Brilliant info, just bought my discs ( £48 each ) from Andrew Page. Part No MDC1941. Just need to get the centre spacers made up. What a great Forum !!

Whilst it isnt a big deal, the Monaro AP's are 362x32mm

So you're losing a little on the diameter...no big deal, but also losing another 2mm on thickness.

Again, not a huge deal, but dont let pads get too low, as effectively you're running very worn discs as far as original fitment goes.

But great there is a cheap alternative to the bumpy expensive AP discs

At £48 a piece that's a lot of new "worn" discs per one AP!

Absolutely....but just a warning in case some like to run their brake pads right down to the metal.

Worn pads with even further worn discs could result in no pads, and no brakes. So ensure early maintenance !

There could be less or more in this statement.

If the thickness difference is metal thickness, then I agree it would be like starting with a worn disc. However, if the difference in thickness is in the air gap between inner and outer surfaces (assuming they are all vented) then it could lead to overheating in extreme conditions.

As far as pad material and time/wear before the pistons pop out of the caliper....the discs are worn vs original AP.

Doesnt matter if the disc is solid or vented, it's starting with 2mm less thickness than the kit was designed around.

But not a big deal, just something to be aware of.

And I'd hope anyone opting for the cheap discs werent going to pushing things to extreme in the first place, although I doubt there are many owners here who would be doing that anyway. Monaro isnt a popular track car etc.

Although 360x30 is still a whopper of a disc by any standards.

To remove the potential problem of the pistons traveling out of the caliper to far couldn't you but a 1mm shim behind each pad. It wouldn't stop you wearing the pad to the metal and beyond but would start/stop the pistons in the original positions

Why would anyone cut corners on brakes unless you are fully retarded

If you can not afford to use the correct parts for the vehicle you obviously should not be driving or owning the car

Dowels , spacers & pretty much spot on ! `F*** that

That's a clever use of language. biggrin

As for the rest of your comments, if you were racing, then I'd agree, but I think that very few will find the limit of the setup - especially when you compare them to the standard offerings on a CV8.

Correct parts would not be AP stuff then.....they would be OEM brakes wink

and I think it's no secret that between bumpy discs, corroding discs etc etc...the AP discs are far from perfect on this application.

The Land Rover discs could well be considered an upgrade for road use over the AP's !

And as with all changes to the original specification, remember to TELL YOUR INSURER soapbox

I deal with Land & Range Rovers every day & nothing would be a upgrade fitted to a Massey 135 let alone a fast road car

But these arent a Land Rover made part, just fitment.

Yes I know my point exactly the spurious parts are terrible , anything apart from Oem on a Defender everything else gets Genuine only fitted

Depends on how much of the vehicle has corroded away on your drive overnight

Fair point. Lots of cheap replacement parts are pretty crap these days !

Lots of good discussion here - and its true its to everyone's taste. I've detailed something that works very well for me.

From my perspective, I use the car for maybe 2500 track-day miles per year, plus about the same on the road. And believe me, it gets well used, too. I've found that the Land Rover discs, together with the appropriate pads offer me better braking than any other vehicle on track, even Caterhams, etc. - probably the only place that I get a real advantage.

I do also have some "insider knowledge", having been in the vehicle design industry for 20+ years now. The discs have been fully tested and carefully monitored. I have the entire braking system analysed in an industry-standard tool for adhesion, bias, etc. - and whilst the AP set-up isn't the best one I've come across, its certainly very good. Saloon cars are very difficult to get right, as there is a large difference between weight split between empty and four people with luggage and fuel.

Hi Chaps, sorry to resurrect this old thread! I'm currently looking for discs front and rear to replace my worn out AP discs. I think i'll be going down the landrover discs route as the prices are way more cost effective than the crazy prices I've been quoted for ap replacements. I only do 5k miles pa and am mostly commuting in the car. One day a week I may go on a "run". I don't really need ap discs.
Looking at the comments above,

1)as I need front's and rears, do the landrover ones fit?
2)I appreciate they are slightly smaller and will need spacers. Any ideas where to get them from?
3)looking on euro car parts the brembo's are £80 odd each - the pagids are a little bit cheaper. Are these ok as replacements?
4)anything else I need to know before buying some discs?

Cheers thumbup
Simon
