The Audi TT and S3 are the way to go has all the front end parts e.g wishbones and hub carriers are alloy. The TT also have adjustable lower ball joints and wishbones and both have solid front wishbone rear bushes.
I have just replaced the front wishbones and hub carriers for the S3 items, the S3 not sure about the TT have a slightly wider track at the front than the golf.
Feels miles better and the difference in turn in and feel are so much sharper.
