Brake Upgrade - XT130/RT132 Strut with Nissan Alloy Caliper - Research Stage

[The Real Roadrunner]

The R32 discs has a total height of 54mm... If you were to use the 46mm high Vlovo disc, do you think this would solve the issue being that the disc, and therefore the caliper, would be sitting 8mm further out?

Also, would you be intrested in selling this bracket, how much, and which disc and caliper is it to suit? (eg. R32 GTS-T disc and caliper, or R32 GTR disc and caliper)

One of the biggest reasons I want to go roughly a 280mm disc, is the fact I've got 15" Simmons, and don't want to change them for this upgrade...

i actually machined 8mm off the back of the hub to suit so it wont change.
im getting the brackets made out of a single 50mm thick billet and once i recieve the bill for them ill let you know what there worth.
the reason i used the r32 gtst stuff is so if the customer went out and bought 17' rims later on i could then fit brembos off a 33/34 GTR and not have to change a thing, ie machine new discs the same but the caliper will bolt straight on, fit lines and the job is done.

So what is the final setup you are using? And are you still talking about xt130 struts?

Disc: r33gtst ground down 8mm
caliper: r32gtst with bracket to fit

So this would end up with 5 X114.3mm PCD, the larger R33 disks, 4 pot calipers and fit under 15's.

If this is the case, then I would like to grab a bracket as well as I have to get this all upgraded prior to Aug 25th. (and I am pretty slow )

Linden, if you machined 8mm off the back of the hub, then wouldn't this make the disc 8mm closer to the strut?

was thinking the same thing.

Please correct me if I'm wrong!

From what I can figure, machining 8mm off the back of the hub would sit the disc 8mm further inwards, where as having a disc that 8mm less in height would put the disc 8mm further outwards... Which I can only assume may help the caliper clear the strut ears...

So from that I have produced the following...

1. R32 GTS-T disc (54mm total height) - sitting on standard hub
2. R32 GTS-T disc (54mm total height) - sitting on hub that has been machined down 8mm
3. Volvo S40/V40 disc (46mm total height) - sitting on standard hub

2 is incorrect. If the disc is mounted to the back of the hub, maching 8mm off the MOUNTING FACE for the disc will move the disc outwards 8mm. Ipresume it is rear mounted as if front mounted it would have no impact. Remember, the bearings/hub would stay in the same place and only disc mounting face changes.

Dingggggg... Dinggggg... Dingggg dinggg dingg ding...

That would be the sound of the penny dropping in my head...

What you're saying would make sense, and would make what Linden said work also...

Thanks!

I thought the XT130/RT132 discs mounted on the front of the hub though, but I'm guessing not...

Linden,

If I was to machine 5-8mm of the mounting face (rear) of the hub and use the Volvo S40/V40 disc, do you think this would allow the caliper to clear the strut ears?

[chris davey]

Can't remember the stock one but my HQ setup on xt130 mounts to the back of the hub AFAIk.

Me going to take some photos and measurements tonight of the stuff I have done so far. I hit the brick wall, but hopefully will give others some ideas on how to/not to progress.

You guys are way more persistant than me

I'll just wait till someone smarter than me comes up with a solution

xt is rear over hub not over.

the more you machine off or lower the hat hight the more the calipers overhang th hub.
if your using 15" simmons on it only 280mm will fit, and you must use a 23 strut
if you go with 298mm discs i can do a bracket for these and they will fit in some 15"rims
ill get nath to bring a camera down and take some shots for you guys to see what ive done.

Which would make it near impossible to fit wheels on without the back of the rim hitting the caliper... Bugger!

Makes sense though... Thanks for your brain on this, it's much appreciated...
