View Full Version : Would 5x120.65 work?

The guys at VWVortex (yeah, I know) are telling me it should. There are some awesome rims out there for old Corvettes/Camaros, but they are all 5x120.65. The difference is only .13mm per hole, but I know with rims any difference can cause vibrations and problems. I have a feeling it might mount up on the studs but won't center correctly once the lugs are screwed in.

Your math is a little off.

The 120.65 mm part is for diameter of the hole centers. So, for each opposing hole it's 0.65 mm / 2 = 0.325 mm concentric.

That's the nominal issue. The real measurement, I have a very vague idea. Might want to talk to those who actually deal with this stuff. I'd try a member by the nickname toddman35. He manufactures spacers/adapters.

I also have wondered about this.


EDIT: Holy crap, small world: I was browsing VWVortex's wheel classifieds and I saw your name pop up. Weird. I saw a set of Gotti's on there that wants me to buy them.

I made a thread awhile back about these:

With the right sized tire, they could look very good IMO. Plus I think sets go for ~$200.

Yeah I saw those Hayashi's on Vortex. Pimp as hell. I've only seen those on E30's.

Word. I think I am going to buy some cheap ass set of 5x120.65 rims just to test them out before I drop big bucks on what I want.

let me know how that goes... sorry to make you a guinea pig ;)

You're dealing with about 0.012" misalignment per stud. I'd be inclined to say it will work, but will be putting additional bending stress on the stud. There is such a high safety factor with 5 studs though, that I can't see it being an issue.

Keep in mind that your hub probably has a tolerance of +/- 0.003-0.005" and your wheel probably has a bit more than that, and it will change slightly as the wheel heats up due to the disimilar metals. So even a "proper" 5x120mm wheel on a 5x120mm hub isn't going to be "dead nuts" on.

been there, both ways. I have BMW 5x120 SSR GT3's on a WS6 for the last 5 yrs, if you dont tightened the lugs semi tight while the wheels are up off the ground, they will slightly shake at highway speeds, other than that.. they are fine. In the meantime, i had camaro SS 10 spokes mounted on a bmw bolt pattern, same dilemna... occasional slight shake at highway speeds..

What it comes down to... both ways, i did not like it.

I have seen those on a BMW!

I've got my eyes on some other things :D

It would help if you had the specs of the wheels. Yes, they will bolt on but offset is usually to high.


BTW If the wheels are BBS RS off a corvette I'd advise against trying to fit them on a BMW.

Personally, I would recommend against it. Because of the shape of the lug seats, they're going to put a pretty big side-load on the lug studs/bolts... They will probably be OK for a while, but it only takes one failure to be a serious problem.

The .013" deflection of each stud (radially) is more significant than it sounds, and the loads it places on the wheel stud/bolt are not in a direction it is designed to carry any load in.

Just my 2c. YMMV.

Can't beat first hand advice. Thanks so much man.no prob man! glad to be of help.

Just joined. Have to add my 2 cents. I'm looking for rims too and have voted against the non BMW 5X120 rims. There are people who have done this but I haven't found one who said they worked perfectly. All vibrate and that small vibration starts screwing up the drivetrain, wheel bearings, CV joints etc. If your going to do it, do it right. Buy quality GM rims and have them machined correctly at a rim shop. I know the ones in Cleveland charge $25-$40 per rim. They cut just enough off the holes to make the nuts seat properly. I like the BMW rims myself so I'm sticking with BMW.

I bought another set of BBS's last night so I am putting the 5x120.65 rims out of my mind. But I appreciate all the input.

every modern car does.. some older cars use the studs/lugs to centre the rim on the hub

the issue with wobble bolts is most vette/camaro whatever wheels require pretty serious spacers. I have a set of 38mm spacers that are 5x120 both sides, but the hubcentric lip on the wheel side is 70.5 to fit vette wheels perfectly. Didn't have any vibration issues with staggered 17" sawblades on my 6'er

I have an interesting set of 16x9.5 vette wheels I want to run now, might have to get 2 or 4 of them skinnied to 8.5 in order to be able to fit them on my e30 though.
