Quick question for whoever knows...i hear the Infiniti Q45 brake calipers fit the nissan sentra ser b13 making it a dual piston caliper set up. Is this true??? This would be great stopping power for the Gti-R SR motor swap i'm doing soon. Please help.

Some have recently got the Z32 brakes to work, so with that, you could get the q45 brakes to work as well. But this isn't a easy conversion.

"Z32 calipers: I highly recommend to get the ones from the 1990 N/A 300zx, as they fit better in our little cars, and they wont need a massively thick rotor.

U13 Altima brake rotors:They have the same diameter as the Z32 rotor (280mm), its a little bit thinner though (22mm vs the 26mm of the N/A Z)

U13 Altima master cylinder:It will be helpful, considering you have in one single wheel, the same amount of pistons you had in the whole car before lol

And this is the heart of the project, nothing makes sense, and nothing will fit on your car, unless you have this:

B15 Sentra Steering knuckle and hubs:Yes, this means your front wheels will be now 114x4. But the Z32 caliper and Altima rotors will fit, right in. No adapter plates, no custom job. But most of the aftermaket wheels have 100x4 and 114x4, as my enkeis.

Optional parts:This depends on the wheels you are using, due to spoke design of my wheels, I had to run spacers now.

Unfortunately, is not that easy, while bolting everything in, we found that due to the B15 knuckle, the rotor needs to be reduced in diameter 4 milimeters, or otherwise it will hit the caliper. So you have to take the rotors to a machine shop before bolting everything in."

Another route is the nx2000 brakes with the fastbrakes 11.75" rotor upgrade.

The nx2000 brakes are a tremendous upgrade over the stock brakes to begin with. Now those brakes with a 11.75" rotor and some good pads and steel braided lines would stop the car just as well as the z32 brakes and probably cheaper as well.

the Q45 calipers will not fit I have tryed myself to get them to fit

If you use the B15 knuckles they should fit, especially if the z32 brakes fit. The 240 guys use z32 brakes and q45 brakes as upgrades.
