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 ).
