its up to you what to do, but i dont think there is any need at all to have V6 brakes on a corsa that weighs sod all and doesnt go fast enough to warrant having massive brakes

yes there are 2 types of calipers. some have 56mm pistons IIRC and some have 52mm IIRC, there is a great difference between the performance of each of them, ie the small piston ones dont have as much bite at all from what i have found.
Cav/Calibra turbo brakes are generally the smaller piston, and the Cav/Calibra V6 and most of the high spec Vectras have the bigger pistons.

yes true  which is basicaly my disadvantage for spending the money on brakes, and getting the inlet first lol
but it does look good lol

I can't comment on greenstuff for corsas....
But on a VX they are fucking shite....no let me re phrase that.
Nigh on deadly.
I thought they were ok for a while, then when the pads more than 50% worn they were downright useless/dangerous.
Just my 2p's worth

was that when warmed up fully or when the brakes are cold?

my corsa has ABS and the V6 brakes were shocking on it. Pedal travel was about 12cm and really spongey, bled twice and was no better.
They also had braided hoses.
Got 2litre brakes on it now, pedal travel is the same as on standard brakes and they clamp better.

could that be something to do with the spongyness of some and others not?
although i suppose its using two different brake set ups anyway, turbo and v6, but do the bigger pistons cause a more spongy feeling maybe?

I had standard size 'sports' discs from a well known manufacturer, with green stuff pads on my standard Corsa 1.4 Sport.
I warped them, and they faded all over the shop.
I had 288mm V6 discs and calipers, using STANDARD GM discs and pads with goodridge hoses, on my 130bhp 1.6 Corsa Sport.
I didn't warp them, they didn't fade, not once, not even round Milton Keynes at warp speed.
IMO, upgrading your brakes properly is better than spending money on an inlet.
Oh, and I had my V6 ones on my car for a good 6000 miles, using them hard all the time, and when Rick bought the car off me, they were not worn at all, not even slightly.
My car weighed sod all too, so clearly didn't need decent brakes.

yes that is generally the cause. but if you go for 288mm (284mm) brakes with the smaller pistons, you may aswell go for GTE 256mm brakes as the pistons are the same size, unless you really want the big disks.
Another alternative and maybe more for your needs if you want nice looking brakes would be to get GTE 256mm Calipers and get Hi-Spec big disk kit which spaces the caliper and you get disks with anodized alloy bells which look rather cool, but you wont get any spongy pedal etc

your correct there Robin on the warping disks front of things, although i have owner numerous sets of Tarox disks on different cars and have not warped one set even after giving them absolute death and after hitting puddles when they are hot, although i have also owned EBC disks, and heard about those 3G shite and load of others and they have all warped under normal use and hitting puddles.
you are also correct about the GM disks if you do go V6, they are the best ones to have and i have yet to hear of a set warping. and yes, on a corsa or astra etc the V6 brakes dont seem to wear at all hardly even after hard use.
and you are also correct about upgrading brakes is important, although maybe there are cheaper alternatives that will get nearly as good results without having to cough up loads of money. such as good 256's with good fluid. Have you ever used a car with properly bled 256's running DOT 5.1? i think you may be surprised as to how well they work and how they dont fade.

I think the ABS module plays a big part on how spongey they V6 brakes are. If you dont have ABS then the v6 brakes should be ok.

Nope, the only car I've had with 256s on was my Nova, and the less said about the brakes on that the better

Again, I cant really comment in terms of corsas because we are talking different cars and brakes.
On the vx greenstuff were utter rubbish cold and hot (given my post above)
After a few miles on the vx greenstuff gave no feedback when cold and major fade when hot.
Im now running dot 5.1, standard hoses, ap two pots, mintex 1144, and standard disks.
believe me....my car stops big time now

good mate of mine had an XE nova on 256's and his were really really good, locked up on command with his brakes. and they didnt have D)T 5.1 or braided lines, just bog standard
think its down to personal choice with Vaux brakes, but having owned all that have been stated i would say that there is no noticable difference between V6's and good 256's bled properly on a Corsa or Nova.
Think having decent pads and decent disks along with being bled properly plays the main part in good brakes on a lightweight car.
