15" Bear Brakes and 6 piston calipers on a G35 Coupe

Has anyone run this set up?

If so, what do you think?

15" on the back? WOW!!! If you go that big with 6 piston calipers then finding rims to fit over those biatches would be a pain I'd think. My first impression anyways...just my .02 Why would you need that kind of stopping power on the back anyways? just curious...I think the stock sizes are 12.8 front and 12.7 rear?

I expect pretty good results from Bear brakes, but a few concerns I'd have about their brakes are in the photos, I don't see any outer dust seals on the pistons. Secondly, I didn't see any indication that they fit the correct piston sizes to match the vehicle's brake torque bias. Lastly, their rotors appear to be a 2-piece non-floating type. This means that as the rotor heats up, it expands, while the aluminum hat section will expand at a lower rate. This causes the rotor to cone. Though, I wouldn't be as concerned with it on a 15 inch rotor used on the street as the temperature change may be relatively low and thus, the effects of coning may be minimal. Of course, if this is only for street use, there is little concern to even need a brake upgrade. If race track use is planned, I'd be much more critical of all aspects of the brake system's design. Seemingly little things can make huge differences in performance, longevity and even brake feel/response.
