Summernats was pretty massive this year and there's a bunch of videos posted on youtube of all the action. An SR20 1200 wagon caught my eye in the horsepower heroes with over 1000hp. Not my car and not my video, but link below for anyone interested.

Hey mate,
I'm running 14 inch R31 skyline steel rims (from memory they're 14 x 5.5 inch with a +30 offset). As mentioned by others, the front lower corner of the front guards needs to be massaged and rolling the lip of the front portion of the guard is also beneficial.
Been ages since it was actually done to my ute, so a little hazy on what we did.
No fitment issues on the back though (again as others have said).

I'd run and grab measurements for you, but i'm in Western Australia and my ute is in Queensland.

Not sure where you're at with your build, but if you're planning a brake upgrade in the future make sure your wheels will fit your planned discs/calipers.
Cheers

I think the main benefits are that S13 parts are readily available and you get the S13 disk/rotor over hub rather than having to go down the route of customising brake parts to fit.

I'm not familiar with your build, What struts are you running currently and what are you looking to gain by going S13?

Yes it is, same part DBA number.

The rotor hat/adapter will look something like this (see image) i think. Maybe out of aluminium, but depends on the size of it. I'm still working out measurements. May do a demo up in 3D.

I can't find any other option for vented brakes under 14's without increasing track. I hope the stuffing around is worth it. It'll be a bigger (if only slightly) disc, vented and with a bigger caliper.Has to be worth it.... right?

Where is the best place to look for brake pad options with a given caliper?

Trying to go vented, under 14's. So the 280mm vented jobs won't fit.
If i use this (see image) BT50 rotor with no modifications and use a custom rotor hat I can fit it behind the hub. I don't like the idea of machining rotors, too much stuffing around when i need new ones again.

I thought the s13 stuff only suit the 1200 struts, I'm running stanza with coilovers. Am I right or am I wrong? I'm trying to avoid the extra track increase of putting rotor over hub as my wheels are close enough to the guards now. I know it's not much, but the extra few mm of rotor would push it a little too far I think.

I did forget about the handbrake move. From memory I don't think it was all that involved though, don't remember shortening mine.
I went with a modified stock tunnel, but if i had my time again i would cut it all out and fab up a bigger one for ease of access when things like the clutch need doing. If you do go down that path you need to make sure that your engineer will sign off on what you do. So tell them your plan before you attack.
Good luck with it mate.

Slow progress on this little project. (I'm in Perth and car is in Brisbane )
I'd appreciate input on the option that I'm considering at the moment. I couldn't find a disc that would be a direct bolt-on for the stanza strut that would fit under 14's so i've come to a new solution that may be just as good. A mazda BT-50 2wd has disc's that are 255.5mm diameter and does not have a "hat" I.E. they're are only as high as the thickness of the disc (24mm). So i'm thinking of using them and fabricating a custom rotor hat to attach behind the hub, same as the standard solid disc. Is this the right way to go, or am I reinventing the wheel for no reason?
Caliper options are the factory BT-50 single pistons, but for pad options i'm leaning towards the late model Subaru stuff that also suit 24mm but twin piston.
The aim is to get vented discs, no track increase, fit under 14's and have parts availability in years to come... without breaking the bank of course.

As always, thanks for any feedback

The CA18 manual trans does put the stick back a fair way, but to remedy that it's a simple flip of the stick. Remove gearstick from trans and turn 180 degrees. Position is comfortable and functional.
