If you are like me you are poor
Essentially what I wanted to do was get the most stopping power i could without swapping to the 5 lug and without changing out of my stock wheels. I do love the tear drops for some reason...
My brake upgrade consists of J30 calipers and 03 sentra SE-R rotors.
From the stock 10 inch rotor you go to a larger 11 inch rotor and the small one piston calipers are replaced by larger J30 two pistons (I'm sure the Z32 4 pistons will fit and bolt on the J30 lower bracket.) The main problem with the old way of swapping to J30 brakes was drilling the J30 rotors ( people do it) to the Four lug or swapping to the 5 lug hub. I didn't want to buy new wheels and the new hubs.

So what you need to do
-lube the j30 sliderpins if you get them from the ol' J-yard
-remove old calipers, pads, and rotors.
-remove the hub (30mm bolt) to get to the dust shield
-remove the dust shield
-pack the bearings and replace hub, they're probably going to need it
-Fit on your 4 lug sentra SE-R rotor (Basically a 4 lug j30 rotor)
-Bolt the J30 calipers on, same bolt holes as stock (19mm)
-place the pads in bla bla bla
-Bleed the brakes, replace the wheels, and go for a drive

You will be surprised. The calipers clear the wheel by one millimeter.
Ill have pictures up later if anybody wants them.
thanks

 

They are the same as Q45 calipers which I have on my car. Watch out for lock up. It happens easily with such a large front bias.

Are the rotors the ones used with the Brembos?

 

im just going to get drilled and slotted rotors with good brake pads and steel braided lines. the stock brakes work just fine they lock up just fine but they get brake fade whitch is not good. what i just stated above will help with not getting brake fade.
with out having to worry about them locking up so easy.

 

yeah the brembo ones will fit
They do lock up but if you find right before they lock up they slow the car so well.
I need bigger front tires now. atleast 225s

 

same rotors as late 90s G20 and Altima. The problem is that the rotors are 5mm too thin, cutting into the useful depth of the rotor/pad combo. Be aware of how low your brake petal is getting not how much pad you have left.

same thing i'm doing at the moment.

 

sticky?

 

^ better get some high temp or racing brake fluid while your at it. good pads like the porterfield R4's get hot when under a lot of braking. eventually it will boil the fluid and bubble up, you dont want that going into a braking zone at a race track... Oh shit! what happened to the brakes!

 

I think I'm going to do j30 rears too... just like Longfellow said the front bias hurts. After that the car is defiantly going to need a bigger master cylinder, maybe an adjustable prop valve too.

 

Im looking at the Z31 bracket mod. Theres a write up on F/A about it.

 

or you could just redrill the 5 lug rotors for 4 lug and be done with it. i had 98 q45 fronts on my 4 lug s13, but they required 16 inch wheels.
