Where abouts do you live dude? Your up Newcastle way arent you?
I used to know a suspension guy that set up race cars in Castle hill, but that was about 10 years ago. Other than that, you could go to the Whiteline workshop in Minto, or their distributors in Gladesville (cant remember what they are called. RPM?). Dont know how much they charge though. If you ring Whiteline, they will probably have a list of reccomended workshops in your area.
