolt to your existing 5 lug nuts, and have 5 NEW lug nuts of their own. Adapter bolts to hub, wheel bolts to adapter. THICK spacers are bad. THIN adapters are bad. Spacers are usually for fine tuning. Typically thin. .25" or less. Adapters are for adapting a wheel from one application to another.

What style c6 wheel? Search what the offset is. They're typically pretty high offset. Probably over 50mm some as high as +70mm I think. Find the offset of the wheel first. Let's say for example it's a +55mm offset. Assuming you're aiming for a 0mm offset, then you'll need an adapter (not a spacer) that's as close to +55mm as possible. Adapters are measured in inches, and 55mm is 2.16" inches, SOOoooooooo.....you'd want a 2, maybe 2.25" adapter. Find the c6 wheel offset, go from there.
