Looking for help for SSR7 tuning

[Firehound427]

Hey there. I've decided I want to start my own tuning garage, specializing in tuning for Wangan (Highway) racing, which means tuning for Special Stage Route 7. Thing is though, I do not have a clue about tuning. I have a bit of knowledge of tuning the transmission, and there is the option to use Voodovaj's Suspension Wizard, but I was hoping if someone out there was kind enough to help me with any advice/hints/tips for tuning cars for SSR7?
