5 Stud Conversion On An Awd Ceffy

[Lum]

Thinking of going 5 stud so that I don't have to drill brake discs any more. The parts thread says to use S14 hubs but that isn't going to work for my car as it's AWD.

Anyone know what parts I need to collect instead? I'm guessing R32 GTR or R33 but I don't know enough to be certain.

R32 gts4 or gtr for awd mate. In the parts thread

[Cupcake]

yes ^^

[Lum]

Aha! found it listed as "cradle". I have no idea what that even means. Is there another name that one of those is known as?

[Dan_J]

cradle is another word for subframe, it was ment to mean full subframe diff, hubs etc

what u need is front gts4/gtr hubs and rear hubs with the lower control arm as the gtst/s13 rear control arms have a small ball joint mount( doesn't have the extra coupler on the ball joint mount that the gtr has)

^^ Eh?

Wheel HUBS can be taken off the knuckle assembly and bolted straight onto current knuckle assemblies....

Balljoint is only relevant if you cbf unbolting the hub from the knuckle / too weak to unbolt hub from knuckle (like dudes who do dodgey-as-f**k S14 front 5 stud conversions) :P

So all I need is a set of R32 GTS4/GTR hubs, and a set of wheels of course. Awesome. (I'm thinking stock R32 GTR alloys)

What about R33 or R34 ones? Will they fit?

And thanks, I know what a subframe is, never heard it called a cradle before!

[Nic_A31]

Hubs, wheels, rotors (you already got), and calipers to suit (assuming you got stock calipers?)

Take the lot off an R32 GTST, you got 280mm front rotors, and 297mm rear rotors.

If you go R33 GTST, you got 296mm front rotors, 297mm rear.

If you change calipers, let me know, I took photo's of how to fit the ceffy brake lines to Skyline calipers properly (ie not shortening banjo bolts n shit....also a dodgey practice the S14 5 stud upgrade boys like to do....death wish if you ask me) I'll patch them through to ya.

And yes, R33 and R34 wheels will also fit.

Check out the build thread on my white Cefiro, that has R33 GTR rims, that gives you an idea on wheel fitment.

17 x 9 (+30 offset), the rears are fine but touch the guards sometimes, the fronts are very close to the coilovers (about 5mm) and close to the guards, but usually fine, no rubbing, scraping, etc.

R32 GTST (16 x 7) will fit fine, and sit inwards of the guards

R32 GTR (16 x 8) will fit a little bit better.

What's your theory on cut down banjo bolts being a death wish?

Good info otherwise, be good to see a 4wd ceffy getting round, now that's a rare car!

[Lum]

I already have R33 GTSt discs/pads/callipers. My main motivation for going 5 stud is so that I don't have to get the discs drilled any more! Not sure how he did the conversion, but I know it involved replacing the hoses with braided ones from a local company that makes hoses specifically for fitting Skyline brakes to S13s, so I'd assume no cutting of banjo bolts was needed.

The problem I have is the guy I use, a local Silvia & Skyline specialist, has a nice rig he uses specifically for accurately drilling 5 stud discs down to 4 stud but he recently took on a contract with a local race team that runs SR20 MX-5s, so now he has no time for us normal customers. I need to be able to just drive into my local tyre+exhaust place staffed by 17yr old monkeys and ask for brakes from a 1995 Skyline GTSt

Also, I was asking if R33 and R34 hubs would fit, not wheels!

Are R32 GTSt hubs also 5 stud then? I thought they were 4 stud? That would make things easier as there's loads of GTSts being driven around by idiots in my local area, so I can just wait for winter when half of them will get wrapped around lamp posts and then broken for parts!

And don't worry my 4WD Ceffy does get around. It's actually parked outside my workplace right now, and it's at a car show the weekend after next. If I quit my current job it will be my daily driver again too!

[Nic_A31]

Oh, my bad.

Yes, R33 and 34 hubs will fit.

Ive got R34 hubs on the rear on mine. Obviously though, you're waiting for a GTS4 to be written off if you want 5 stud on the front as well.

If you've already got brake lines made, then you're all good to go!

R32 and R33 non turbo's were 4 stud (RB20E and RB20DE) with shithouse single piston brakes all round. Infact R34s did as well, but they were 5 stud.

[Lum]

Obviously though, you're waiting for a GTS4 to be written off if you want 5 stud on the front as well.

Can't I use GTR ones?

[Nic_A31]

YEs and no.

REAR hubs on GTR are different in that they have a different number of splines, to accomodate the stronger GTR axles, GTR axles use a 6 bolt flange (6x1, not 3x2)

You could use GTR diff, axles and hubs, then you have stronger axles at the rear.

As for the fronts, not sure...I'd assume the fronts follow a similar fashion....

[Lum]

Ugh, so it has to be GTS4 fronts, and either GTS4 or GTS-T rears.

That sucks

I take it I can't put GTS-T rear hubs on the front?

Edit: Is the GTR front diff open like the Ceffy's or some kind of LSD.. Will be easier to justify swapping the front diff if I get an LSD too

[Nic_A31]

Dunno man, like I said, with the fronts I don't know if the GTR differs to the GTS4.

Put it this way, if it's a direct fit, sweet, if it's not a direct fit, then it's better/stronger, so might as well go it anyway, it just means you'd need to buy shafts as well.

Win Win, right?

[Lum]

Well the weak spot in my system is the auto tranny no there's no point in uprating the diff really, especially for one from a written off Skyline that's likely seen more miles and a lot more abuse. My Ceffy came with 28,000 km on the clock and even now is only up to 57,000 km

But I really want a front LSD after an embarrassing situation the winter before last where I got stuck in the snow with 3 wheels spinning.

I've been told on another forum that R33 and R34 GTR have front LSD, so if those will go on my Ceffy, I'm sorted
