Hey guys,
Just wondering at what horsepower range would you say it be a good idea to change the stock 1990 240sx brakes into the 300zx or skyline ones?
Or is the 4 disc stock brakes good on the s13?
I am planing 210 to 250 whp
Thanks
stock brakes should be fine for a basic turbo setup…
Upgrading to stainless lines, aggressive pads, new rotors, and good fluid will usually make stock 240 brakes “good enough”.
Also kinda depends on what wheels you are running too. Big heavy 18’s, I always feel better with z32/r32 brakes.
lol@stock brakes being fine for a basic turbo setup. I could overheat my z32 brakes with HP+ pads with my KA 
Stock brakes I would fade in traffic ha ha ha… I would upgrade to some z32s they’re dirt cheap. And now a days there’s plenty more affordable wilwood setups cheaper than mine (smaller but even lighter = better braking). My setup is the AZC bigger front setup, i can’t fade it and love it Can stay on track all day long and not worry about braking issues.
Now if you’re drifting, you don’t need a lot of brakes, but on tight courses and such… you need brakes…
250whp is enough to kick some major ass on track in an s13.
i heard Ford Taurus brakes are really good.
on a real note, i have q45 brakes which are the same as j30. they are the cheapest upgrade you can get, and are bigger.
again.
lol you made a funny.
Stock brakes suck And yes a ford taurus’ brakes are better than a stock shitter 240 You mad?
22 and too old for this.

I’ll stick with my first bit of advice. Its always worked out well for me.
For KAs and 240s i reccomend going to 180sx (not silvia) brakes with hp+ and brembo blanks, fantastic and not too expensive. If you can afford it, i would go with z32 fronts and rears or jdms14 (28mm aluminum).
good point about 18’s and z32 brakes, that is my setup everything feels good
also depends on how you drive daily and whether you time attack and/or drift…
18s = heavier especially if some kind of cheap rims thus more unsprung weight = worse braking/handling/less compliant ride, etc…
Here’s some info for ya:

j30/q45 calipers are dirt cheap if you wana go with that. They also happen to generate more torque than z32 calipers but the z32 calipers have better feel due to more pistons.
I got fed up of hunting used parts/rebuilding and just decided to spend money on new parts hence my investment on a wilwood setup front and rear. Best decision I made. Two+ years of abuse on street and track, no fading, awesome braking, pads still look like new, rotors worn down but still plenty life to them although I’m confident I’ll be changing them next year and I might want to try to some pads that are a bit more linear but have initial bite (just personal desire for feel). The only thing I want to change is go to a true dual mbc /w a bias bar setup for better feel, I hate the sloppy power assisted feel and floppy stock pedals. That’s just me… I am very very picky on everything…
Now a days there’s a lot of cheaper brand new wilwood options though… the money is in the hats (if you so chose to go with 2 piece rotors) and mounts… on the other hand the calipers, rotors, pads are readily available. The whole setup is bigger, thicker, etc… but lighter than the z32 setup. I weighed it. It’s drastic… Keep in mind lol… the z32 front rotors are smaller than the rear a bit.
Do more reading other than ‘stock brakes are good enough’ because joe schmoe told you so.

… There’s a reason shit costs less and some shit costs more money. Plain and simple. Personally I have no idea how people can endure driving the shitty stock brakes??.. Drifting does not require brakes like spiritied driving/lots of cornering/etc… plus having to go off track to cool down is too gay for me. I like to enjoy myself all day long with no stopping (lol). Hate on me for saying all this all you want. I mean I can’t imagine going back to a stock anything on any 240 the car is just too damn sloppy/boaty/unexciting and slow… and the brakes are one thing that kill it for me when I think I’m driving a sports car… just as important as good grip and handling to really be able to enjoy myself… power meh no care so much.
Look at what you get for the money you invest when buying used parts or patching up the ‘stock brakes’ or even used z32 brakes or whatever. Some ‘good’ pads, rotors, lines, etc… and you’re looking at minimal improvement… if any and you’ll be spending again and dealing with shitty old stuff. Go to z32 setup again you’ll be spending money here n there, etc… and again shitty old used stuff, possibly rebuilding, etc… it becomes a money pit down the line and you soon realize that maybe I should have been smarter and spent a little more from the get go and profited from it in the long run rather than spending all the time on shitty stuff and knowing you’ll always want more down the line for sure.
Remember also the more aggressive the pads, the more heat… so sure you can stop faster (given that you got good tires/grip), but as you induce that heat, the more you’ll fade with crappier cooling capacity of smaller rotors, so all I’m saying is, if you look at it out of the box, spend little now and alot more over time or spend a little more now and enjoy yourself alot longer throughout through.
Meh… my 2 cents hate me for it all you want.
Unless your tracking the car and heavy on the brakes just go with something simple like aggressive pads/rotors, next step up would be 180sx brakes etc. Just the pads alone make a world of a difference but will eat your rotor alive. Stainless lines make the feel of the brakes amazing! If your doing circuit racing go all out on the brakes because they will be under a lot of stress.
One theory to keep in mind, if you cant lock up your wheels under hard braking your brakes could be better improved. If you can lock up your wheels your tire/wheel/suspension and many other variables could be better.
Alright thanks for the advice guys.
I don really go to tracks and stuff but in the streets I’m driving and a dumb person presses there brakes sooo hard for no reason and it makes me push mine hard which causes the skidding. I know it happens in all cars but just how the skidding happens so fast makes me worry about the brakes.
Does changing to stainless lines, aggressive pads, and rotors really change the braking system that much? Will i defiantly be able to feel it when braking?

And how fast does the aggressive pads kill the rotors if your a daily driver with ummmmm once in a while racing habits lol
Going to more aggressive pads will generate more heat, be harsher on your rotors therefore your rotors will not last as long. It’s physics, you gotta give or take, just like the money part, more money vs less money invested lool. Sucks how life is but that’s just the reality of it.
I tried to fiddle with the stock brakes and z32 brakes but what I ended up with was too much brake fade going to more aggressive pads, I GUESS one thing I could have done is ducting at the time to help with cooling but meh. thats one smart thing to do.
Changing the lines improves feel because the stock rubber crap is probably rotten to hell and ‘breathes’ while the ss lines are solid/new. More aggressive pads will obviously help stop better and have better feel than some old oem junk… so that’s for sure… but again will kill rotors and brake fade will be possible with consequent braking. It’s always a give or take game. You win on one end or you lose on another. Bigger rotors = better cooling, better torque, but heavier unsprung weight. More aggressive pads = better torque, better feel, but potentially cooling/fade issues, rotors murder, etc… as you can see always a give or take.
What dev said is very true about if you’re locking up or not, you could get the most fanciest porsche/lambo 8 pot calipers with 16" rotors lol… but if you don’t have the tires and grip for it, its useless and will lock up on you. Tires/grip is very important to stop faster… so good tires will be your best investment from every aspect of your car.
Oh and one more thing, regardless of what you end up going with, another thing (you will have to do anyways) is change brake fluid, while you’re at it get something good like ATE brake fluid, its cheap and proven.
stock brakes = crap…
Z32’s are a worthwhile investment. = no warped rotors, pads last seemingly forever (years)…
(180 brakes) + (stainless lines) + (EBC3GD) + (Hawk hp+/Yellowstuffs) + (motul)= feels really nice
double post
for about 750$ you can have a two piece rotor, wilwood calipers, pads, brackets, lines for the front. In the rear could stay stock. A world of difference and the setup I am mentioning has super cheap rotors and pad replacements… mine is larger and more expensive. Check NRR, Def made one, he made a bunch of stuff for me, smart guy.
Basically what I’m saying is for the price of a used z32 setup, rebuild kit, pads, rotors, etc… for a tiny bit more you get something brand spanking new SUPER lightweight, etc… DO IT lol

12.2" Rotor, Wilwood Forged Superlite kit - S13/S14/Z32
Larger rotors, larger pads, superior calipers, cheap pads, cheap rotors, 2 piece rotors, ss lines,
He’s very honest, a mechanical engineer and made me a bunch of stuff already previously. I got the AZC wilwood 6 pot f, and 4 pot r setup but meh… this is better in some ways.
It’s just stupid to be getting old s13 or z32 brakes anymore… z32 setups are so 1999 lol.
What is the best place in GTA to buy pads and rotors for your 12.2" Rotor Wilwood kit?
I don’t buy locally i buy everything in the states. That being said I think JRP carries wilwood stuff and I don’t have a 12.2" setup that’s my rear, my front is 13"
