Will probably need to replace discs/pads in the near future so question is oem or aftermarket? Any recommendations?

Will consider anything but must be something of good quality as I don't want any aspect of this car to let it down - especially brakes!!!

I don't want something that costs an absolute fortune either though... Have to be realistic here.

I know the original brakes are very good and I've never felt like I needed bigger/better brakes. But with m50 manifold and exhaust installed and maybe a couple of more performance mods in the future, might be good to upgrade brakes now while I'm at it.

So with the above in mind, any ideas?
