Camaro SS Rims on 73-87?

[blk81shrt]

I found these rims in a local add, I got to thinking that these would look pretty sweet!

They are 17" but I dont know the offset. Does anyone know what the offset would be and/or if they would fit?? The ad said they came off a 1998-2002 Camaro.

Thanks!

i think camaros have the 5x4 1/2 bolt pattern. could be wrong for these years, but i know its correct for the 3rd gens.

[raggedjim]

Wrong bolt circle and bad offset...

[LONGHAIR]

I think it is actually 4 3/4" not 4 1/2"....Either way it won't fit a 5" patterned truck.
S-10 yes, full size truck ....no.

Would it be possible (without a "money's no object" dedication) to come up with a set of rotors/drums (or rotors/rotors?) with a custom pattern to them?
I would suppose if you converted to rear discs you could come up with something there but what about the fronts?

It would open up a whole 'nother world of used rims.

I have heard that some of the 70's G-10 chevy vans had the 5 x 4.75 disc brake rotors and the spindles used the same ball joints as our trucks... I haven't tried it, but it may be worth looking into...

yeah, that sounds right. been away from camaros a little too long it looks like.

They are the 5x4.75 car pattern but that's easily changed w/a little money. Rotors can have the hubs machined down to the correct dimension & then re-drilled for a car bolt pattern.

The other issue not mentioned yet is the off-set. The f-bodies use a bunch of back-spacing that won't work for these trucks. There's a way around that too. Billet adapters could be used to reduce the overall amount of back spacing (basically like making the track width wider which would require a wheel w/more BSing).

So if adapters are needed, they can be purchased in the necessary width to correct the BSing & change the bolt pattern @ the same time.

[kevinr1970]

So If I am understanding this correctly, the BS of the Camaro/Firebird (what about Corvette?) wheels would require the use of an adapter to get them centered correctly anyways, and those can be had in a 5x4-3/4 / 5x5 pattern?
Hmmm....

those woudl look kinda hott too bad thou...

[blk81shrt]

So how many people actually run spacers? I was talking to a guy at the local performance shop about this and we came to the conclusion that anything that would decrease the strength of a stud would be bad news!

Think about it, all the weight of the wheel being pushed down on the end of a bolt. Then add in rolling mass, and centripedal force! Seems like asking for trouble flying down the freeway!

Spacers & adapters are two different things. An adapter bolts to the existing hub just like a wheel. The wheel in turn bolts to the adapter. You're using 2 different sets of studs not putting the lug nuts on the end of one longer set of studs.

Yes, adapters can be purchased in a 5x5 to 5x4.75 pattern (that's what I used for the TT2's on the back of my 74).

Scotti is right on. You could probably swap some suspension parts and make some of the camaro brake stuff work with some fabrication. But to do it "cheap" (which should still cost a couple hundred bucks), and since you should have plenty of room--adaptors would work. I used like 3 inch adaptors on a 3640lb, 400-500 hp Buick for five years with no problems. They were on the rears at that, and I made many many 15psi launches. I think the manufacturer was Skulte. Just make sure and get the appropriate length of ARP hardened studs to be on the safe side.

I'm lookin in to this as well, my bro has centerlines from his 80 camaro he'd give me.

[Bad Karma]

I used a pair of aluminum 1.5" adapters on the front axle of a rockcrawler with 40" tires. Never had a problem with them.

To be specific these were "billet" aluminum adapters, not "cast" aluminum adapters...

[Bad Karma]

Correct.

If you are doing it to use inexpensive wheels, you're probably jumping over a dollar to save a dime. But if you really want those wheels, it's pretty easy, just cost a couple hundred to do it.

Or you're making an investment in a set of wheels that could fit multiple vehicles thus increasing the potential to re-sell them @ a later time.

My TT2's not only fit my truck (w/adapters), they will also fit early GM a-bodys (chevelles, gto's, olds, buicks); f-bodies 70-81 w/o mods, 67-69's w/mini-tubs; etc . . ...... You get the picture though.

With more possibilities, they'll only be easier to move.

That rims will fit in a s10 trucks but in the full size trucks won´t fit.. I saw a 72 camaro with a s10 rims....

If you re-read the posts, they will fit (they just won't be a direct swap). 17x9" SS wheels (and the similar T/A 5-spokes) came from GM w/+50mm off-set & have a car pattern. Off-set to back spacing calculations indicate:

9" wheel + 1" (lip dimension) = 10" total width
10"/2 = 5" total (5" = C/L of wheel)

5" + (50mm x .03937) = 6.9685" (the off-set converted to BS in inches)

Since 73-87's typically use an 8" wheel in front w/anywhere from 4-5.25" BS-ing, we'll use the medium BS number of 4.5". If you increase the wheel width by 1" evenly, that suggests 5" BS needed for a 9" wheel.

Using those SS 10-spoke wheels, you could add a 5x5 to 5x4.75 billet adapter that is 2" wide. 6.96" (calculated BS) - 5" (required BS) = 1.96 (amount the wheel needs to be adjusted). A 2" adapter would be the closest to that dimension.

Clear as mud?

[LONGHAIR]

And that would add at least $200 to the cost.
If you are getting a good enough deal on the wheels, it's not that bad.

Good point. I have some adapters, and I've swapped brake drums to change to a more popular bolt pattern on another vehicle.

Here is the reply to my email asking about BS

I still have them for sale, Rims, centre caps, lug nuts and lug covers. This rim is off my 2002 Camaro SS it fits all 4th generation Camaros. It is a GM style rim that will fit GM bolt patterns. As far as offset is concerned it is 4.5 inches. This rim would fit older Camaros without spacers and many other GM cars. It can't be used for FORD and imports.

This rim would even fit a 60's Camaro bolt pattern but it has too much back space for the fenders. I own a 69 Camaro and checked in the Winter so I know it won't work without modifications.

So scoti you were right, 4.5 BS, great calculations! So if i did get the 2" adaptors they would fit? It is something to think about- I think they would look real good on my truck. Maybe I will get a pic photoshopped.

So the asking price for these wheels is 500. No tires- anyone think thats a decent price for a 17" rim? Tires wont be cheap either- well a lot more pricey then my rallys!

[SCOTI]

I'll go out on a limb & say those wheels do not have 4.5" back-spacing unless something has been done to them. I have the GM equivalent on our '02 CE-T/A (17x9" WS6 5-spokes) & know it's greater than 4.5" BS on them.

The pricing doesn't seem to be all that great though for your situation. Take that $500 plus the $250-300 in adapters & see what you can get for $800.

Now, if you were getting them for much less it might be a different story.
