Already done the Akebono BBK? Please chime in on fitment question.

Postby EX37 » Mon Jan 15, 2018 9:34 am

Hi guys. Hoping some of you who have already completed the Akebono BBK can give me some insight. I got my setup - new front calipers, pads and rotors- installed on the driver side and tested the wheel fitment. No go. Not even close to fitting. My EX37 has the factory 19” wheels and I’ve added 12mm spacers.

I’ve always understood that it fits with the factory 19’s. Any thoughts?

Haven't installed the kit. Just recently purchased a QX50, and have been looking at brake system upgrades. I did notice that one of the suppliers of this kit stated that aftermarket wheels are required, and they provide a pdf file of a template to check clearances.

Concept Z Performance was the supplier.

That’s perfect - thanks. Wonder why their kit requires the custom brackets? That’s the first I’ve seen of that.

Regardless, I’m going to print one off and test the template.

Is the Akebono kit different from say, a rockauto caliper/rotor/pad kit from a G37XS ? The rotor size is 350/330 (I think) and the calipers look similar. And they must fit behind 19 inch G wheels, yes? Wasn't aware there is that much difference between a QX/EX 19 inch wheel, and a 19 from the G model.

Sorry guys I'm really busy these days. Hope this helps:

Adapter brackets not needed. My boyfriend bolted them right up.
HOWEVER some trimming or removal of the brake dust shield is required for the rotors to fit.
Mine fit under 18-inch M37 winter wheels and of course my 19-inch 370Z wheels fit no problem whatsoever. :dblthumb:

Do you know what the offset is on the m37 wheels? My factory 19’s aren’t even close, which was a let down. I downloaded the template from concept z and even with the 12mm spacer, I’m a half inch off.

The spoke shape on those z wheels you have are really angled out (not sure how to better describe it) where the 19’s are more arched on the inside, which is where they hit. Wish I knew someone with the 19” G37S wheels that I could test fit. 😕

As far as the Rockauto calipers go, they’re the same and should work fine, based on what I’ve been able to find.

Saw this caliper setup behind a set of factory 19s. A G37 coupe with the 15 spoke wheels. Offset is 43, width is 8.5 inches. Offset on the factory QX50 19s is 47. Must be a big difference in spoke curvature. I have both wheels, but no tires mounted on the G wheels yet.

Does anyone know if you need new brake lines? or the oem one on the car lines up just fine? if you do need new brake lines which model to get them from?

also, the rotors are 355mm for the sports brake right?

i'm wondering if anyone tried the oem 18 journey wheels with a bunch of spokes on them, wondering if that will clear the calipers, they seem to be really flush on the outside not much of a curvature inside.

You dont need new brake lines, just a new banjo bolt ( shorter ).

Can someone enlighten me which year/model Akebono BBK will fit in the 2016-2017 Infiniti QX50? I have a 2017 QX50 AWD with the factory 19 inch wheel package. Anyone know if the front BBK will clear the 19 inch factory wheels? I've done several biger caliper swaps in the past with other car brands so don't mind tackling this project if its a direct fit (i.e. no need for wheel spacers or modified caliper brackets). Thank you for any help.

Front wheels will not fit, you'll need spacers.

Thanks Dzionassi. But can anyone point me to the year and model of the Infiniti the Akebono BBK will be used from? I.E. 2010 Infiniti G37 or something else.... Thanks.

Dzionassi - Is your QX50 still on the factory stock 19 inch wheels and are you using wheel spacers? If so, what size spacers? I'm assuming the brake rotors to use is any of the G37 ones, right? Thanks for all your help.

Thanks Dzionassi for your help. I plan on doing this BBK once my factory warranty runs out. I saw in your signature that the you have the Hotchkis say bars installed. I'm assuming you got the ones for the AWD 2008-2013 Infiniti G37, right? Its direct fit with no modification? Thats another mod I will partake once warranty runs out.

Yes, 22443 Hotchkis, and yes there is basically no modifications need, had to use 4 washers (2 per side) for plastic mud guards ( wind deflectors)...
