4 Stud To 5 Stud

[CrankyGTS11]

I have posted this in the brakin section but i thought it might actually get a response in here??

Now i have heard that this a a relativly easy exercise??

I have a SVD GTS which apparently already has the same front struts as the R32? and therfore the new callipers will bolt straight onto the front of my car..?

But wat is the go with the rear???

I am mainly doin this as there is little choice of wheels for the 4 stud cars.. unless anyone can point me in the right direction there also.. but 4 spot fronts would be nice.. mmmmmm

Thanks for any help guys

GTS struts are not the same as R32, as R31's have Macpherson strut fronts (Like S13) and R32 have Double wishbone.

Converting the Fronts to 5 stud is easy.

Press a S14 or R33 balljoint into the R31 arm, Use S14 hub/Knuckle/Stub Axles, and use R32 calipers and rotors.

Remove olive from r32 Caliper and use S13 banjo bolts so you can use R31 brake lines.

Rears are a little more complicated if you want to do it properly.

You can get a 4 to 5 stud hub adapter/spacer made, but you'd need to have some high-ish offset wheels to use them, as the narrowest ones Ive seen are like 30 mm or something.

or EA falcon axles from a wrecker, send to a diff specialist.

They need to be shortened by about an inch, and have 5 - 10mm machined off the bearing platform (Not Sure if thats the exact term for it), Then resplined and heat treated, then redrill stock rotors to 5 stud.

Was quoted $500 all up for this inc. installation.

Decided just to get 4 stud wheels that fit instead, Which is still my recommended option over a 5 stud conversion.

I had wheels custom made by ROH here in adelaide, in 18 x 9 +/- 0 and 18 x 10 + 5 (I have very large all metal flared guards on the car, and my sideskirts are like 2 inches off the floor)

Seeing as you have a GTS2 as well, Id suggest getting good offset 4 stud wheels so you dont have something thats very hard to reverse, as your car has good resale value, and is getting kinda rare.

You can still do the 4 pot brake upgrade too I believe, GTS2's have import struts, which have the 100mm bolt spacing required for R32 calipers. Just remove the olive and use an S13 banjo bolt.

Thanks for that mate..

I will jsut look for some wheels first, as like u said i do want it easy to put back to std. but i will definatly be chuckin a set of r32 calipers at it..

I would really like to run 19's on it,.., but buggered if i can find any decent ones..

as you might be able to tell i have already done this to my GTS2,

i used HSD HR S-13 coilovers, S-13 hubs, brought a set of S-13 5-stud hubs from "justjap", i also used s-13 tie rod ends with adaptors i got from the r31 forum (i used s-13 lower control arms which are longer then the r31 arms so the r31 tie rod ends were too short to safely use) i went to the r32 4 pot callipars & rotors.

the rears i had 2" adaptor plates made to mount the coilovers, got the r31 rear axles filled and re-drilled to 5-stud by an engineering place here on the gold coast $300 with brand new longer studs installed and the rotors re-drilled to 5-stud.

Running 19's on your GTS is illegal as well. You can only run 18's.

Why did you buy a GTS if you want to mod a car?

Everyone on here knows I am the ultimate pain in the arse when it comes to modding one of these. Unless yours is a heap of shit, or very unoriginal, leave it alone.

I do like RSX84's car above, but that is under sufferance.

It's hard to find the right offset in a 4x114.3 stud pattern, there is lots of info on them here - www.r31skylineclub.com. I know you have been there, and the R31 forum has much more info for your 31 than here. (Not hanging shit on this one though). Horses for courses. As I said in one of your other threads, contact me on [email protected] if you would like any decent info, genuine parts or just general help.

[R31 drift pig]

Now that Cazz is on your case, I wouldnt be putting 19's on it LOL......

Get some white 16's/17's in good offsets and widths and Keep the GTS-2 wheels aside. Your car is worth a lot more the less it's modded. Unless someones been at it before you, Buy a S3 Exec or GX if you want to mod it. As you have 100mm caliper spacing, Get a pair of R32 calipersa and chuck em on, but keep the stock gear.

I couldnt do what Ive done to mine to a GTS2....

[rsx84]

my ideas behind modding mine was more along the lines of bolt on parts, all the work i have done is reversible. all parts removed are stored as i have no need to sell them. i like the interior and love the colour, kit is perfect...

[R31 drift pig]

Unfortunaley, the mods done to my 31 are pretty much irreversible.

Guard flares, cage, engine swap, paintwork etc.

IE. couldnt have done that to a genuine GTS2.

[CrankyGTS11]

My plans are to make it all reversable.. thats why im now trying to find 4 stud wheels.. and 19's are legal in tas..... as long as my tyres dont go 25mm above std hight.... but i will prolly go 18's so that i have a bit more tyre,,,,

im only interested in putting wheels and a bit better brakes on it... as much as i love the car id like it to stop better!

[rsx84]

i'll be doing an engine swap soon as its still bolt on but i'd have to trim around the head light to put in the cooler piping in the way i want it, thats what has held up the swap so far umming and arrhing...

Then switch to R32 front calipers with S13 banjo bolts, and Id go looking for some 17's actually, lots more available in 4 stud in good widths and offsets.

Kool so with 32 calipers i dont need to change my disc size??

I'll keep an eye out for wheels for sure. i'll fine sumthing
