Having just bought a Touran to cart the kids around in I'm not impressed with the brakes at all. Does anyone know if there's a bigger brake setup that would be a straight fit from another VAG car? I know mk5/6 Golf's are the same pcd and centre bore, and some high powered Audi's, but I just lack the knowledge and knowhow if there's a straight swap available with calipers and carriers.

On the Vectra derv, I had the setup from the V6 fitted and the difference was very noticeable.
