Ive heard of a few guys saying that the addition of a BBK up front is eating up their rear calipers/rotors due to brake bias. Is this a major issue for most people and if so is there a way to alleviate it? thanks guys,

Not with my original 12.2" Fastbrakes or my modified 13" Fastbrakes;
Nor do I have that problem with my AP Racing Kit either...

All those kits have a greater piston surface area than stock (3.14 in/sq) at least on 4th Gen. That coupled to a greater torque arm radius of the larger rotors...

 

Ok cool, I just got some Z32 aluminum 4 piston 30mm calipers and 13" RTP slotted rotors so hopefully they'll work well. Ive heard good things about the setup but just trying to get several opinions, thanks!

I haven't had that problem.

I think that is only happening to some of the 6th gen guys who have the electronic brake proportioning system or whatever it's called....the sensor "reads" the brake bias wrong with a BBK for some reason, apparently.

 

No, it's because the car is lowered. Kam said that when he had Progress springs all around the rear brakes would lite up a lot, but when he put the OEM springs in the rear and did the same test, both front/rear lit up evenly.

The sensors think that there is added weight in the rear (as in passengers or cargo) and therefore it applies more braking for the rear.

i'm new to the abbreviation 'RTP'. what does that mean?

 

Good question, main point, it's just another company that makes rotors.

 

ah, thanks

 

Exactly, i couldnt fakin believe it my self till I tried the test. Frig even the Techs at Nissan Shop are wondering how the hell that EBD (electronic brake distribution) system works. I read the FSM and there is a proportioning valve but I cannot figure out where exactly it is and how to modify it.

Where did you get that setup from??

 

pieced it together from the 4th gen classifieds

 

I'm in the process of trying to find a setup now but. I just want to make sure it is quality. Is rotora and power slot any good???
