Apart from Unique Autosports does anybody else make the brake caliper adapters to go from 296mm to 324mm rotors?

These are to use the stock GTST calipers with the larger GTR rotors (going to use the 2-piece ATTKD rotors I think).

If not I guess I'll just have to fork out the $350 for the adapters.

I recommend people ring a few machine shops and get some hourly rates from them. Unless you have a mate with the tools required who will do it for a case of beer, you will be in for a rude shock. $350 is pretty good value.

I will guess and break it down. $100 in material inc wastage which you have to pay for. That leaves $250 for labour, which is $125 each. So you think it can be done in less then an hour each...inc anodising?

Sure they are not cheap, but they are reasonably priced and having done these adaptors loads of time myself....you will be hard pressed to do it cheaper and get a known end result. My opinion only :cheers:

You're looking at it wrong. These are not being made as one offs. They are made in bulk. Maybe not huge numbers, but enough of a batch size to make the manufacturing more efficient. So on that basis, the material value in the adaptor itself wouldn't want to me be more than $25, including wastage. The fasteners are only going to be <$20 as well. Machining won't consume an hour each, and anodising is a batch process.

At $350/pr retail they are hard to justify. It would be hard to make them yourself at any decent saving, but that's not the point.

And I know what I'm talking about. I get stuff fabricated all the time, out of much more exotic materials than a bit of steel or 4041 (think inconel and other high temperature alloys - much harder to machine for a start). I know what one off cost and what you can save when the shop can tool up to do a run of them.

Diffence in opinion :) I will add what quantity do you think these are getting made in? I hear what you are saying, but it is likely to be quantities less then 10. Most shops would try and minimise the amount of dollars they have caught up in inventory.

Anyway, its a mute point. My perspective is if you are a business then you price a product to what the market will pay. And the average punter wont be able to do it much cheaper. Hell most punters wont be able to install the kit let along fabricate their own.

The beauty of forums are that you can learn so much and follow the DIY path. If you think its a rip and can do it cheaper then go for it. :thumbsup:

There is a guy (too much boost) selling a kit like this from SBS at the moment for a song at $500 inc rotors, calipers and mounts. just go buy that and sell your current calipers to an S13 owner. My thoughts are the 280mm kit is superior to the 296 kit anyways.

Yep $350 is probably too much for me. I thought there were other people on this forum who might have access to same/similar items for less.

Indeed you price at what the market will pay in order to get the best return. I don't think I will be paying $350 for these but I might (nahh...probably not). oohhh wait actually......meh.

Just buy these.... http://www.skylinesaustralia.com/forums/topic/385995-fs-330mm-big-brake-kit/page__p__6260824__hl__brake__fromsearch__1#entry6260824

$350 is a steal. By the time you mess around with someone machining them up and finding out they don't fit correctly blah, blah, blah...if they bolt on with simple cutting of backing plate then its a good deal. Many of the cheaper R33 kits are 3 piece brackets and that in my eyes is pretty nasty compared to the one piece UAS ones

have a look at this

http://www.ebay.com/...RS:1123&vxp=mtr

states 240sx(180sx s13) but its a direct bolt on for 32 gtr

also check these out the bolt up too will be gettin these for mine soon

They won't be a straight bolt up on an R32 GTR; you'll need a 340mm rotor.

If you have Z32 or R32 GTSt calipers, as std they run 280mm rotors.

R33 GTS25T and R32 GTR calipers have longer lugs to suit the larger diam 296mm rotors so if you were to use those brackets with R32 GTR calipers then the fit would be an absolute abomination, like posted above they are more suited to a 337-340mm rotor

how do u come to this conclusion ? "Abomination" ? I dont understand a few ppl i know have these on there cars and theyre fine 12.75 inch equals 324mm rotor which is r32 gtr vspec disc size or 350z standard rotors ppl want cheap and effective i dont understand where u get 340mm from

oh n one of those has a z32 300zx with them n theyre nuts

Travis, you're completely missing the point. The Autosport ones ONLY suit calipers that came on cars with 296mm rotors. The cheaper ones from eBay are designed to suit calipers from cars with 280mm rotors. If you look carefully at the two different adaptors you will see that they are completely different design. The cheaper ones just push the 280mm legged caliper out to the 324mm rotor position. It does that radially. The Autosport one pushes the 296mm legged caliper out to the 324mm rotor position also, but because there's not enough room to do this purely radially, the adaptor also has to move the caliper around circumfrentially a little to provide room for both sets of fasteners. THIS is the giveaway that tells you you're not looking at the same thing. If you apply the 280-324 adaptor to the 296mm caliper, it will push it out even further than the 324mm position. About 340mm in fact. It is important to remember that the Z32 uses the same sized caliper as the R32, not the R33.

You do understand that the calipers used on an R32 GTR ARE NOT the same as as an R32 GTR V Spec?

These adaptor will only work with R32 GTS or 200SX Calipers; the ones that go with a 280mm x 30mm rotor. This is how you get to a 324mm rotor. These brackets are designed to work with a 324mm x 30mm 350Z Brembo rotor; the offset of the GTR Brembo 324mm x 30mm rotor is unsuitable, and also more expensive.

Applying the same dimensions (a 44mm dia increase) using an R32 GTR Caliper (which uses a 296mm x 32mm rotor) ; you end up with a 340mm rotor.

This is the last post I will make on the subject; You can argue if you like, you can even go and buy the brackets. In fact, I encourage you to do so. thumbsup.gif

You will then discover that; surprise surprise, they don't fit.

I have no problem with cheap, effective improvements, but this will not be one.

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
