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!

      Stock rb25det neo questions

      By GTSBoy · Posted

      While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.

      Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.

      I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.

      @Dose Pipe Sutututu I read your replies RE: R35 GTR MAFs, any ideal spots to put on? Obviously will need the adapter plate. Will be having a cross over intercooler fitted shortly, would putting it a bit before the TB be okay?
