R33 gtst big brake upgrade

I found this Endless Braking kit for R33GTR but doesn’t show as fitting for a GTST. 
Wondering if there is a difference in mounting and what I would need to modify to fit, if anything. 
And if anybody has done similar 6pot or relative size brakes on gtst and what was needed to make that happen. 
 

bonus: If you also know the offset needed to run these with BBS LM’s(18x10 rear and 18x8 front)

If it bolts up to a R33 GT-R, it will bolt up to a GTS-t.

You'll need to trim the lip on the rear dust shields all round, some people bend it back. I found it's much easier to flap disc it off, then hit it with some black paint.

Okay great! That’s what I thought! 
 

I saw that the ‘03 350Z brembo are the same size as the GTR brembos also, difference being you just have to drill from 12M to 14M for the brackets but I think that’s a pretty easy mod considering and would be worth it for this as well if need be. 
 

do you happen to know the dimensions of GTR brembo, cause if the endless are within a few mm of those I won’t have to worry quite so hard about the wheel offsets being an issue.

Yes they are, however you need to also run the 350Z disc (albeit the same thickness and diameter) as the hat offset is different to the GT-R rotor.

And in terms of caliper dimensions, no idea :D 

I know that stock R33 GT-R wheels fit over a GTS-t with 350Z Brembo calipers.

Awesome thank you!

You need to know/figure out the caliper clearance of those BBS wheels, as in the space behind the spokes. Offset doesn't really matter. That screenshot looks like it's from Nengun heh.

Ahhh right right (I’m obviously not a wheel guy)… so yeah I wasn’t thinking about that… so like the curvature of the actual spoked area on the hub is what I need to clear, and the distance from the rear side of the wheel hub, to the hub’s mounting plate area that goes against the brake rotor is going to be the distance needed to clear. Am I correct in that? 
and as far as distance from inner wheel diameter, I’ve seen 18” wheels with endless brakes so that circumference should clear just fine depending on the rotor size to accompany. 
 

okay so let’s say the back of the bbs to the rotor is shallow by 5mm or something, could I just get a hub-centric spacer of like 8-10mm to make up the difference and it will work?  
 

sorry for the noob-ness ^_^

my first skyline, and my Supra and other cars in the past the wheel guy just gave me what I needed and I didn’t have any special brake situations or anything to worry about

Yes. If there was a 5mm interference you would need to space thee wheel out by that 5mm plus as many extra mm as you feel comfortable. I'd not really want to run <5mm clearance, because even though all that stuff looks stiff, there is some deflection. If you only leave a 2mm gap, you might learn how much deflection is possible.

Not sure about this kit but I know other brake kits have had a template that you were able to print out to check it against your wheels to see if you have the correct clearance 

18” wheels will clear a lot of brakes but offset and spoke design also play a huge part

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
