OEM discs were Renault's own rears and Brembo fronts as far as I know from a few years of reading CS
OEM pads
are Brembo all round. It's the bearings to watch out for though.
Adam @ Wolverhampton
is the UK distribution centre that sends stock to dealerships, garages, random ebay traders etc. You simply are not going to get OEM bits cheaper than Adam unless people buy their stock from Adam and then sell it on ebay at a loss lol.
Renault Wolverhampton: 0844 558 8799. Only speak to Adam Greenhouse. If you're looking at ebay cause you want them quickly... well then no-one's going to dispatch them on Sunday anyway and Adam can usually offer very fast and very cheap postage.
As I said, rear discs and pads are £99 inc. VAT as of this week (

To avoid CS.net exploding please please please
insist that your garage is extra vigilant and removes the spacer which will no doubt be stuck to the old disc (or goes flying 20 feet if the disc is difficult to get off and needs some hammer action) and refit it with the new discs. If the spacer is lost, broken or non existent then again Adam is the cheapest. Part number is 6000073518. You'll need two of them.
If you're considering front discs too then the forum seems to prefer G172 (
http://www.cliosport.net/forum/forumdisplay.php?147-G-172) for Brembo HC discs. If Adam & G172 are within a few £ on the front discs/pads then you may as well just buy the lot from Adam for the sake of simplicity/postage.
Back to spacers if I may. Unless it's a specialist they'll probably go "yeah yeah mate you can trust us we do clios all the time" and think you're a **** for telling them how to do they're job. But there is virtually nothing indicating that you need a spacer, it's very easy to miss as it'll be corroded onto the old disc and hidden with dirt and most cars don't need spacers between the disc and hub so why would the mechanic even be looking out for one?
