Of brakes and men.

And here we have it after months of waiting until the right time to get it done : the 310 (and presumably 312)mm brake set up fits cleanly under 6-spoke SE 16" rims by at least half an inch clear air outside the caliper. I also have new brake discs & pads (standard 256mm) fitted to my project car a week later on the same rims, both sets fitted using braided WG/Hel brake lines, which means I have a direct comparison to how they were previously and the bigger brake setup.

Firstly - in normal commuting - the big brakes feel more progressive - there is very slightly greater pedal travel range as predicted by @DuncanA2 above, but it feels to me as if there is more precision / feel over the pedal movement range. Ironically the pedal now feels almost exactly like the one in my A6 which has 312mm brakes. On my project car, the key thing is more firmness and bite to the brake pedal (unsurprising given the state of the discs / pads that came off it). Both are an improvement in perceived pedal feel, but in different ways.

Herewith a photo of the new setup while I was swapping to winter wheels at the weekend ; they are barely visible when the wheels are in situ which is what I was looking for - I just can't get a good angle to take a photo with the wheels on right now owing to driveway occupancy.

Depends what you mean by "need to know about the conversion" - by all means ask a question if anything comes to mind. I'm no mechanical expert - I worked out what was needed from a variety of threads here and other reading (detailed in the posts above including the entire parts list and sources), and ultimately having put the pile of parts together, my local mechanic assembled them into a whole then swapped them on.
Back plates were the one thing where I drew a blank. Recommended backplates for the larger discs from the diagrams were obtained from Crewe Audi, and they don't fit - fortunately not that expensive so I've swallowed that one as having sourced the wrong part.

I can definitely recommend the HEL brake lines as well - these were retrofitted onto the other A2s with conventional brakes in place of 20-year old originals and look better at the very least.

The brake plates are all the same on the Audi A2 256mm front brakes, and the VW Polo MK4 239mm/256mm/288mm/312mm front brakes.

I suspect Crewe Audi sent you front brake plates from a different car, such as VW Golf MK4 or Audi TT MK1, which are different.

Do your brake plates look like the photos below which should be correct? Have you got the OEM part numbers of the front brake plates that Audi Crewe sent you?

There shouldn't be any need to purchase different front brake plates with a 288mm or 310mm/312mm big front brake conversion, as the front brake plates from the Audi A2 with 256mm front brakes should fit correctly.

don't have a clue - from very distant memory was looking for the ones with a 6R (?) or 3C starting suffix. Whatever they were didn't have the correct bolt-hole pattern to fit the hub carriers, so in the end I stopped worrying about it after experience on a number of cars of the back plate exacerbating corrosion and trapped gravel chip noises on front brake discs. MOT tester wasn't bothered about it being absent as long as the brakes were in good condition so that was that.
 
Just the part numbers were updated, newest are 6R0615311A and 6R0615312A. I installed Topran 116445 and 116446 on my 288s.
