Hello, I have had my fit for two years now and its just about paid off. I'm building a custom turbo kit for it but only plan to run it at the strip. I want any idea about a good setup. I'm thinking the tr-1 shock spring setup with strong spring like they used in their time attack car. This way i can stiffen the back up all the way to improve my 0-60 foot times. But if anyone could think of something cheap please free to share.
