I am going to pick up a set of bottlecaps latter this week to throw on an EG project I just finished and I was wondering if they were hub centric. And, if so, anyone know what size ring I need to make them fit?

Thanks in advance for your help.

 

From what I could gather, they have a center bore of 57.1mm compared to an EG's diameter of 56.1mm. You'd be hard pressed to find rings that small. If necessary, they would probably have to be machined. I'd just put the wheels on, and see if there's any wobble.

 

I had hoped they were actually smaller, so that I could machine them out a bit and have them fit perfectly. If they are hub-centric and are a mm bigger, it seems odd that people don't have fitment issues. I guess on lighter cars lug-centric wheels are not a problem.

 

I am picking them up tomorrow afternoon. I'll have to measure them when I get them home. I think all bottlecaps are from E30s.

Its hardly light with me in it (2,815 lbs), but my GSR is daily driven with 5Zigen wheels and no hubcentric adapters. Hasn't been an issue in 2 years.

I also auto-x and do HPDEs on Rota Slipstreams, again, no hubcentric adapters. No issues in 14 auto-x events and 3 HPDEs.

I kind of think the whole hubcentric thing is overrated.

On the other hand, when we got wheels for my GF's car, I made absolute certain that we would have adapters for them. But that was mostly because I hate wheel bolts (and hate them significantly more without a hubcentric mount), which the Audi A4 uses. If I can't set the wheel on the lugs while I fumble with lugnuts, I at least want to be able to set the hub in place while I fumble with the bolts...

Are you kidding? That is definitely light for a car. Almost everything on the road is over 3K without passengers.

Accord = 3500
TSX = 3400
Camry = 3400
Maxima = 3500

Those are all small to mid-size cars. Hell, my little C class Mercedes is probably 3400 lbs.

Well, compared to my 1,750 lbs Triumph Spitfire, those are all grotesquely overweight vehicles. Sigh, does a Camry really weigh in at twice what my weekend cruiser weighs?

But yeah, these days, your average passenger sedan and your average American have 1 thing in common, they're both carrying around enough excessive (and unnecessary) weight to be a danger to themselves and those around them.

 

i agree on all the specs that were given above and i have also rolled on multiple sets of different wheels w/o using hub rings and really, the only times i felt vibration was either due to warped brake rotors and /or misbalance of tires. having hub rings is a good idea but then if you roll on them w/o and it doesnt vibrate then i say you are good to go...
