Fastest Lap Onboard
Summary
The data from last round said that my car was really touchy on the throttle. It wasn't really "oversteery" per-se, just unable to put down power. So in addition to changing my driving style, I tried using a different differential fluid - Redline 75w90NS instead of the Motul Gear 300 I had previously. It was pretty old anyway...
I also reduced rear pressure. ~36psi front and ~33psi rear hot.
I was pleasantly suprised by how much more tractable the car was. Laguna is a very exit-heavy track so I wouldn't have been able to do well if my exits didn't get a whole lot better.
I was able to end the day just 3 tenths off Ivan, and set a PB by a massive 4 tenths despite these SX2s being on their 7th track day.
