Whist racing last year it became apparent that we were a little down on front end camber. Looking at some of the faster cars in the corners they had significantly more negative camber:
There's a really good post on TT Suspension here: TT Suspension
On the stock Audi TT you can get a max of -1 degree of negative camber so some work was needed to get some more. There are various solutions, you can fit adjustable top mounts at around £400 and get a further 1 degree, or fit new modified wishbones for around the same price and get a little more. The thing is we don’t know how much we need yet so we wanted a more cost effective solution.
Some people cut and shut the wishbones but I didn’t like the sound of that, another solution was to modify the ball joints. Then looking around at the various ball joints available I noticed that the Mk2 Audi TT ball joints were spaced further from the bolt holes and could with a little fettling do the trick!
