Personally not a fan of grooved and drilled discs as I have found the grooves can be noisy and you get more brake dust as they do what there supposed to cleaning up the face of the pad.
Car parts for less are pretty good. They stock Pagid discs and EBC performance pads and if you are clever with the discounts you can save some money.
Pagid 320mm cross drilled front discs £110 a pair

Pagid 288mm rear solid discs £69.50 a pair

EBC red stuff front pads, I use these and they do have very good reviews, next to no dust and very good performance. £93.44

EBC black stuff pads , these are essentially a standard pad compound £ 15

You get a 10% discount on all performance parts using discount code FAST10 so order the pads together as one order and these will work out at around £99.
For the front discs any order over £100 you get a £15 discount so order these as one order for £95.
Rear discs you get £5 on orders over £50 or £10 on orders over £75. So as the discs cost nearly £70 you could top that order up with £5 of something that you will then get free.
Either way rear discs £65.
£99 + £95 + £65 = £259 ish .
A better performing set than the ones linked above but they won't look quite as racy. I think all the parts should be correct for your car but check them.
You could order the fronts and pads now and do those and order the rear discs later.
