Brake advice

[audi-tone]

Hi fellas. It's time to Change the front pads so while I'm at it I'm going to upgrade to 312mm while I have it apart.
I plan to get the rotors and pads from gslrallysport but Where's the best place to get the carriers? I know ecs does them for 100 each and the dealers do them for 400 each. But do I need any sort of spacers aswell or is a straight swap from the Audi tt 1.8t / s3 / bora vr6?
Cheers.

I'm getting my carriers from WHEELS & BRAKES Welcome to German Auto Spares - German Auto Spares - suppliers of VAG Febi Car Spare Parts
When I included shipping they were the cheapest(email them)
Mine should be here this week, will let you know how smooth it goes.
You need 1J0615125A , ECS have them on special, I missed out DOH!!!!
