It's a simple idea that I've searched for many times.

Simply post;

Car: eg. 32GTR

Brakes: eg. 355mm x 32mm 6 pot alcon bbk

Wheels: 18x9 + 20 BBS LM

Photos: eg. photo's of brake clearance

** Please not the above is an example only, the car isn't a 32 GTR and I can't confirm the size of the kit / wheel.

The idea is to collect in one place a list of what wheels fit what brake kits to help members such as myself looking for the largest brake kit that they can fit under a certain wheel.

If you have a big brake kit or run smaller then standard wheels (say 15" on a 32 GTR with OEM brakes) please contribute and help to make this thread a success.

This will hopefully clear up any confusion about what will fit and what won't, it will also save people buying brakes that don't fit under there desired wheels.

It's also a chance to be a brake whore.

Allow me to be the first to post some brake porn.

Car: 32GTR

Brakes: 375mm x 36mm alcon rotors with 6 pot alcon billet monobloc daytona lemans prototype calipers (custom hats and brackets)

Wheels: 17x9.5 + 12 TE37

I have only trial fitted these so far, as i am awaiting a few bits and pieces to refurb the calipers.

Have plenty of spoke clearance.

Have about 5mm radial clearance between the caliper bolt and the inner diameter of the rim, however the bolt has a 5mm spacer at the moment as it is too long, so i will be machining the bolt thread down 5mm so that the bolt head is then recessed into the caliper, which will give me even more clearance.

Got 4 pots on 343mm x 32mm rotors to go on the rear. Plenty of room for those.

It is a massive brake under 17s. I'm personally having a hard time believing he didn't mean 18s.

No I can gurantee they are 17s as I just put a fresh set of Nitto NT01s on them 255/40/17

I do what I can lol.

But dont forget that my hats and brackets were custom made so will not suit everyone.

Lets see what some off the shelf kits are like.

Those Alcon calipers must have precious little extra radial dimension outboard of the rotor. I mean the rotors are 375mm already. 17" rims are only ~430mm out at the very edge of the rim. You'd expect the middle of the wheel to be at least an inch inboard of that. 430 - 50 is already down to 280mm. I still can't see how it all fits. The last photo in your post is a rear wheel, yes?

No, it is a pic of the front wheel and rotor.

If you have a look at the first pic you will see how the caliper sits right down on the rotor, and the rotor itself is almost flush with the outermost part of the caliper. They are designed that way as to maximize the size of the rotor in the smallest possible rim.

Being a TE37, they have one of the largest inner diameters per inch compared to others, being that they are forged one piece. And yes they are ~430mm diameter at the very edge and then reduce ~20mm each side. So 430-40=390mm inner diameter which leaves 15mm gap total 15/2=7.5mm radial clearance on each side, which is what i roughly have.

Trust me, if it didnt fit properly, i wouldnt put them on unless i used a bigger rim, like an 18".

In all honesty I don't know why this didn't take off.  It's got all the ingredients for a great thread! 


I stumbled across this while looking for info on what 18"SSR Disk face (HP/MD/NR/SL) is needed to fit over my WGNC34 260RS with OEM (R33) calipers and 355mm rotors.  I'll contribute to this thread when I've figured that out and decide on wheels! 
I'm looking at Minervas in 18" or Formula Mesh, also in 18".

Meanwhile... any chance any has info on this? 

Cheers!

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
