I looked into it but from what I'm told s3 brakes wont fit under 17's so its £500 for the brakes then the same again at least for new wheels, but i could get the gti brakes with yellow stuff pads for between £200 to £300.
Hey bud. S3 stoppers do fit under 17s. I would not bother with the upgrade to 312s and instead go straight to the S3/R32 units.
I have 17 x 7.5 ET56 at the front and have around 10mm caliper to wheel on the side, about 15mm rear spoke to caliper, and about 4mm caliper to wheel weight.

hereCar is coming along nicely bud, hoping to see some good progress. Not sure on tuning of the CRs, the PD140s eat turbos so you need to watch out on them, hopefully the CR ones are a bit stronger! If it has a DPF get that removed and it'll feel like a whole new car along side a remap!
