Speak to Nick Caro (NJC11) ... he loves Worksop and his car goes around sweet. I can't help as I hate the place and avoid it like the plague.
A well set-up FS will feel really ballanced and thus like it's slow ... lap times will tell a different story though
I'm sure Nick will help but if not post up your set up and how you would like the car to feel different and I'll do my best to help you
