Haha, I have been asked this before and Sasha didn't think it would be possible with the PB in the location it is installed!
With low/off regen, trail brake is easier and more intuitive, because Tesla's regenerative braking is not integrated into the brakes.

My 370x34 front rotors are pretty worn and will probably need replacing.
Would UP’s 394mm kit be a worthwhile upgrade, compared to, say aggressive ducting?
(Note: I am still on stock rear M3P brakes with aftermarket pads).

What kind of times were model 3's running there?Not related but a Plaid caught his brake ducts hoses on fire this weekend at laguna seca

315 Nexen. Slippery on cold wet track! Felt pretty good when they warmed up a little. I placed 17/63 in Optima challenge7th in both speedstop and Autocross.
I’ve got some brake ducts and hoses but am thinking I should use them to duct to the UP drive unit filters vs brakes. But I’m still only running small tesla calipers + MPP rotors.
Carbon one gets soft pedal as well. I don't know if any ducting really works on a street drivable model 3. I plan to do water injection this summer. Already got all the parts.

Interesting. I don’t think I’d ever heard of water injection on brakes! How do you avoid warping or, just as importantly, inadvertently dropping water onto the track? Fine mist only at high speeds?
I did a 1:42.55 should be running 1:39 probably on the nexen I have I think. It hailed the night before and our Saturday evening practice was canceled. Hella slippery in the AM session! I did. 1:50. It was my Second track session & only really did 3 wet & 2 dryer laps. Drive more conservative than I do in hill climbs
Jon-1:47 /1:40.5
Brandon in plaid- 1:47/ 1:37.01
Jordan- 1:46/ 1:38.76
Koda- 1:58/ 1:42.2
Some cool cars to race with! GT3 is probably my favorite

You just need to ‘dance’ on the throttle if you get any reduction. But ya, you can’t feather as you say.
I'm going to use cooling mist jets and 200psi compact pump. Water on the track is not a concern, since a/c throws tons of it there anyway. Rotors can't really warp from that amount of water - the amount of heat from the high speed braking far heavier stress than any water mist. Also it instantly makes vapor layer. It will be difficult to keep water close enough to rotors to evaporate rather than get blown away with the air. But it's already used approach in trucks racing.
Interesting to watch your lap compared to mine. I assume you run more tire than I do as your min speeds in the slow corners is faster than mine, but I get you on some of the faster.

My fastest was a 1:36.6
Tony you are a beast on those 255's! Ran a 1:41.753 at 220kW power limit.
Gotta admit though, it was a close Qualifying!
@subieworx thats pretty awesome! I’m super uncomfortable on braking points and entry speeds on the track. It’s my second time, (first was 2020 Corsa) I have way more hill climb driving time!! Also first time trying the Nexen 315s and they definitely did not like the cold. After the wet laps in the morning I was a bit cautious in the evening…also started this one on 40/60 split

Is that really the best steering technique? I’ve always shifted my hand position in Autocross & was never taught not to. Or just never taught. I want to try & keep a solid grip but I don’t like having arms crossover (in theory anyway)

I stick to 9&3 unless I really have to wrap the car around a tight hairpin!
(Don’t mind the overly high stability assist… was experimenting and found it really annoying… Also, yes the music is a bit over the top but I am who I am… )
