Great car to move into after the Supra! I drove one of these beasts out on a track in Vegas a couple years ago, and the GT3 is 100% one of those cars that a car enthusiast has to experience.
1. I believe they use the same leather. Up to you if you want to replace it. Depending on the options you want (LED lights, leather vs alcantara, carbon fiber), you may end up spending a good amount on a replacement.
2. A fair number of members do feel the factory alignment is poor. Probably...
The link I sent is also generic, not taking offsets and all into consideration, so it's more or less a rule of thumb.
You could maybe fit a 295 on the stock rear, but I'm not 100% so you should get more opinions. You may lose lateral stability and get crappy tread wear.
As for actual tire, I...
One site's min, ideal, and max tire widths for wheels. I believe OEM is 9" and 10", so you're looking at 265/285.

It's not always about the car. Some of it is about the community and Musk himself holding a "Tesla has been, is, and always will be flawless" attitude and treatment of people who offer negative feedback. I understand this isn't representative, but it's usually the extremes that shape the image...
Waze is crowdsourced, so it loses its effectiveness during off-peak driving hours and away from major motorways, and especially if you don't have data coverage.
I don't have a custom radar setup for $5k, but the Uniden R3 has saved my ass several times.
Tire Rack for purchasing, but it's been a pain in the ass to find Michelins in stock from tire dealers. I used TR's mobile installer for some all-season Contis for winter, but I'm using a local place that's in walking distance for PS4S installation on TS-5s since the mobile installer is booked...
Sounds like you're in a similar situation to me, but in Texas, where the weather is more conducive for running summers all year.
I'd maybe stick with 19" wheels and bump up the tire widths to 275/35/19 and 295/35/19 on Michelin PS4Ses or Super Sports. That way, you'll have a little bit more...
By bigger, it looks like you mean a bigger rim (using wheel = tire + rim), and wider refers to a wider tire?
I've heard people say that 275/35/19 can rub a bit in the front. Based on that, 285 should probably rub, and since tires for 20" rims will be bigger overall than the equivalent tire for...
I was running stocks last year, and the wheelspin was getting quite irritating. It started slipping up to 3rd with just a downpipe, and well into 3rd when I ran map2 on top of that. The increased contact patch is still gonna spin, but should reduce wheelspin a bit. Also, the car was slipping...
Likely no, max recommended width on a 10" rear wheel is 285. You need to aftermarket wheels for 295 and 305 in the back. PS4S should be the standard for daily driving in warmer weather. Usable when colder, but it won't grip as well, so don't drive it like you stole it when its cold (obviously...
