Oook....so I was looking at wheels on AM and my boyfriend who drives a camaro wants them for his car. Obviously this is a problem because the bolt patterns on a mustang and camaro are very different. So what he wants to do is get adapters to go from his bolt pattern to mine, which is easy enough...our question is how do you figure out whether or not the offset on the mustang wheels will work on the camaro? The offset for stock camaro wheels is 55, the offset for the new wheels is 30, and the offset of the adapters is 31.75. Anyone know how to figure this out? Btw, its a 1994 lt1.

 

Boyfriend may need a mustang to put those wheels on or $$$ to modify some rims.

 

Wheels+Adapters. Your total offset from hub will be 61.75. This is in millimeters, or mm, btw.

There's way more to it than this, however. You don't mention the rim width. If you're moving from a 8" wide rim to an 8" wide rim, then your outer rim lip will be 6.75mm farther out, or about 1/4", and the entire wheel will shift outwards by this much. This is because he'd be moving from a 55mm offset to a 61.75mm offset.

HOWEVER, if you were going from a 7.5" to an 8.5", the numbers are way different. IN this case, you have to add the .5" each side to the rim, THEN add the new offset. .5" in mm is 12.7mm. So you add 12.7mm to the above 6.75mm, and you get 19.45mm, or about .75" movement of the outer lip outwards. The inner lip moves 12.7mm "in", but then back "out" the 6.75mm, for a total movement of 5.95mm or about 1/4" towards the inner fender.

Clear as mud, right?

I second this. This is pretty much spot on. And from what I remember about those model Camaro's is that the wheels are pretty recessed so there shouldn't be a problem but sometimes you never know till you get them on the car. Best bet would be to find some wheels with a comparable offset as the ones on AM and try them out on the car and see how much room you have to play with. You can also take a carpentry type level, a 48 inch one to be exact and hold it against the outside of the fender level horizontally. Then measure to the most outward point on the wheel/tire. That will tell you how far you can come out without sticking out past the fender. Even then that may not look great even if its perfectly even with the fender. And of course you will need to be proficient at converting inches to millimeters and vice versa!

 

Which wheels by the way?

 

These!! Thank you guys for your help! I thin k he is going to get them

 

they make those style wheel for the camaro. I seen it in person.

 

Where?!?! We looked and couldn't find anything...

 

They most certainly do. Although they weren't nearly as cheap. As a matter of fact I ordered those wheels last week and they will be on my car next thursday. But I do believe that these are the cheapest ones in that style. Though making them fit may be more trouble than it's worth. This site has some awesome wheels for Camaros that are very affordable and the right offset.

I got it right? Heck yeah! All those nights studyin' wheel fitments for Awesome paid off. Sweet.

/knew it'd come in handy one day.
//And all off the top o' my head.
///Nice wheel choice, btw... but get 'maro ones, it's a better deal.

 

BINGO! I found these! And I think the offset will work. Based on what I've read these have the offset you need and the bolt pattern is right! Not a bad price either....

Wow! Those are $250 a wheel, no tires! Thats a lot!! Im pretty sure he still wants to go with the AMR wheels in 18s

 

Those are sweet.

 

I think they are pretty sweet too! but its not up to me lol I really do appreciate the help

 

I understand that they are more money. But you have to look at the big picture here. Those wheels from AM are going to cost $1200 or more with tires. Then you will need to get hub centric spacers that give enough room to clear the original studs and not stick out beyond the fenders or look weird from the back. The reason I said hub centric is because you don't want to have problems with shaking or worse abnormal wear on the tires. Then you have to find spacers that change the lug pattern from 4.75 to 4.5. I just looked on Ebay and there were none. Regular spacers with hub centric rings would also work but they are about $100 a set plus the rings. He will only save about $300 dollars give or take $100. Seems like a lot to go through. But hey, I definitely know the value of $400 and if the risk seems worth it, go for it!

AM Wheels
Wheels & Tires = $1200
Spacers = $200
Rings = $50

Ebay Wheels
Wheels = $1096
Tires (AM) = $750

 

That post I just wrote seemed kind of douchey. Your welcome for the help and I'm really not being a douche. LOL Just trying to help. Sometimes the true intent doesn't come through correctly on these forums! Hope you didn't take it the wrong way, if so, I apologize!

 

Not douchey at all. He found the spacers they are about $150 for the set I think he said, the beamer wheels will fit, I'm just not sure how he will like them compared to the AM wheels...I guess we have some thinking to do But you definitely have a good point, I keep making fun of him anyways for putting Mustang wheels on his beloved Camaro

 

If he does it please post pictures so we can chuckle a little to! Just kidding! Those are some goo looking wheels, I don't blame him. And compared to the others the price can't be beat. That't why I pulled the trigger on these last week. Can't wait till I see the UPS truck Thursday!

 

Not going to work.

If you have a wheel with 30-mm offset and an adapter with a 31.75-mm thickness, the effective offset will be -1.75 mm.

Don't believe the two posts above mine saying the effective offset would be 61.75 mm.

If your boyfriend is hell bent on using those wheels, a correct PCD can be drilled granted that the mounting pad has sufficient area. The use of steel lug seat inserts is highly recommended. The mounting pad can be shaved a few mm to increase the offset at the cost of strength, but it would not get significantly closer to 50 or 55 mm.

All these things considered, by then a set of wheels from Forgestar would be more feasible.

 

I would say if he really want those wheel he should do it right. Its alittle more money but its doing it right to buy the right wheel from the start. Do not buy three or five parts to do the job of one. It will be far less of a headache now and later on.
