The black MY08 rear calipers dont early cars
 

Had quite a lot of calls and emails about fitting the MY08 rear black brembo calipers to the earlier models , as most of you know the Gold brembo's will fit on the Classic with a bracket , and fit straight onto the My01 - 07 WRX's.

The Black MY08 calipers will not fit onto the rears , the lug spacings and offsets are totally different from the Gold ones ,

Here is a picture of the gold calipers in place on a classic hub and 316mm disc ,you can see that the lugs fit inbetween the lugs on the hubs , the bracket kit we make bolts everything in place.

When fitting the black MY08 caliper onto the 316mm disc , the bolt spacings are different to the bolt spacings on the Gold brembo's , where the gold Brembo's fit inbetween the lugs on the backplate , the black calipers line up with them , the caliper will not go onto the discs as its hitting the lugs on the backplate.

There is no way that these can be fitted with a bracket , I have seen a few places advertising them to fit the classics , save your money and leave them there.

Hope this helps

Cheers Ian

just a passing comment as not had a chance to "marry up" an 08 caliper, but can these not be spaced so that the lugs sit 'fore & aft' of the other pair of lugs on the backing plate if you get my drift??

cheers, alyn

Why can't the back plate be trimmed ?:)

If you see the picture of the black caliipers in place , you can see that the caliper is not all the way on the disc and the lugs are tight up against the backplate , if you try and take the caliper up or down , the lugs on the backplate push the caliper further out , I did try that

Cheers Ian

The lip around the edge of the backplate is what gives it its strength , you start cutting that and it will become unsafe , to get the caliper in its correct position would mean having to cut loads away , it would be too unsafe.

Cheers Ian

Just bought a full set of theses calipers off ebay.:(

Thats why I started this thread , I have had quite a few calls from people who have bought them , as that guy on ebay selling them is saying they will fit with a bracket , but they dont.

maybe wasn't clear............can you not move the caliper fore (or aft) so that one of the lugs sits up in between the caliper mounts and hence an offset brkt??

Hi Alyn
Yes I knew what you meant , if you move the caliper up or down on the hub , the lugs on the backplate push the caliper out even further , it wont fit ,
I have tried it in all positions ( and the calipers :D )

Cheers Ian

Me 2! Pushing back for my money back or a discount!

Looking at that first photo, what's stopping the caliper rotating slightly AROUND the disc, so that one of it's lugs sits inside the two backplate lugs, and one of the backplate lugs sits inside the two caliper lugs?

Paid for mine on the 6th of july & ive still not got them!:mad:

In the photo , you will see that the caliper isn't all the way on the disc and the lugs are hitting each other , if you move the caliper round so the lugs fit in the middle of the others , it pushes the caliper even further off the disc.

I have tried it all ways , and they wont fit , and I like a challenge !

Cheers Ian

Reality check:D :D :D

Depending on what you paid ? the price is fair even if you end up with just the fronts.:) You get...

x2 new brembo front discs
x2 new brembo rear discs
x2 new Brembo front calipers including new lines
x2 pairs new Brembo front pads
x2 New Brembo rear calipers including new lines
x2 pairs new Brembo rear pads

On the basis that Ian was selling rears with the conversion for £650 I recon they are bang on the money (although disappointing I know). I paid £650 which is still cheap when you tot up whats included. 18 months ago I paid £550 for a set of low mileage front brembos with discs and pads on their own.

So you can't use the rears, no biggy tbh I bought brand new rear brembos, discs and pads for £200 and will sell them on when I work out how to fit the black ones:)

FWIW the guy that sold them said he had manufactured a bracket to fit them to a New Age WRX. He could be taking boliox or it could be a fook awful install, but I still think by altering the backing plate and using the existing godspeed spacers a solution can be found. Certainly from the pictures, and from what I looked at when fitting the gold brembos, very little needs to be trimmed. Although I do say that without the expertise of Ian and I am in no way wishing to doubt him:thumb: I would like to have a go at doing it though:lol1:

At the end of the day I would still have paid £650 just for the amount included, even knowing that the rears were a lost cause:thumb:

I suspect they will fit, but they are not the business opurtunity they first seemed. ie, it will take a fair amount of fabricating rather than a very simple bracket as per the gold brembos. In other words not cost effective......

To simply write them off as not being do-able is a little extreme.

brembo black
 

hi, ian its hard to see in photo but the bolt centres look the same in back plate and the black brembos? yes/no

if 'yes' and you 'could' use the original bolt holes would the caliper be in the right place for the disc in the respect of diameter clearance, ie outer circumference of disc correct place in caliper?

Are the pads in the black caliper in the photo?

if the above is right could you and i might be talking rubbish and tell me if i am.

machine minimum amount of the threaded location from black calipers to get them to sit in between disc and backplate as this seems to be thicker than the gold ones?
If this removes to much material maybe do this and add small spacer beween hub and disc?

hope this might help but i haven't seen any of this in the flesh so just throwing ideas out.

thanks steve

Would it not be possible to use a larger disc diameter with a suitable bracket for the Black calipers, pushing the caliper outwards to fit a larger disc diameter?

Just my thoughts from looking at your pictures Ian.:)

Like your thinking :thumb: :thumb: :thumb:

Ok , as you know better than me , go ahead and make them then !
I am not simply writing them off , what a fricking stupid thing to say ...


It doesn't matter to me what shape the brackets would be , I simply make a CAD drawing of them , transfer that to a CNC laser cutter and it will cut out any shape and size very very easily, when making and designing a bracket you need to be able to see the 2 holes on the caliper , and the 2 holes on the hub to fit a bracket in place and bolt it on , to get the black caliper to sit onto the disc so the pad fits correctly means it has to go further onto the disc than it is , look at the picture from above and you will see quite a bit of disc that you cannot see in the picture of the gold caliper which is sitting on the disc correctly , the lugs on the calipers and backplate will not let the caliper go onto the disc as it should , moving the caliper left and right on the hub doesn't make it fit either , it is worse in fact as if you put the lugs on the hub in the middle of the caliper lugs , the caliper lugs hit the backplate which pushes the caliper even further off the disc.

Take it from me , without cutting the backplate down and fabricating a new shape , it will not fit , period. The lip on the outer edge of the backplate is what gives it its strength , to cut that away to try and make something fit will weaken it , and the calipers will end up tearing off , it is not a safe thing to do.

Cheers Ian

Yes the bolt spacings are the same , the caliper I had was a customers so I couldn't go chopping it up , if you want to donate a caliper then I can try it out , I did have a look at it , and it looked like the 316mm disc would be too large , so I think it would need reducing in diameter , and the pads machining down to suit , but it's possible it could work. It depends also on how much thickness is left on the caliper lugs to keep it safe .I would guess that about half the thickness would need to be removed for it to fit


Cheres Ian

Yes that is an option , you would need to fit about a 370mm ish disc for it to fit ,the problems you may have then , is finding that size disc thin enough to fit into the caliper , usually larger diameter discs also get thicker , then seeing if the inside radius of the caliper will take the shape of disc , as the larger diameter , the outside radius gets straighter , and then running a large enough disc on the front to keep the ballance right. it is an option but still with its problems

Cheers Ian

If it helps the guy i bought them off has said he would happly take them back at the same cost i bought them at! :wonder:

Mmmmmmm, your quote :wonder:

Those wanting black calipers for the rear use the 2pot my01 version 290mm discs and brackets.

thought this may be an option looking at photos,
removing half the lug would be a bit much i think, need to retain more for strength. have the black brembos got a wider lug?

Reducing disc diameter is not a problem looking at the photos it must be a minimal amount 5mm-10mm at most?

Is it possible to use a thin spacer inbetween disc and hub? downside being increased track/wheel bearing load etc.

if this does work could you offer conversion on exchange basis?

eg spacer/reduced disc/pads, machining of calipers etc

thanks steve.

hi, andy,

how does this work? The bracket would take caliper further out from disc?

I'm sure its been looked into, but how about fitting a later back plate?
I'm sure they are expensive from a dealer, if you can get them at all, but once there is a protoype they could be fabricated.
Just my two pence.

This may seem a bit simplistic but can the backplate not be changed to an 08 backplate or do these not fit the new age hubs :wonder:
I am with Ian wouldnt entertain messing with the structural strength of the backplate by cutting it.
