How easy is a rear disc and pad change on a 2012 VRS? Mine are looking very corroded round the edges now, and it's been noted by a couple of garages now. I've done the rear brakes on a Mk1 MX5, is it any more complex? Any special tools needed?

You'll need a caliper rewind tool to twist the pistons back into the calipers.

Also the caliper carrier bolts can be a nightmare with the awkward allen key head.

As with all brake caliper and disc changes. Check the condition of the rubber dust sleeves. If they're torn or distorted, then don't ignore. Moisture gets in and the rest us as they say history.

Haven't done rear disks on a Skoda (damn rear drums on mine). Draper make a half decent rewind tool which is invaluable. Also arm yourself with Lockheed red grease to grease under dust sleeve and slider pins, and copper ease on pad edges and piston face. Draper also do 7mm Allen key tool which is fantastic.
