Hi guys I recently bought a set of 6 pots Brembo off from the used market and I am wondering if a 6 pots Brembo Caliper fit in the rays 18' wheels? Any members here using a 6 pots in their 18' wheels? Can you show me photos? Thanks!

 

Should be a 355mm rotor, you can get some 17's over them

 

So 18' will be fine fitting the 355mm rotor and the 6 pots Brembo right?

 

Yup, but you have to worry about spoke design.

 

They fit fine, these were under my 18" OEM standard wheels.

 

Your wilwood 6 pots seems smaller than my Brembo 6 pots! My 6 pots model (18Z) are off from the Porsche Cayenne! Haven't install yet not sure if it will fit on my Rays 18"???

 

This is the Brembo model I am talking about!!!!

 

I really hope you're not trying to put those baller brakes on OEM wheels? If so they might fit or will require a spacer.

You should really be going for aftermarket wheels, otherwise why go through the trouble and then just run OEM's

 

Yes I am using rays already! Just wondering if my Brembo 18Z will fit the 18 inch rims???

 

Have you placed the rotor/caliper assembly on the hub to see if the mounting holes play nice with each other. Bear in mind that the mounting holes are for 16mm bolts rather than standard M14x1.5 bolts the Z uses, so you'll have to sleeve the mounting holes of the calipers. That's been my only gripe about these calipers thus far- I'm not entirely sure the bolt holes don't interfere, or cause problems when you try to clock the caliper down to 9 o'clock (like you should). Admittedly, I don't have a set to look at.

I do like these calipers though. They're the right size (piston area) for a proper upgrade. With a 345mm rotor up front and the 370Z rear rotor put the bias within 0.1% of the OE track brakes. Using the OE Brembo rear (which, diameter-wise is better suited to the rear Cayenne caliper) puts the bias about 1% forward of the Track setup, which may be a good thing depending on the tire stagger you're running.

Hydraulically, the AMG SLK55 mercedes calipers are the same size, but radial mount and equally cheap if you know where to look.

Hydraulically, they are about 1.8% larger than OE standard brakes, which is well within what will work with the stock master cylinder (for reference, the 06+ standard brakes are significantly larger area than this).

I used 996C4 calipers on my MR2 (which are very wide) and they easily cleared the spokes of a +32 wheel. Anything sub 20mm offset should clear with plenty of space. The 18Zs are probably 2-3mm wider on each side, from centerline (it actually really pisses me off that Brembo won't publish OE caliper drawings). The rotor choice might be more of an issue than the spokes. Depending on the shape of the wheel barrel, larger rotors may not work. Luckily there's a plethora of large diameter rotors with reasonable hat heights available with a 68mm hub hole (and the 5x112 bolt pattern rotors use large enough bolt holes to clear a set of 12mm studs in 5x114.3).
