Peugeot 406 rotors -> MA61 help!!	Sun, 29 August 2004 08:48

Ok here is the situation the peugeot 406 rotors are: - 283mm diameter - 28.2mm height - 26mm disc thickness - 66mm center bore - 4x110 bolt battern Now im not undertaking the 5 stud swap, and i have 16in rims so it will all fit. Is it just the case of machining out the center bore to 76mm stock MA61 and redrilling the bolt pattern to suit the MA61. Going to pair this up with the Z31 calipers. Just thought i'd post this for others contemplating a brake upgrade without a 5 stud swap (who have bigger rims). [Report message to a moderator]

you cant redrill disks. Ive spoken to an engineer just today about this and he tells me it is just NOT safe. i was going to use BMW rotors on my ma61, but have had to change plans because of this same reason. [Report message to a moderator]

changing 4110 to 4114.3 is nothing hardly redrilling. but you get the disks as blanks and can put what ever hole pattern you want. [Report message to a moderator]

Yes you can get blank discs, but you have to wait for them, especially if you want something as weird as those X5 ones. [Report message to a moderator]

Apparently most, but not all, discs are available as blanks. I contacted DBA and was told that these particular Pug ones were not available as blanks. [Report message to a moderator]

This is because DBA do not actualy make the Peugeot disk, they source them from Brembo or someone else. They only make the more popular models, the ecconomics of manufacturing... Im sure Commodore disks will be avaliable with no holes. [Report message to a moderator]

Well I've had it done and it's not dodgy at all - or else I wouldn't be doing it. And believe me, I am mates with Norbie, I know all about dodgy I paid an engineering shop to set my rotors & hubs up on a jig and make sure everything was square (well, round) and redrill the holes. Keep in mind that you're talking a difference of about 1mm... and if it's done correctly then there will be no movement or play at all. One thing I would never do is undertake a major change though (eg redrilling discs or drums from 4 to 5 stud) as this does nothing to embiggen your level of safety. I'm also not convinced about how cromulent some of these "multifit" rims are strength-wise! [Updated on: Sun, 29 August 2004 12:49] [Report message to a moderator]

btw: you would be drilling them to 4 x 100mm (i think) - thats the PCD of the rotor mounting face, not the wheel mounting (which is 114.3mm). id be talking to an engineer, specifically the one you plan to have it passed through, before finally determining ANY course of action.

I did re-drill BMW rotors to 114.3 and it docent look dodgy at all. Holes are oval shaped by about 2.5mm. You can't notice it at quick glance.

Bolt holes doesnt carry the weight of the car. Spigot hole does. The rotors still does have the lock screw holes. Ovals are directed to outwards from center point. Safe IMHO. [Updated on: Sun, 29 August 2004 13:21] [Report message to a moderator]

just for interest Look at the ba upgrade. the centre hole in the BA rotor is 71.5mm, where as the strut its going onto, is 60mm..obviiously everything else would need to be pretty similar for it to be 100% safe as it would rely on the bolts..I mean yeah sure, the caliper is still bolted on there, but brakes arent something i wouldnt want to be uncertain about.

Glen,

I saw this late, but would like to make a few comments ;

Are you mounting the rotors as the back of the stubs like std ?

Have a look at a disc selected by rsdea on CelicaSupra.com. as he picked out a disc from the PT Cruiser and using the Z32 calipers.

Redrilling the disc mounting bolts is not really a problem, as long as it is done well.

I can dig up the link from CS if you want.

Cheers

There is also a disc from a lotus elise which is a 5000 series two piece job, dba 5355. The dimensions are 280x26mm and an overall hight of 29.3mm. I am looking at using this with Z32 non turbo calipers. [Report message to a moderator]

If you want to try the 406 disc then you may want to use the '90 NA Z32 caliper. It is narrower and designed for a 26mm or 28mm disc. I'm assuming you want to mount this disc on the back of the MA6x hub like stock. I think the offset may be off. Or are you using another hub that is 5 bolt? Here are the specs of the stock MA6x front disc. Here are the specs of the '90 NA Z32 front disc. Here are the specs of the Turbo Z32 front disc. Here it is.... early Z31 hub and PT Cruser disc center hole opened to 81mm. Redrilling is no problem. Done by many here in North America all the time. Here is a Z32 disc redrilled to 4 bolt for an S12. I'm working on a 5x114.3 hub that will mount on any MA6x and will accept the stock Z32 disc with no modifications to it. The Z32 caliper will also bolt straight to the MA6x strut stock cliper mounts. How does that sound? Will know for sure next week once I get all the parts. It is going to be really close fit. Wish me luck. [Updated on: Tue, 31 August 2004 02:33] [Report message to a moderator]

I have a set of 16in simmons rims already so i really don't want to have to go 5 stud, however i would like larger brakes. Yes, i want to mount the 406 disc to the rear of the hub like the factory MA61 rotor. Yes, i was intending to run the 26mm N/A Z31 caliper. The overall disc height is only 28mm compared to the stock 26mm. This shouldn't affect the offset too greatly! I really need a dummy strut to play with..... [Report message to a moderator]

I figure-eighted (drilled the hole so that it broke into the existing hole)the rotor mounting holes in my car and then spot faced the new holes on centre, made some washers that fitted the spot face (washers are about 4mm thick) and mounted them up. I did it this way because it was the best way I could see to do it at the time. The pics above showing rotors that are retained by the wheel are no problem with elongated holes. You can go for VT Holden rotors and mount them over the front of the hub (it usually requires the hub to be turned down a smidge). There are rotors available un drilled for these from Pittwater Brake and Clutch (don't know if any of this helps). [Report message to a moderator]

I didn't realise that the Z31 were for 26mm discs.

I have some struts spare !!!!

On a side note, if you can, use RA60 struts (readily available and dirt cheap) as it will get you a bit more neg camber for free !!!!

Unfortunately I think what you are trying to do, mounting a 406 disc on a stock hub, will not work due to the disc offset. Yes the offset will be close to stock, but the Z32 caliper center is farther out than the sock caliper.

Getting some spare struts as I have will help in choosing a proper disc. Another thing to consider if you want to stick to 4 bolt is using early NA Z31 hubs. This may help in disc selection.

Seen this done, but the rear of the disc may sit too far back. The disc could be turned around and spacer used..... but harder for air to run through the center to the vents with less space. [Report message to a moderator]
