So a bit of a quick followup here after the event.
We did really well! In the morning, we started the first two stages on the wrong tire pressures (35 PSI in rally tires, felt like I was driving on hockey pucks). I still managed to get within 6 seconds of the leader on the first stage, and a 4th place time on stage 2, faster than the current champion. Lowered tire pressures, then on stage 3 put down a 3rd place time, faster than a Rocket Rally-built car and very close to the pace of the top times. Not bad for a little 2.5 N/A!
After seeing those results, I just wanted to finish the rally, so we put on the studded tires to have more grip in braking zones and mid-corner. Our times suffered a bit, but we still managed to secure a 7th place overall finish, and a 2nd place in class, production 4wd, behind an Evo8.
I'll be editing and uploading videos soon, will post those and more pics shortly!
