Brake disc thickness?

Hi all,

Seem to be having an issue finding the answer - probably because it's printed on the discs, but I can't tell because mine are rusted :) What's the minimum thickness of front/rear discs?

My fronts are at 34mm, rears at 26mm, I think I'm at end of useful life for them?

Cheers!

Min thickness is listed as 34.4 & 26.4 if I recall correctly.

Yikes. So both fronts and rears are gone? Argh...

I've never had discs go past their min thickness, but how much further can I go on these realistically? I just got the oil leak sorted, I need some air before I drop $3K on brakes. Heh.

Front and rear discs and pads can be had for £1122 through carparts4less if that's any help

I have no idea why but euro seem to think it's acceptable to charge such a markup on them, nearly every other brake product for any other car is usually within a few percent different between the two companies, maybe it's the RS models only but why can cp4l charge 60% less on something so expensive

Wow, that's actually a pretty decent price, thanks! And it's the elusive Pagid discs that I've been looking for! Cheers. I was basically almost set to buy the AP Racing discs, I know they're quite good, but the absolute cheapest I found them with the bells was £400ea ex VAT for fronts only, which is .... a lot. This might work better now, if only I can figure out how to get them out to the Far East... heh.

I've AP calipers, discs and Ferodo ds2500 on the front of mine, with ap discs and ds2500 coming for the rear shortly. They're a fantastic piece of kit, and if you can manage to stretch to the ap pieces you'll not be disappointed.

However the pagid stuff is cheap and cheerful with oem quality which isn't terrible
