Averying's 2009 Platinum Graphite 370z Journal

Averying

Been slacking on posting anything here. Finally got to an SCCA autocross this year in Devens, MA. Video down below

Car felt good in the afternoon session once I turned up the dampers to ~2/3 stiff. I accidentally left them on almost full soft (which I use for street) in the morning session.

Need to be more confident getting on throttle earlier and staying on it later into the corner. Brakes didn’t feel as grabby on initial braking as I’d like, but I can definitely brake later into the corner and carry a bit more speed in.

Best time of 55.711 put me 48th/98. I’m happy with that result seeing as how competitive this New England region is and also the fact that the majority of folks ahead of me are on a sticky 200tw tire (RT660, A052, etc). My last run was a bit faster as well, but I hit a cone and botched the last corner. My goal is that more seat time and confidence should get me to top 1/3 of the field.

NER SCCA Autocross 10/30/22 (Video Below)
46/105 Raw time
47/105 Pax time

(Sorry for the long posts… this is also me keeping track of my progression)

Final Autox this year before winter hibernation for the Z. Ended up with a pretty nice day for end of October in the mid 60s.

My driving:
I felt more comfortable handling the car when it would get loose on entry or exit. I need to work on carrying speed through wider corners and keeping my eyes up to take a better line (which will help keep my speed up).

The car itself:
The car felt good last event when turning up the dampers. I turned them up 3 more clicks (front and rear) this time just to see and the car still felt good. I’m hoping I get to the point where I can tell when they’re set too stiff, and then I’ll back off a few clicks.
The car does feel a bit soft on these BC BR coilovers. Especially under braking there is more dive than I’d like. With 10k front 8k rear rates, they’re basically stock spring rates, and I doubt the dampers are much better than stock.
Due to the decreased # of runs and longer wait between runs at these SCCA events, I haven’t noticed the diff overheating and spinning the inside rear. I know a true LSD would be better though and is still on my future to-do list.

Finished 46/105, so I’m happy about coming in higher than 50% percentile in the field. Up to 44% percentile of the field. Goal for next year is to consistently get to top 1/3 of the event. Maybe then I’ll convince myself to go for a real diff and 200TW tires. For now I’ll try and chase down everyone on my current set up.
