Just keep practicing, you'll get there. Having someone who knows the track well drive with you can give you a big head start. Also, using a sim to become more familiar helps too.

Guys, I have a question regarding setup on my M3P. My local track has 14 right handers and 9 left handers. Does it make sense to have more camber on the left tire than right tires? e.g. -3 on left and -2 on the right.
If it helps with discussion, the end speed at the end of turn 1 for M3P is about 120 mph.

You are over thinking it. Drive some laps and get some feedbacks instead of paper racing it
Full 20 minute session complete without major issues other than traffic, brakes, some thermal cut.

Here is my first run up the hill (& only without music)
& this is my 3rd run which was only 2 seconds faster!
See if I can do a little better today

My second overall win - King of the Hill 
Larison Rock
2/3 so far ...next up Mary Hill
I'm #15 overall in 33 years. The top 100s time was a snowmobile powered 600 lb car!!!
pretty consistent but I never put everything together correctly 
...I said my goal was a 107-110 which was a wild goal I thought, so I'm pleased...
maybe I'll try it once more? I know I can do a 108-9 if I don't over push some stuff and just blaze through other parts w/ a deathwish! 106 w/ 315 A7 I think
this is the Subi that ran a 113 & took 2nd

Think this was the only run I put my parking lights on for coming out of the ‘endless corner’ 9 into speed traps , I hit 86, top may have been en 89? I seem to be a few under the faster cars always in the highest speed areas. Pulling out of corners is the biggest advantage

Hit Palmer Motorsports Park yesterday. Fast Lap was a 1:45.4. Here's some video chasing a White GTR.
I really want to go to Palmer! How did you manage charging - did you show up with ~100%, drive your sessions then supercharge after the day?

Our tracks and hill climbs are often a bit shorter than yours, but still a lot of fun, so I though you might like to see a couple of clips.
This is Brands Hatch in England. It's only a 1.2 mile track but perfect for the M3P to embarress some of the more track-focussed ICE cars. Here's a BMW M3 Clubsport which didn't want to let me past...
Shelsley Walsh is the oldest motorsport venue in the world still using its original course. It's been going since 1905 and I'm entering my M3P in their summer meeting at the end of July. This will be the one of the only competitive events this year in the UK that EVs can enter because the safety rules are just too tough for most venues and clubs. Here's me at a practise day a few weeks ago.

They have a single NEMA 14-50 Outlet. I charged between every session, starting the next session with about 10% less than the previous each time. Would run about 10 minute sessions.
Thanks for the sticky thread!

Forgot to add that all parts were installed by The Driveway in San Jose. Car is corner balanced with me sitting in the drivers seat and experimented with many alignments to find the perfect balance between high speed stability and low speed rotation.

Great work, car is fast! How do the Nexen's compare to the Nankang's?
I think the Nankang AR1 is better for longer run time ( more than 20 mins) as they don't get greasy and do not have accelerated wear when you are pushing them pass the limit. However, they do seem to get heat cycled out before all the treads are gone and grip suffers. They also have narrower peak grip than the Nexen. On my car, I get a slight understeer bias.
Nexen Sur4g is the opposite, faster tread wear but don't get heat cycled out. Amazing sticker performance and then drops 0.5s and is consistent until treads are gone. Not endurance tire but I can easily run full 20 mins session with them and don't feel much fall off throughout the session (assuming temp is not blistering hot). It will tolerate more slip angle than AR1 and has broad peak grip range but will wear faster if you push it past optimal slip. On my car, this tire is very balanced front to rear.
I don't think I'll buy another set of AR1 since I get the same or better lap time out of Nexen while costing nearly half the price. AR1 is more geared toward longer runs and with our car, that's simply not possible.
(no sway bars?)
...and, what alignment do you like?
I put my car on corner scales and have my alignment since adding suspension and lowering, car was pretty pretty well balanced as it was set.
I only really get to do Hill climbs and auto X so not really the same high speeds as tracks...tighter and bumpier with more turns
