Mmmm yes this is what I want. I actually already have the calipers and discs.
If you do a search you'll read all my findings...

I haven't read what others have written, but I DO know that it's not greatly difficult, I've looked into the process of adapting Skyline brakes onto various Toyota struts myself.

The hardest part I can see is getting the rotor to fit the hub. Then worry about mounting the caliper.

I have held a pair of these modified struts in my hot little hands. The rotor's and calipers are massive. Spoke to the owner who was selling them (I was just the shipping agent). Custom machined stub axles to fit the RA23 strut housings along with a custom billet polished patented alloy caliper mounting bracket to get between the standard strut 90mm caliper mounting bolt holes and the calipers themselves. Its only moneyt after all.
Cheers,
Mitch.

are the stub axles the same size as ra40 cause i run the skyline brakes on my ae86 which uses ra40 struts and the conversion is simple.

Turbo RA28,
1. Perhaps - but I lost his phone number and address and it has been at least 2 years since I saw this guy, so hope is gone now.
twinturbo86,
2. There is every chance that this is the case. He used R33 rotors and calipers so whatever spec's that stub axle is, custom made to fit RA23 struts.
Turbo RA28,
3. No, I was just sending the struts to a third party, no pic's came via me.
Cheers,
Mitch.

I would like to know if you have any pics of your brakes you could share with others

You'll need longer studs, you'll need to increase the centre size, and you'll need to space the calipers slightly from the caliper mounts on the strut, and use longer bolts. If you use S14 4 spots, you can use a (4 spot) R32 GTS (non turbo, 280mm, 4 stud) rotor, or if you use the 'bigger' nissan 4 potters, you'll need the R33 GTS25t rotor (300ish mm, 5 stud). If you use these, you'll either need to redrill the rotor, or start with new, undrilled rotors and drill them. I might be able to take some pics of what it all looks like sometime, if you'd REALLY like

Haha i'd Really like that!  thanks!
I have 280mm, 30mm, 5 stud discs from a 300zx. The calipers also came from the 300zx twin turbo. They are alloy and take the 30mm disc.
Maybe i'd be better off getting the S14 rotor though.

Just some information that i have stumbled across of late when researching a brake upgrade for my car is that, std 22 and 23series struts run smaller wheel bearings that a ra28, ra40 corona xt130 etc. The wheel bearings in these models measure 3/4 for the outer and 3/8 for the inner, exact same size as bearings as a vt 300mm disc, or anything else with thoses size. Being of a larger and more commonly found size bearing in these struts as apposed to 22 and 23 series struts a swap to these struts would be invaluable and probably save you time and money maching your original stub axel. All that need to be done then is machine your chosen the disc to 4 stud, or you can run the orignal stud patter of the disc as it should bolt on to the stub axel with no problems, all there is to do is get a bracket made to do your caliper conversion.

I looked into using skyline rotors a while ago and decided that machining the hub as much as required was just making a massive weak point in the whole package. You might aswell just use standard TA22 brakes because neither would be any more reliable than the other.

Perhaps... but then have a think about the size of the Nissan hubs
The bugger of using Commodore rotors is that it will screw up your offset a fair bit, plus the fact that you'll need to buy the rotor/hub cast as one unit (i.e. pre VR), as the later ones with a separate rotor don't have a removable hub... You CAN always smash an older style rotor to pieces and machine down the hub, but then you might as well use the ra60 (or whatever!) hub!
Also do the 23s use the smaller stub? Bugger, I spose!

The problem with the skyline rotors is you have to machine so much off the hub that the wheel studs are nearly protruding the out side edge  Most engineers wont accept this and I certainly wouldn't want this setup on my car.

Maybe using a 2 piece rotor is the way to go? Wouldn't require as much mods to the hub.

Just suppose that there is some1 who can use a one piece vt disc, just because a cast has been made and all need be done is have the holes drilled and studs placed in. Then you can use a one piece unit.
