MASTER THREAD: Comprehensive Road-Course Modification Guide — Optimizing the 3 for the track

Yuck. I only run my aluminum rings with my track wheels, so a day or two at a time. To get them off I just shake the rotor back and forth to get a gap between the rotor and ring, then use a small screwdriver to pry them the rest of the way.

That’s interesting, I have much more trouble getting my 18” aero wheels off, despite the fact that they are mounted without rings, than my 19” track wheels with metal hub rings. The latter just come off super easily by hand.
@MasterC17 I think it makes sense to do the next step of this Guide...
This thread and some content on this forum (a lot of which is made by you, btw) are golden. But it's scattered, hard to find. And this thread first post is too big, too many options, but some areas not covered at all and I have a feeling you've changed your mind about many things already and have no edit rights even.
Most people wouldn't go through all posts anyway and the easier we're going to do content - the more people are going to actually do it. More manufacturers will start doing mods for Tesla, more people will go racing Tesla, more superchargers will appear near tracks, more knowledge will be developed and, eventually, Tesla might make Tesla Motorsports. You know, like Germans or GM.
Release Model 3 RS - "Buy it and go beat it on the track as much as you want". Hire MPP or UPP or whoever experienced in that from Porsche and ask them to manage the RS line, build a racing community. Make Tesla mono classes and events. Tesla Motorsports parts catalog, merch, and so on.
If Tesla won't start doing it soon we might start losing amateur racing together with the loss of ICE cars.
But somebody has to start it somewhere. You did already a great job. I'd like to help you to push it a bit further.
My suggestions are:
The racing part is only starting here, but it will be growing and we can help to speed it up. I know it's not a lot of builders here, but we can start with something in a more organized way. I'm sure moderators would support reasonable management of the racing corner. I don't see anyone better than you to moderate this subforum (and assign additional subforum moderators).

My suggestions are:
- Ask TMC owners to make the Racing subforum and put a few dedicated moderators there.
- Split the build threads from The Guide in a dedicated subforum. Make rules of build threads and adjust if necessary.
- Allow build threads to have forever edit rights on a first post so they can keep them updated.
- Make sticky threads about different key parts (even if there are no options available like radiator kits) for racing with running voting for available options with prices that fit racing needs.
- Make the Guide as a bullet point list in sequence of parts importance, mark ~money it costs for parts and labor, add links to parts sticky threads, explain in short what will happen otherwise, and describe what is important to have in specs.
- Make sure Guide is up to date based on real-life experience.
- Make a sticky thread of what and why is not recommended or was found to have issues.
- Make a sticky thread about build thread rules and endless voting on a first page for best build threads. Or, honestly, add some programming to make it more organized.

I completely agree that the information needs to be condensed and updated, and a lot has changed since I originally made the post. I would love for Tesla to seriously get into Motorsports, but I doubt that is a priority for them in the near future, so it is up to owners to do it.
The main goal of what I've been doing is to get more people into tracking EV's. Even if it isn't a Tesla (though I'll admit I have a soft spot), I think that this is the future of Motorsports and it's a great way to bring new people in, and old people back to the sport. The savings on consumables alone (pads, fuel, oil, etc) is massive. Once people realize that, I think they will be a lot more likely to get into a sport that has historically been economically unfeasible. Not that it is cheap, mind you, and I've put far more money into this effort that I ever could have imagined; but compared to a German ICE vehicle your saving significant amounts of money.
I actually just recently started working on something for the community. It was originally going to be focused on a single metric, but you are bringing great ideas to the table and I think I could expand on it. I will keep you guys in the loop. Considering we've been asking for a dedicated Track subforum for over a year and have not received it, I'm not entirely sure the TMC owners are very "into it". We're a small minority of owners right now, but I think that can change quickly.

Thanks so much! saved me a lot of time. I wish we could have had a tire/wheel section also

Track centric would definitly be a great idea, there's a lot of choices and also risks. So sharing learning from others is primordial.
Thanks for all your sharing!

Everyone thinks you need to mod the vehicle to make it track worthy. Honestly all you need is to bleed you brakes, change your brake pads and ensure you have good tires on it to have a lot of fun. If you want to go fast, buy tires first. I put camber arms on my car, I ended up going backward as the car is doing things that I don't want it to do. I don't blame the camber arm for setting me back, but track tuning is difficult, especially when you have the constrain that we do in EV cars.
I took a basically stock car and put down 1:41 at Laguna, 1:54 at Sonoma and 2:01 at Buttonwillow. I am sure better drivers can go faster, but that is still a very respectable time for a 4 door sedan on street tires.

I am right there with you this car is amazing, I put down a 1.47 last week at Laguna, and my fastest laps were when the car was power limiting and I wasn't trying too hard. I am still basically stock for a couple more weeks, but at 55k the stock suspension is certainly moving a bit more.
The only mods so far are UP pads, and Castrol SRF, along with the 275/35-18 Federal RSR street tires. That was my second outing to Laguna ever. These cars are really really fast out of the box, once you put proper brakes and shoes on them.
I just made an appointment for a couple weeks from now at the Driveway. I am going with MPP Sport Coilovers, upper camber arms, and lower control arm bushings.

13 pages to be thankful for!
What are other folks running for alignment settings? I wanted to have a setup where I could add in a couple degrees of negative camber at the track with the MPP upper control arms, but maybe its not really worth it?
Do others with the MPP control arms pull them out and put them in for track days? If you do adjust them, do you also adjust the toe?

Just get more experience, a few of us run below 44s. When I did 41 I was stock, I ran slower with the front camber arm and I ran even slower with lesser tires. You can run in the high 40s in reduced power mode, most cars cant even do that at full speed!
Camber changes have a big effect on toe angles. If you removed all the shims at the track and didn't adjust the tie rods your front toe would be at least -2.00* and you'll ruin your tires!
Exactly why I wanted to talk with the folks here about them. I had planned to run between about -2 and -3 on street vs track.
Was considering aligning it at about the -2 degree camber mark if that allowed me to not change the toe much for track days.
Trying to find a good balance between performance and how much setup I would need to do each track event for my daily driver.
With the stiffer suspension there should be less body roll. Are others With MPP sport coilovers and upper camber arms running the max camber the plates will allow?
