Ap Rear Caliper Selection

[fake400r]

Hi Guys,

Hoping some of the brake Gurus can help me out here.

I am about to purchase calipers for my GTR rear brake upgrade and have been looking at the Ap 5000+ series of calipers. Now the only suitable caliper for the rear (4 x 38mm pistons) accepts 295mm rotor maximum. I would like to run 343 or a min of 330mm.

Now the 7600 series of caliper (used in the Ap Formula kits and the like) has virtually the same dimensions/pad number etc as the 5000+ and also suggests that 295mm is the biggest rotor it can accept. If this is the case how are people running larger rotors. Is it another part number being ordered or are they just running the larger disc.

I have printed out the technical drawings from the website and cant find anything to help me.

Could someone please shed some light on this before i order becausr i dont want to end up with calipers that can only run this smaller disc.

I have also put this question to AP but have no response as yet.

The links are as follows:

Feedback would be greatly appreciated. BTW i am going to run the 6 piston 5000+ caliper with 375 x 36mm rotor on the front with AP pedal box.

Thanks in advance

Not sure about part numbers etc but have a look at the AP rears on here:

330x24mm single piece rotors with drum.

I went with the alcon front and rears - pretty well balanced with the standard master cyl. The cp5555's are nice in being able to run the 36mm thick rotor, but I dont think I will ever need it!
