so i've managed to get hold of some brembo's cheap ... off a 406 coupe ... do you guys think with some custom brackets they would fit under 16" wheels and 282mm discs ?

they are virtually the same mounting points so i thaught it wouldnt be to hard to adapt them ... 406 holes are 84mm apart ... my EK is 140mm apart. has anyone tried to do this before
 
go to a machinist and get them to make you custom brackets,anything can fit anything mate
 
Also i would imagine freaky parts could make some brackets for you
 
We can make custom brackets too. That's what we do with all our brake kits.
The 406 coupe uses 308x28mm thick discs, so fitting them to a 282x24 may have issues both with the lugs being too far away from the mount points (radially) and also when you have low pads as the disc is 4mm thinner.

If you want us to have a look and see if it's doable, you can send one of the calipers and we can mock it up on the bench with the hub and a standard disc.
It may be an option to use 300x28mm discs from the Accord Type R, as that will be closer to the original caliper requirements.

intresting well i was thinking using mg ZR discs ... as they are easy to fit to the civic and aprently you can use 282 discs with the brembo's ... or i dont think they would fit under my 16 inch rims ....

how much ish for a price ? i'm in france so wouldnt be easy shipping a caliper lol
 
The ZR discs are the same as the EK9 ones, 282x23-24mm. It still doesn't get around the smaller diameter the lugs on the calipers are designed for, or the thickness of the discs with the calipers being designed for 28mm thick discs.
Depending on how complicated the brackets are, they can be anything from £1-200 a pair including bolts/fixings.
I can also supply grooved discs as well for whatever model fits best.

well a friend of mine had them on his 205 gti with 282mm discs of an xantia so i dont know wether they are as thick ....

not really intrested in grooved discs at the moment il invest in them at a later date ...
 
Yes but it doesn't mean they were right :)
Depending on pad thickness, pistons move a maximum of 15-20mm over the life of the pad. If you're running a disc that's 4mm thinner than the calipers are designed for, your pistons will have to move an extra 2mm each over what they were designed to do, that's around 15% more.
The solution would be to fit the correct thickness discs with the calipers to reduce the risk of the pistons popping out when your pads are low.
A crude solution would be to fit spacer shims to the pads, but in reality you're going to get better heat dissipation from a 28mm thick disc than you would from a 24mm thick one as there's more metal.
Brakes are the single most important safety feature on a car so not something to try and cut corners on to save a couple of quid :)
 
In the same way as calipers designed to fit to another car are useless :) most things can be made to fit one way or another. If discs don't have the right stud pattern they can be redrilled (most of the time). If not there's plenty of ~300x28mm discs out there, not so many ~280x28mm
 
would the 300mm ones fit under 16 inch rims though ?

got any sugestions of strait bolt on discs in 300x28 ?
 
Our 300mm 2 piece kits fit under some 15" wheels :) it's more to do with caliper radius and wheel offset than disc diameter.
When you say bolt on what do you mean. The caliper won't bolt straight on, it will need brackets. If the discs need the PCD re-drilling that's nothing, a 5 minute job and probably no more than a tenner a disc depending on where you get them done

when i say bolt on i'm talking about the disc's i was hopinh to find a set of front disks that bolt strait on. i dont like the idea of re-drilling discs just seems a bit dangerous to be honest .... and having to drill them every time i need to change them is a bit of a bugger lol

i know that the calipers will need custom brackets.

how much are your disk kits then ? are they 300x28mm ?
 
There's a lot of discs out there which are drilled to 2 PCDs, like a 4x100 and 5x100. It's exactly the same with wheels. Many companies offer multi-fitment of alloys so they can offer them to a wider market. It doesn't mean they're any less quality. Drilling 3 more holes into the hat of the disc wont affect the structure of the disc at all.
For instance this link Brembo | Aftermarket Catalogue is for an OEM copy of an Audi S4 (1994-2001) brake disc. It is 320x30mm and has been drilled with 10 holes in the hat to reduce weight (I presume)
Firstly if Audi do it from the factory, I'm happy. Secondly if Brembo then replicate that disc exactly and are happy with the quality, so am I :)
Having to drill discs to a different PCD will cost no more than £10 and would take 5 minutes at any good engineering company. With any kits I make up which need this doing I then offer replacment discs in the future with the modifications done to allow it to fit with the kit, or if like you, the customer is an international one I supply the details of the modifications done so they can source locally.

A pair of front grooved Accord Type R discs would normally be £86 a pair, if they need modifying to fit they would be £96 a pair.

Saying that it is all theoretical. Without having the caliper on the bench, and the disc fitted to it, we wont know 100% whether they would work together, as the disc will need to have a deep enough offset to allow a bracket to get in there and fit to the hub. :)
