U can buy grooved drums yes.
WEll, my own experience of my rear discs.
PEdal feel increased. MUCH much better now.
Car definatly stops better
Feels more stable, but at high speed, stamping on the brakes makes the rear end a little twitchy.
NEVER had any problems with lock ups
I even remember when it first got done on corsas everyone saying it had a tendency to roll the car 
Oh, plus the fact they look 1000000000x better than drums.
Deffo worth it!

I've heard they just 'Overbrake' the car but if there set up properley they shouldn't.

no need for them. drums do enough with big discs up front.

You wouldn't think that a disc set-up is cheaper to make than a drum one would you..I wonder why company's still make cars with Drums?

The rears are only 15% of the braking anyway.

go for it, you can never have too much stopping power, especially with the engine you have planned

Spot on. If it's looks you're after, by all means, go for rear discs. But if it's stopping power you want, keep the drums and spend the extra on even better front brakes. Fronts do most of the braking anyway, and when you fit better brakes up front, there's even more weight transfer to the front, which means that the rears do even less

25% on the corsas.
Vibrio, warrent the extra cash, what, u mean £20 for the rear calipers and a days work fitting them. Electricty doesn't cost much.
And i presume you have driven a corsa without rear discs and a corsa with rear discs?
Funny how everyone who has rear disc conversion agrees it makes the car stop much better, and everyone who hasnt' says its a waste of time

Daimo - not disputing that there might be 'some' improvement with rear discs. But in the post on V6 brakes, you said:
"Stamp your foot on some 4 pot calipers and you'll see where the extra hundreds go Also, 4 pots are usually about 1kg each. V6 calipers are about 10kg each!
I've got V6 brakes, and as soon as i can safly afford £700 on a set of 300mm brakes/calipers etc, im buying them
Not for a few years yet though "
All I'm saying is that Matt should concentrate on spending as much as is needed to get the fronts right before thinking about doing anything to the rears. And while the pedal feel might be improved when u combine rear discs with V6 brakes, you haven't got 4-pots on like I have; if you did, you'd realise that the pedal feel is already excellent.

Oh yeah, but this isn't about front brakes, this is about rear brakes. And i have driven cars with 4 pots on the front yes so know how they stop 
Im just saying, my car works very well now the rear discs are on and everyone who i've spoken to who has them has agreed. Mostly with different brake setups up front too. Even the car Desmond bought and wrecked with the 19"s. That had Brembo front end and rear discs, that stopped on a penny.
Rear discs cost the price of the calipers/discs etc and the price of a nova handbrake cable (£8). A days work, and ur sorted.
And they look a million times better than drums as i said earlier

so £20 is all it costs for rear discs to be put on a corsa

Well, i got my rear discs for nothing. Maybe £20-£30 from a scrappy.
Rear nova handbrake cable = £7-£8
And some tools.
So no, its not expensive at all
