Nice job snagging a draggy pull. Just looking at the G-accel vs speed, at 100kph its looking pretty close to the previous cars accel. Not seeming to be a whole lot difference than what we already have up top but holds closer to 1g slightly longer.

The change from 9" to 11" on the same 275 A052 was pretty dramatic in how the car felt. Grip was up even though tires are getting pretty well aged. I'm almost down to no tread on the inside and ~2/32s on the outside. But still, they felt better than new being stretch rather than pinched. This...

Its just far more complicated than us looking at it as a simple mechanical system. Have you looked at undercar videos of how much a tire squirms on track? Its A LOT. There are several hard to explain reasons Ive come to this conclusion, but my best evidence is the tire wear on 9" wheel vs 11"...

Its about the angle that it moves. The tire/wheel is basically a trapezium so how the tire rolls will depend on the angles of the wall and the inside wall of a pinched tire will buckle inward and upward (relative to wheel center). A stretched tire will deflect but push down as the wall moves.

Tesla is absolutely the boogeyman car right now. But its just so misunderstood. People seem to have this idea that CG is underground, its makes 1000hp, and can pull 2gs from apex to the next entry. But its still an AWD car with 3 open diffs and and weighs over 4000lbs. It just happens to punch...

Not of too much help but first event of the year I had the car drop out of track mode on first AutoX run. Worried it might be related to the billet uprights and ABS sensors, I pulled the USB (Got idea from this thread), and ran again. Ive done ~75 more runs and it hasnt happened again with USB...

Yeah, sure I would take the TM3 over 2wd in the wet but the lack of LSD is pretty significant. I did a bunch of testing and I came to the conclusion you have to run more TC with wet because if you run it low the TC braking cuts it late but overly aggressively. But running it high it seemed to be...

I would say the M3P kinda sucks in the wet with its lack of LSD and weight. It does ok but I'd take something like an STU car over it any day.

Daaang, nice job getting to final round tho. I've been top qualifier twice and a cone away from a third, yet I've never made it out of the first round.

Finally got the 19x11s to stretch the 275s. The amount of pinch on the 9" wheels was pretty bad and A052s having such a floppy sideway just didn't do well at all with it. Tires are pretty worn now, especially on the inner half, but its only 70 runs and I'm pretty sure the wear is the inner wall...

Autocross has its only beastly heat issues when it comes to power and/or weight. We get things pretty hot (not track hot, but still hot) then park. So all that heat just keeps cooking. With the Evo, you'll see me spraying all kinds of things down after runs, even the sheetmetal in the engine...

Yep, stock pads and just a fresh bleed at Crows. Not sure if youve been down there but average speed is maybe 10-15mph faster than a typical Packwood course so dual driving we can bring in some heat. But good to know a pad change could help. In vegas we had quite a bit of issue with smoking...

Got them custom rainbow brakes. Apparently we made them hot at Crows :eek:

Welcome to the internet, you must be new here ;)

The 295/35/19s are 26.9" tall which is getting really on the tall side. I could tell a huge difference in corner exit power from my car to Dans car with shorter tires. For 19s the real options are A052 - 275 RE71rs - 275, 305 RT660 - 275 (30 or 35 sw), 305 CR-S - 275 Its a bit of a struggle...

I would run the 275 because the 285 is even taller at 26.9in.

Did anyone do any actual acceleration testing?

Fingers crossed the "only" 2.9 sec time is because they pushed the gearing to hold torque longer.

I'll take more power 40-80 before the fall off PLS. My butt feels the fall off over 40 now and on my back roads it just feels weak since corner exit is above the falloff point. I agree that speed to 100+ isnt all that necessary, but up to 80 should be fully reasonable.

I think 90% of that is pretty optimistic thinking 😅 I have a suspicion Elon is letting stock price drop holding back big news to get more shares for his bonus. Since he stated needing X percent of TSLA before he'd allow AI to get involved. But thats just me pontificating. Im guessing 2.7s...

Its been a couple years since I measured and I seem to recall getting 0.68 front but MPP or UP said 0.72 so I averaged it. Def not 0.6 up front though. I should have done a finer resolution measuring last time I had it apart but I didnt... 😅

From what I recall, they didn't subtract unsprung weight from mass part of the equation. But MR is in the 0.70-0.71 range up front. I measured the rear much more accurately though, 0.605 was the average over 6in.

Yep, this is what I would expect.

If it is, its not by much. All the kits for TM3s are super soft and even with my current spring rates (800/1200) theres quite a bit of roll. Thats only 2.1hz/2.2hz. And tires alone need 1.5-2deg on their own. My car also has more camber gain compared to stock upright TM3s. I havent done...

Some tires tolerate pinching better than others and usually it comes down to sidewall stiffness. Back in the day the A6 worked pinched but the A7 not as much. Similar thing with the Yokohama vs B-stone now. I went against my better judgement and put a 275 on my 9" wheel and its been pretty...

I bet theres some dragy results with dummy cars that employees have played with... Someone needs to start scouring for EV looking results ;)

I did a quick search and saw 506 and 510hp for a 2021. Dont know if either is exactly correct but seems about right.

Or wider is better. Its the 2nd order effect physics ignores cause it makes the math easier and is appropriate for most things.

Nurburgring numbers are 100% irrelevant to me. So much of lap time there is top end accel and top speed. And then with EVs they have to ship with eco tires for published range. Also, I keep seeing people talk about how quick others have gotten older M3P in 0-60 then comparing to potentially...

A 991.2 turbo + are so damn quick out of the box. My Evo makes similar peak power as the TM3 but 1100lbs lighter (ballasted). Launching its easier in TM3 buy orders of magnitude, but past about 10ft cause of traction the Evo just pulls past it. And a 991.2 turbo is faster. But thats 150k+ and...

If you care about range just swap on some Eco 235s and light 18" wheels then drive in chill mode.

🤦‍♂️. You missed half the topic.

I have the lucky distinction of building one of the XA benchmarks. So I can say with pretty strong certainty that at least the current M3P has a great chance of being competitive but not being an over dog.

CAM-C has a front engine RWD requirement. So its not necessarily because its an EV, its just the wrong platform. I already got confirmation directly from the board that EVs are intended to play in XA so we should be good for things past EVX. Hopefully the publish the clarification in this months...

They're SSB prototypes, only ones in existence right now. I have an idea of how 18s could fit, but will require a special post and both arms. 19s and 305s are the easy answer here. I think the power bump (if real) coupled all the right parts could make the TM3 the easiest and most reliable way...

Lol, since we're all children today... 😅 deez nuts.

Anyone thinking they'll want billet uprights, unfortunately 19s are necessary. The ball joint direction puts the nuts too low for an 18" wheel to clear. But yeah, stagger size might just be about putting extra power down for a more aggressive 0-60.

Doubt track has changed. Rear fits 275s with ease.

I cant imagine wasting processing power on something like that vs just setting a static map based on whatever parameters the designers chose. Especially with a damper, feedback loop would need to be something related to position which would be more sensors driving price. If anything, it would...

I would assume "release" would mean shipping release. Hopefully info is imminent and orders open shortly after.

We should all @Elon to request the standard on an M3P be a color. Fight the monotone!

2.9s as a base (didnt original M3P come as 3.5?) would be OK to me if they improved 60-120 more. What I would rather see, a real rear LSD.

Really depends on if the front uprights do well (sales-wise) and what they do with the new M3P. If its more of the same, I'll probably move on. If its mid 2s 0-60 and ~125mph trap then that becomes a lot more appealing. My M3P feeling slow compared to my Evo but 125mph trap would help with that.

Cant wait for details so I can stop hitting refresh a couple times a day.

Power isn't the issue of the M3P in AutoX terms. Without some help, its almost an issue of mo-power-mo-problems. IMO, a big issue/limitation is the power cut with steering angle Tesla has in the programming to tolerate the lack of rear LSD. I kind of want to find a way to intercept the...

Does anyone recall if the Model S with ludicrous mode also keep that accel mode while in track mode?

The Z06 is 66.3f and 66.1r with 275/345. Lotus Elise is 2" wider rear track width. S550 mustang is 2.5" wider rear track width. 991.2 911turbo is 0.5" wider rear track width and 70mm in tire split. We're just saying, total width split isn't all that important.

The 991.2 GT3 is 30mm wider in the rear. Track width isnt a limitation for stagger.

To my feel, the change is more like it retards the application rate of power to the other axle. But you still get to the same power eventually. And steering angle definitely has an effect on things as well. So its kind of unpredictable. But you can use it as a tool to adjust corner exit...

I tried to get maximum clearance on the uprights for tires but ran into a major issue with the upper control arm. At full compression the upper control arm angles far more than I expected limiting just how much I could do there. These pictures are +1 to +1.5 deg of camber from OEM (depending on...
