    Ok lookin good. Leave it in 4th for turn 5 until you can figure out how to get through 5 closer to the limit (entirely possible 4th will be the right gear) Everything else looks decent enough.

    Was having trouble joining the gopro footage together of session 4 but here is footage of 2 hot laps in the 4th session. 1st lap is a 1:35.3 and 2nd is 1:35.9.

    Except no clitch kick in 9 and still loose in there.

    OP, do you have a whole session you could post?
    I can upload a video of the last session on youtube tonight since thats the only session where I was able to consistently get laps in back to back without traffic.

    I was just going by what flyin miata recommend with these spring rates. They suggested oem 12mm rear sway bar or no bar. Im on 10k/8k rates with unknown valving. Ill throw on a rear bar to try out at the net event.
    May I suggest starting at full soft in the rear when you put the bar on.

    your heel and toe..... ummm, not very good.... you are upsetting the car every time you down shift.
    Yea, it is very bad. I practice on the streets when I daily drive but I cant translate it to the track. One of the things I will be improving on this year.

    That's... different. Could it be a push problem? Or maybe a shock valving issue? Or getting into the stops too hard?

    Put another way, it seems like the limits are way low on entry, then you're suddenly way under the limit.

    What shocks are you on? Looks like you have a fair amount of front sway...


    Or maybe it's just tires that are really wide.
    Im on Feal coilovers that I bought used so I dont know how the valving is. I have a bigger front bar and running no rear sway bar. A 3 inch front splitter and a blackbird fabworx lexan spoiler. Also running 245 width tires. Also a .25 inch higher rear rake at the pinch weld. Could it be I am scrubbing to much speed with oversteer on corner entry?

    T1: Killer, taking it nice and deep. I don't know how/if you can go any deeper. There's only increments left to gain here.
    T2: Take it in deeper, bigger lift, but not all the way off, then gradually back to full power in one motion. Let it track out at the top of T2. You don't need to keep it tight to the right to hit a second apex at the corner worker station. Looks really good though.
    T3: Turning in a wee bit too early. That's why you had to counter steer on entry and mid corner.
    T4: Ya man.
    T5: What Rob said, in baby steps. Use the end of the red/white curbing on the right as a peripheral-vision marker to initiate turn-in to the left. You turn in a little late, and this is probably the only turn on any racetrack on earth where that isn't advised. Good luck.
    T6-7: I do a straight line from the outside of T6 to the inside of T8. Shortens the track "un poquito."
    T8: Giggety.
    T9: I think you can go back to full throttle earlier if you stay 2/3 left a bit longer. Nice, deep approach and fast entry , but maybe a little too tight throughout. Ballsy, though. Well done.
    Thanks for the tip! The next Big Willow event is in oct for me so Ill review this thread again before I go back.

    I had that in mind the whole day actually but I believe I approached it wrong. I should have focus more on mid and exit than corner entry alone. Looking back at it now, I prolly dont have to down shift to third and just stay in 4th all the way through.
