300zx vs r32 brake setup

[Emperor_Tha]

which calipers are better and why? F+R? aluminum or cast iron one?this is for a s13 with no abs.

i heard stories that the 300zx f+r lock up at times with no abs. is that true. is there a way i can advoid that.

is it okay if i upgrade the master cylinder for now to a 300zx on stock caliper.

[yokota180sx]

dudethey lock up if you cant drive

all my cars have had R32 GTR front and rear, with stock master cylinders

and i didnt lock up and i tracked one of the cars

[RideNslidE]

iv'e heard its ok to just change fronts over to 300zx but the braking split point is different and there is a good possibility of you locking the rears under heavy braking. just my suggestion if i was to do it id get all 300z stuff for ease of parts switch to five lug do up all 4 brakes and change the m/c. you should have more than enouph stoping power. good luck

I fyou dont have firsthand experiencedont talk

[Emperor_Tha]

so the r32 f+r and stock m/c will be okay.....this is for more of a daily driving.....maybe track once a month or so

[austins240]

I have the r33 setup on my S13 non-abs with the stock MC. I have SS lines in the front. It works fine and for daily driving you won't notice anything out of the ordinary.

I did notice the proportioning was off and the pedal is softer but i'm sure it's because i'm pusing 12 pistons now VS the stock 4 lol

it'll be fine without the bigger MC, but i will be upgrading mine eventually.

you can obviously see i havent done this. all i was doing was offering my opinion in this situation which is what i would do. i belive retaning all of the brake componints from the stock application would be best but hey maybe you know better than i.

But I do, and you need a master cylinder that's proportional to the biasing. R32 GTR? More like R32 GTSt from some guy who couldn't get rid of his ride before PCSing back to CONUS.

lol

aren't the gte's still four lug? hell yeah!

what you know about that :P

[Chukidori]

Yeah first of all.....All non ABS brakes lock up at times, but only if your braking force exceeds available traction for those tires. To correct this you have to learn to modulate the brakes properly .Thats why they invented ABS which does it all for you a hundred times a second So instead of you having to control the brake, you just floor it and a computer controlled valve opens and closes to stop hydrolic pressure and keep the brakes a constant MAXIMUM level without locking the tires.

^_^ thats why in ABS cars the pedal vibrates when you brake hard.

well personally i just got my 300zx front calipers, rotors, and SS lines, but i just kept my 240 rears, but added some drilled and slotted rotors all around and SS lines, kept my MC and the thing has really good braking power. In my opinion, unless ur planning on tracking the car all the time, just keep ur stock MC, buying the new 1's are expensive.

aren't the gte's still four lug? hell yeah!

what you know about that :P

R32 GTSt are 5 lug, and the calipers you usually see for sale as R32/Z32 are usually from the GTSt, since to part out a GTSt is a cheaper affair than a GTR. Go figure. The ones you are thinking of are the 4 lug GTS, GXi.

[austins240]

i was at camp zama for a few years. i thought i remember a guy that we made fun of for buying a GTe or something. kept calling it a dishwasher. was a four door and i could have sworn he told us it had a 4-cyl but i saw badging that was gte IIRC.

regardless, it was the ugliest, slowest, and most boring skyline i saw my entire 4 years there.

the R32 GTSt's were everywhere. That's the first car i ever got to convert from AT to MT. learned a lot on that car. but some baller 18's, twin plate metalic clutch, 5-speed, exhaust and a diff on it and had some fun. that rear wheel steering was pretty trippy. car was a POS but fun to throw around.

hey dumbassIM in japanthey are GTR

[Emperor_Tha]

ok, i will get r32 f + r , should i get the 300zx m/c and a r32....i havnt seen one for sale, but the 300zx are new or reman.

[94_240sx]

There are several different versions of z32 MCs and what you want is 17/16 Nabco.

[RB20DETodd]

i have 30mm iorn calipers GAY i dont see why anyone would not run aluminum these weigh a ton

[AZhitman]

No need for a different MC, and in all actuality, if you're running proper tires, there's really no need for Z32 / R32 rears on an S-chassis unless you're one of the top Time Attack drivers on the circuit.

More than 75% of S-chassis braking is through the fronts, and even during track use the rears rarely reach optimal operating temps for real aggressive pads.

If you're locking up, you have a tire (and/or suspension) issue, not a brake bias issue, and ANY tire will lock up under the right circumstances.

Z32 fronts with quality tires, good pads and quality rotors are all 90% of s-chassis owners will ever need.

[austins240]

i see your point but in my case i have noticed that the rear brakes are taking more load than they should. I have taken apart the Z32 MC and noted it's design and spring/port sizes. I'll be doing the same with my stock MC if i can ever find a decent Z32 MC in operational order. I drive my S13 on a weekly/daily basis and have no issues with that. i have yet to track it though so we'll see.

if i initiate a burn out (testing my brake bias) it fails :P the rears are simply holding too well in comparison to the fronts. with only a front brake upgrade i would understand this working better.

the other reason i'm glad to run the rears, inner drum E-brake FTMFW.

and my S13 calipers in the rear were pretty nasty, leaking etc. i'm not a fan of floating calipers either but hey, my setup was free.99.
