So glad you just said my frustration these days... hope that is true for me too! Having no nannies, i was slower and experienced bunch of spins and eating dirt. BTW, BRP dirt is soft but it is SO hard to clean out of ur car

I feel like my body kinda gets what the car is doing now (slowly and still trying to get a sense of it) and I am learning how to react to them. Before, my SC light would go off and would save my ass =) But it is SO MUCH more rewarding when driven smooth and settling the car VS nannies on and throwing the damn car in anger-throttling and blaming your tires/tire pressure/ uhhh brake pads/ .

Completely agree with your second paragraph. My philosophy is from some F1 driver, I want to say a Fin but pretty sure it wasn't Kimi maybe Mika? Anyway, the quickest way to find the limit is to exceed it. So, the track is the perfect environment to do exactly that. The worst that can happen is you go off and have a talking to on pit lane. The tracks here are no where as risky as the Green Hell, grow a pair and do it!! Just do it smartly.

Is this most peoples experience? Once DSC off they slow down and take awhile to build back up and times to drop? Maybe I am different but I slowed to be cautious the first few laps but within one session had dropped 2 seconds off my best time.

Although it was with Porsche vehicles, each time I turned it off I was several secs faster, with GT3 that difference was over 4 secs at VIR.

Interesting. I found the PSM non intrusive on my C2S (took both M3 and 911 this past weekend). Clocked a 2:12.4 on a completely stock with PS2 911. I tried with traction off and realized I was adjusting the throttle quite a bit and this solved the issue hence faster lap times.

On the M3, even with the Euro MDM its WAY too intrusive. MUCH faster without it on.

You may be a smoother driver than I am I don't recall how a C2S behaved on the track, while driving a 981.1 Cayman, I left PSM on mostly, I was turning low 2:20s at VIR and 1:28s at Summit, nothing special. Once I turned PSM off I went 2:18 and 2:26 respectively. Given that the CS is low powered, the difference is normal I imagine. With the GT3 it was more dramatic, 2:18 with all on vs. 2:10 with TC only, and more importantly, that was repeatable times, not one-offs. At Summit I went from 1:26s to 1:22s. All stock car, no modifications; the GT3 certainly needs double the spring on the front and can do mid to high 1:20s at Summit I think, the C2S may be similar.

'08 E92 M3 6-Speed MT

Track/Course: Buttonwillow 13CW
Best Lap Time: 2:06.10
Brake: Stock rotor and caliper with PFC-01 Pads and Goodridge SS line.
Tires (Size & Model): 265/18/35 Hankook RS3 on Apex ARC-8 18x10"
Suspension: Stock (no-edc, no-zcp pack).
Traction Control: off
Other Mods: None

Track/Course: Buttonwillow 13CW
Best Lap Time: 2:02.35
Brake: Stoptech ST BBK (60F/40R) with Stoptech Street Pads

Somehow my laptime gets 1-2 seconds quicker when i'm running the last day on RS3 (6-7th track days on tire). I know it sounds odd, but it happened almost every time when i am about to change tires (I've had three sets of RS3 so far). Anyone else having this weird situation?

Just did a track weekend at Road America. Below is a video of my best session, second lap is the faster one. I had a few laps in other sessions that should have been better but blocked by traffic. Overall i'm pretty happy since its my second track day in two years. With a little more confidence with my brakes (cracked the rotors second session of the morning but still tracked, I think i'm capable of 2:34's.

Car:2003 BMW M3
Track:Road America
Best Lap Time:2:36.66
Brakes:Brembo 6 pot w/ Hawk DTC70
Suspension:Motion control 2-way

Thank you!. I was looking for you al weekend, thought you would have been there for sure. If you decided to do Road America later in the year with MVP or BMWCCA, let me know. We had 4 of us that weekend, so it was a lot of fun.

Get some sticky tires and you have those 2:36's

Went to SpeedVentures on Sunday. Nice day, although it got fairly warm in the afternoon. The new pavement really seems to be curing and getting grippier because I keep getting faster. I also think the "lower" berms also makes things faster. Anyway, I set new personal bests with Euro-MDM on and DSC-off. I think it will possible to get to 1:54 by cleaning things up a bit.

E90 M3--Euro-MDM on.
Track/course: Buttonwillow 13CW
Best Lap Time: 1:55.19 (transponder) (I ran several laps at 1:55)
Brakes: AP Racing - Cobalt Friction XR2 front/XR3 rear
Tires: Hankook TD - 295/30/18 square on Apex Arc-8 10.5" (2 day-old tires)
Suspension: JRZ RS Pro
Other mods: VF620, Akrapovic X-Pipe with stock exhaust, RD Sport front sway bar, (full interior and no aero parts)

E90 M3--DSC-off

Nice runs dogbone, I'm anxious to get out to BW as I haven't been there since May. The surface looks like it's cured nicely and some good rubber has been laid down. I also like how they have flatten a lot of the berms so you can actually ride on them (including going into the front straight). Have you found yourself riding the berms more and before? My personal best was 1:57.7 CW13 back in early Feb with NT01/RA1s so I'm curious what times I'll run in mid-Nov when I head back with PCA SD.

Thanks! Yeah, in general, it's easier to get on the berms because they're 3 inches "shorter" than they were before, but I still don't run with super-stiff suspension. It takes a bit of running the track to adjust how you're approaching it----from both a line standpoint and a traction standpoint. It is different out there than it used to be. You'll get used to it pretty quick. Most of the people I talk to are 1-2 faster on the new pavement now. My fastest on the old pavement was 1:57.5. My current PB is 2.4 secs faster. I truly believe that for me, dropping into the 54's is attainable with some cleaner driving. I'm only .19 away.

Your car is a monster. That thing can surely fly around that track. If you didn't get into the low 50's, I would find that surprising. Are you running a grippier tire setup now?

I wonder if stiffening up the suspension will help you get into the 54s since they got rid of the potholes and dips. The rear RA1s that I run are 7 year old tires that get greasy quicker than the newer front NT01s so my back starts sliding around after 15 minutes. I'd like to get into the 55s with the NT01s/RA1s and maybe 1:53-1:54 with fresh R6s or BFG R1s. I think your car is probably capable of running 51-52s with all the power.

I'm gonna run my street tires (RE-11s), NT01s/RA1s, and new R6s at Chuckwalla this weekend to get an idea of what the delta is between each of them is and might do the same at Buttonwillow in mid-Nov with PCA SD. I think with someone like Billy going 10/10th on R6s or slicks in cool weather the car might do a 1:50 or so. To get into the high 40s the car would have to go on a diet.

Not knowing your car can't say for sure but comparing nt01s with fresh set of r6 should be an easy 2-3 seconds and adding in new surface another 1-2, Without doing anything different. Then another 1-2 on driver mod. There is always time to be had.

Yeah, USCTrojanMan29 is in a saaawwweeeeet GT3RS with quite a few nice mods. The car is very very capable. I agree----fresh quality tires like R6 and new pavement should be worth 5 seconds alone. Plus, he has another half year of track driving experience. That should equal low 50's in my estimation. Now if he still shows up with lower grip tires, then perhaps the difference won't be as dramatic.

Great lap @ 1:55.1 dogbone.
You are a skip away from 1:54 and a hundred miles away from the 2:15 just 2 years ago.
Great improvement!!

I'm familiar with off-ramp, but in which configuration is on-ramp?
