Hi. 2013 Skyactiv, and putting on '06 RX-8 wheels with 235/40/18. Front is spaced well, but was thinking of bumping out back with a 5 mm spacer.

However, I am concerned that there will not be enough of the centre hub protruding beyond the spacer to go into the wheel bore to keep it centred (aka hubcentric). I don't want the wheels centered off the studs as that is likely to lead to vibrations.

I suspect to provide good centering capability, it the centre hub will have to protrude at least 10mm beyond the face of the rotor. This would mean that there is at least 5 mm past the 5 mm spacer to go into the wheel centre bore to centre it.

Does anyone know how much the centre hub protrudes beyond the face of the rotor?

Thanks in advance.

Jack yours up and pop a wheel off and measure it ?

Thanks for the insightful suggestion. My question was in hopes that someone had already run into this issue and could share their experience with out me getting out a jack below zero temperatures to check it out. Isn't that what these forums are about?

I am an avid participator and former mod on several auto forums, and responses like this are what turn away new forum members who themselves can contribute to the community. There are WAY TOO many Mazda, and Mazda 3 forums in particular, to be doing that.

I have done my share of DIY instructional threads on everything to re/re parts, installing aftermarket, modding etc with detailed step by step instructions and pics, and as a new Mazda3 owner, fully plan to do the same with our 2ndary vehicle (got lots planned). However, "welcomes" such as this don't give me the warm and fuzzies about doing it here when there are so many other forums out there. Nevertheless, I won't stereotype the rest of the mazda3revolution community with your less than useful post.

In response to your suggestion, I most certainly will jack up my vehicle to make that determination when weather permits, presuming a fellow member does not share his/her experiences/knowledge before me doing so.
