Everywhere I read people said that there was no point to it because the rears don't do much of the braking....
But after fitting the 312mm on the front it felt like the front brakes were doing ALL the work..
So when you take a look at the standard tiny rears (that look like they belong on a push bike) you can understand why...
So sod it I thought I'm doing the 256mm rears....
Parts you need are...
1. 256mm vented rear discs (I fitted TT225 Quattro ones)
2. Wider calipers from TT225 or Octavia 180 or similar.
3. Carriers from the Octavia 180 or Golf 1.8T 180 (TT225 Quattro will fit if you get spacers) (I used Octavia VRS 180 ones - easy bolt on)
4. You can re-use the standard Polo pads as they are exactly the same.
Worst bit of the job is cutting the lip off brake disc shields as they are too small to go round the 256mm discs.
Once all fitted you need to bleed bleed and bleed some more (pressure bleeder best - pedal pumping did not work to well)
Then let bed in... which mine are now just starting to do.
I have used plain discs all round to maintain a more stock look (and its cheaper..lol)
The complete set-up or fronts and rears feels so much more balanced.
Not pushed them hard yet but you can feel how much more positive the braking is - especially at high speed and with momentum. The brakes have some real stopping power now...
