Rear Discs
My rear discs have started to corrode slightly around the edges and centre, leaving around 45% of the disc 'clean' - Tom (TGM) advised that they probably have a few thousand miles left on them and should think about replacing them soon.
I do motorway driving on a daily basis - around 65 miles per day. The journey home normally consists of some B roads as it makes a nice change from the concrete greyness that is the M25 on the way home, and keeps me awake a bit - and of course, i get to enjoy the car a tad more!
I've had a look at brakes international and they have the rear discs listed up at about

No power or life to be gained (poss a bit of life lost). the grooves are there to keep the glaze/dust off the pads. I've just upgraded my discs & pads and the rear discs are the only bit I've left stock. Just stick with OEM IMO.

if anything, slotted discs will just reduce the life of the pads.

ive replaced my discs (all four )for a similar reason, i only had 50 or 60%of wear pattern on the back due to corrosion . I would say that you will notice a huge diffrence by just putting ordinary discs on the back never mind grooved atleast the pads will have nice clean metal to bite on

Apologies here for slightly sidetracking the original post but the question is related.
It's regularly written and said that when changing pad types that to retain braking balance you should replace both front and rear with the same pads.
Is it the same deal with rotors? ie, you have an aftermarket rotor at the front and an OEM at the rear with the same pads all round; will this alter the braking balance sufficiently to upset balance front-rear?
I would have thought so but I also imagine that there's room for experimentation here.
Reason I ask is that I'm looking to replace the rotors at some future point and am wondering whether I should be looking at all four corners or just Fronts DBA4000 and rears OEM with Ferodo DS2500 pads all round but I'd be concerned about ruining the braking balance by doing this.
Lower; are you running with DBA4000's all round?

I've only put the DBA's on the front and have OEM's on the back.
I'd say make sure you use the same pads front and rear, but the frictional properties of the disc don't change significantly so won't affect the brake balance.

DBA fronts and OEM (Brakes International) rears here too. Redstuff Ceramic pads though.

Guy here had his rear disc locked on in his s2000 a few weeks back, he got out and it was bright red so a bit hot 
His brother disconnected the rears and drove it 70 miles with only the front brakes connected back to his garage to fix
