Running full GS allowances minus catback. High flow air filter, Tires are 225/40/18 Rivals, eibach rear bar on the stiff setting and koni yellows set 1.5 turns from soft in back and one turn from soft in front. It is very balanced and composed with almost neutral handling. Changing the front shocks to any firmer induces more understeer. I could use more rubber, but am very competitive with these settings.
