as far as discs on the back, have a look at my site

for a couple of options

but with the stock diff you are pretty much stuck with what you have

you havent got the borg warner iff in your 120y i am pressuming?

BULLSHIET to both peddler and nutcase!!!!!!!!!!!

peddler try driving without back brakes, they do heaps, my backs wernt working for a couple of days and the ####in fronts lock up so much i couldnt stop for anything in a hurry (if the lights changed i had to just keep going through), ended up hitting someone elses car on day 3

and nutcase you make the conversion sound easy but it is a BIG job your talking about, you have to change discs, spring cups, machine calipers, prob make up castor rods (not sure bout steering arms), find springs that sit the right height.

i have pics of hi-lux 4 spots on my stanza struts and with vented discs, i know what is involved and have also considered using 240K struts and have heard whats involved in fitting these, it definately is not a case of just switching over like you seem to imply

Dude..... I know that the disc brake set up may look good and pending how good you are with spanna not to hard to convert but honestly weather it is track work or whatever there really isnt a lot of difference from drum to disc on the rear of a small car.

Reason being is that under braking either hard or soft, you transfer the majority of the weight to the front of the car (pivoting) meaning that your rear brakes do little. Unless you are going to have adjustable brake bias which most track cars will have you are better of spending your money on some go fast bits or for that point better front rotors or calipers maybe...... only a thought i hope it helps

Cheers

If you are just wanting better brakes Wilwood makes a caliper called a Dyna-light these come in 2 and 4 pistion. US hot rodders use them because the will fit over 1/2 thick non-vented rotors price is $125 US.You would have to fab a carrier but that is easy as you will just need a flat plate.

nutcase, have you done the Z car strut swap?

They have a wider bolt spacing at the base than other Datsun struts, so you'll have to get the Z steering arm as well as a minimum.

What lower control arm/ball joint did you use?

Did the 1200 outer tie-rod end fit the Z steering arm?

Thank you Nutcase, so I can use any Datsun Z struts and Hilux Calipers...thats for the front end, any idea for a rear disc swap?...I'll use the Z's and Hilux on my 120Y Wish me Luck!!!

go Z the struts are short and have big disks then install a set of toyota hilux calipers they come on the 77-79 4x4 hilux here in the states
this is the setup I am doing on my 120y

As every one is talking about brakes here, i want to make a Question...I have a 79' 120y(It is my first Datsun) and I want to improve the brake system (MC, front & rear, piping, etc) what kind of swap shouth I Do?... is there an easy way to put rear disc brakes?...Thanks!!!
DATSUN RULES!!!

Datsik you are dead right the big block late RWD Sunnys having the same brakes as the 180Bs etc. I have a pair on my GX. I am a fan of them for conversions cause they retain the correct king pin angle. The Stanza conversion screws things up a little. If you want an easy stealthy set up, cut down the Sunny tubes and slide the smaller diameter 1200 strut and spring seat inside the Sunny strut, it's a sliding fit and weld around the spring seat to give it a factory appearance.You can lower your car and Mr Plod cant see how !! The down side is you are stuck with the small internal dimensioned 1200 strut for shock inserts but Corolla and VW Golf ones work well.

stanza brakes fit inside 13"

while your getting the castor rods from a 120y you can grab the swaybar too ya see, 120ys are good for two things

when ya get the struts ya just bolt the 120y castors too them and they just think they are off the stanza, so no extra cost, slippery but hey ya get that
