Wish we had talked to you. Rex was stuck at home, and the kid and I are more on the introverted side.
I'm glad you're thinking of jumping in to STF - it will be fun to see what the car can do in good hands!
Since we've never done any mods even within H-Stock allowances, I'd like to start there and see how it goes. I've already started the season in stock street tire and have a good rivalry with a DS Cooper S in our local club. Hopefully, we can take a few steps that will be legal in HS and compatible with a future ST upgrade.
All input seems to indicate shocks and a rear sway are the top priority. [I don't think my '02 has a winter package to disable.]
What all have you done to yours within HS?
