I'm ordering custom spacers soon and I need some information. I've been looking around for a while, even came across this older thread, but can't seem to find a definite answer.

I need to know how far the hub protrudes from the mating surface (the hub height). Based on that thread, I saw 10mm, 11mm, and 12.7mm. What is the exact measurement?

Thanks

 

Can anyone confirm that the front hub height is 11mm and the rear hub height is 12.7mm?

Also, for anyone that runs/ran 8mm spacers, is a machined lip required or is there still enough room on the hub for the wheel to safely sit on?

 

Are you talking about the "stickout" amount that the wheel centers on?

As far as the 8mm spacer goes, I think you need a machined lip (hubcentric)to properly seat/center the wheel.
A friend of mine has flat 5mm spacers on his and it has minimal stick-out.

 

You should measure the hubs on your own car. The amount isn't the same for all years. I know that the 05/06 hubs are taller than earlier years. 8mm is an awkward spacer thickness for MINI because it will leave so little lip for centering. It's no accident that H&R spacers for MINI stop at 5mm, then jump to 15mm with integrated machined lip. The problem around 8-12 mm is not only that there's little or no hub sticking out, but it's also hard to add a machined lip because there's only space for thin metal underneath supporting the new lip.

Are the spacers for an aftermarket wheel with larger hub bore than the OEM wheel? If so, and you're making custom spacers, the best approach is to machine the spacer integrated with the centering ring in one piece. Then you can have any thickness spacer you want with no problem, and structurally it is way better than separate spacer and centering ring. I've heard of vendors that make them but don't have the information handy.

 

See, I'm at college at the moment so I'm not close to my car to do any measurements. Mini-madness makes 8mm spacers so we know it's possible. I'm running OEM wheels so I've come to the conclusion that a lip would be difficult. All I really need are the measurements of the hub heights. I'm pretty sure on 11mm and 12.7mm, I'd just like some confirmation.

In regards to miniconcarne's question, this is what I'm talking about.

 

You'll want this measured with the rotor in place. Or with any aftermarket hat in place if you are considering the fit of a BBK as hat thickness will change this.

 

Well, as I said the measurement isn't the same on all MINIs. I have a 2006 and bought SSR wheels from TireRack. The hubcaps didn't work because the hub height was too high and pushed against the back of the hubcap. TireRack said that hadn't heard of this problem before and when they checked they said the hub height had increased a bit. They sent me a different hubcap that required less clearance, which worked.

toddtce makes a good point. Are you getting spacers to clear an aftermarket brake? You need to know how its rotor measurement compared with OEM.

 

I own a 2004 r53. I did measure the rear hub last week and it looked to be around 13mm. So 12.7mm in the rear would make sense. I just wanted someone to confirm that. I need spacers to clear the collars on my coilovers.

But, I guess what it comes down to is I'll do some measuring once the coilovers actually go on.

 

Has anyone even ran 8mm spacers on their front hubs? If so, was there enough hub lip left to mount the wheel on?

 

Anyone? I know Mini-Madness sells 8mm spacers, but I'm not sure if they're only meant to be fitted on the rear hubs.

 

Very unlikely. *Although I'll confess to not being 100% sure.

When the iron hat is fit over the hub and a 3-5mm space is installed the support for the wheel is very minimal. Depending upon the hat (thinking bbk here) that spec may change some.

The wheel support is not the outer most barrel of the hub snout but the same register that the rotor is on. Look close at the witness marks on your hubs. You can also try doing it with some 1/2" flat washers and see what you get pretty easily.

 

I'm sorry, but you're pretty much speaking a foreign language to me. On an r53, the front hubs are 11mm. With an 8mm spacer, that leaves 3mm left for the wheel to sit on. You're saying that's not enough?

Also, the reason for needing spacers is to clear the collars on my coilovers. I'm not installing a bbk.

 

Not enough. The hub may measure 11mm but the wheel also has a chamfer that will negate the 3mm left over.

 

Ok, well now I'm just confused as to why mini-madness sells an 8mm spacer then. Why would they sell that size if it doesn't work?

 

I think larger than 5mm's they are designed with a hub-centric integrated into the spacer. Should not be a problem.

No one said it wouldn't work, just that there may not be enough for the wheels to remain "hub-centric". The more hub-centric-ness you have, the less chance for wheel vibration.

A friend that was running 5mm spacers had minimal engagement on his wheels, I machined him a set of 3mm, vibration fixed.

Sorry for any confusion.
