OMG speed cost ! Now I have a clue in setting up the car and I have confident tat the next time I go to this track, I should be able to hit the 2 minute mark.
Thanks for reading !

I instruct out there and I only got a chance to talk with you briefly but great job and great lines! Your data should tell you where you can find time. I'm assuming you have data due to the overlays on your video. Considering the length of the straight the most important corners on that track are: T15, then T3, then T8a.
T14 and T15 are really hard on the tires as is T2. The lateral loads in 14 and 2 are extensive on the tires and the camber in 15 eats them away.
I did a 30 minute race on lightly used Hoosier R6's and by the end of the race I corded the left front all the way around (FWD). And this is on a car where I have the camber dialed in to maximize the contact patch. It's just an abrasive surface but that will change as it ages. Since this is a relatively new racing surface it is harder on tires than old racing surfaces like Pacific Raceways or Mission Raceways.
It's neat to see that with some slight power mods, alignment and suspension change and some track tires there is
that much time to be gained. I look forward to you hitting the 2:00 minute mark. In fact, I see a 1:57 in your future.
I see you leaving time on the table in these areas:
1: Alignment. Camber and toe. The mac struts don't have crap for dynamic camber so you really have to dial in lots of static camber (but you clearly already know this)
2: Tire pressure. The R888's are a bit more difficult tire to "dial in" compared to the their RA1 brethren but your data will determine their ideal operating temp.
3: Some modifications to driving the track, but I don't see lots to be gained here, you're doing great. (Modify T15 a bit, LFB down corkscrew into T14, entry into the carousel.)
4a: Getting to be WOT in the sections you need to be. See 4b
4b: From uphill right hand between T2-T3 to entry of T6, the carousel, and I can't tell form the video if you are but it looks like you lift in between 3 and 4 and you could roll onto the throttle earlier before 3. From top of T6 to braking for 8a you should be at WOT. I see your car washing out in the front exiting the Carousel. If you can get the front to grip better you can probably brake slightly less for 8a and carry more speed in which would allow you to get away with not using 2nd gear. But due to the powerband in this car, if you're rolling onto throttle below 5k rpms you're probably leaving time on the table.
A tire pyrometer and some camber/toe adjustment tools for quick and accurate changes at the track will do oodles of good. It seems like you might be trying to compensate for the lack of grip in the front with the toe out in the rear. Is this so? If so you might want to soften the front (and add camber) with either a smaller bar, softer setting on shock or even a slightly softer springs up front and then toe-in the rear a bit to make it more stable as you add front end grip.
shameless plug:
Ridge Racing School is still planning on doing the "Black Friday" track day for the day after Thanksgiving. (friday nov. 23rd). It will most likely be wet but it will definitely be fun.
