That second number the hub diameter listing. Go measure your hubs.

Thanks I will check that. Hopefully it's going to be one of these two.

If I remember right - our (FC) hubs are a bit less than 60mm. So the 59.5 sounds exactly right.



I think the 67.1mm is the FD hub size.



So in this lies a problem. You are putting a wheel with a 67.1 mm hub onto a wheel with a 60mm hub. That is a dangereous combination, as your studs will be bearing all the weight of the wheel instead of the bub which should be doing that job. The consequences will be broken studs...and I hope for your sake that they do not break while in motion!!!



I suggest that you also invest in a pair of centering rings. Sorry for the "evil" link...but that thread is extreemly informative for those who do not run stock wheels.

Is it why there is a kind of lip on the spacer shown in this thread ?

Yes. That lip is what holds the weight of your car, instead of the studs. That lip is what the above diameters is refering to.

Ok, so I should get the spacer with 59.5 mm lip and put a ring over it to get the 67.1 mm of the FD wheel ? Did I get it ?



Thanks a lot sunshine!

If what FD3S-wanted said is true, where would be the best place to order that equipmant? I don't want to get the wrong thing.

Today I checked the hub diameter and it's 59,xx mm. I also put the FD wheel in the FC hub and it fits perfect, no need of centering ring.



So I need this spacer: H&R SPACER FORD/MAZDA (5:114.3/59.5) 25MM .



Am I right ??
