I am running the 275/35-18 RSR PRO on 18 x 9.5 ET30 with Stock Performance suspension. Totally cleared everywhere, even the corkscrew at Laguna. The only contact I had was my mud flaps.

I just had first session on them a few weeks ago. I really like them and the price is certainly right. ET35 should fit just as well, but will be close on the inner.

Here's some data and Tableau public graphic from my track recording (track mode data).
I'm just starting using Tableau Public at home for this so I'm by no mean a specialist ( I hate building report, KPIs and all that stuff :) )
In any case, technicaly you can add yor data and develop more sofisticated graphs.
There's 1 std graph showing lap 1 speed over time, pretty useless if you don't know the track/course.
There's graphic ( Geo Location) that shows the track, the with of the track is proportionnal to the data shown, there's 3 of them on the dashboard tab: speed, brake applied %, instantaneous energy used (Kw).
Again, right now it's just an exploration of what can be done. I think we could use the template for any course and you could just import the Tesla data and we'd get nice analysis...
Goos luck!

Glad you had a good time.

Wish I would have been able to charge at the track when I was at Mid Ohio. Would have made it much easier to deal with throughout the day.

I agree with the square setup. 275's fit easily front and rear.
I am going to mid-ohio tomorrow 5/6, any tips on setup or running?

I had a great track weekend for my initial outing after a Carbotech XP10 pad upgrade a couple weekends ago (with 245/45R20 RE-71Rs on the stock wheels.) Upgraded pads made a HUGE difference over stock. On stock brakes one really has to consciously avoid braking hard at the track. On the XP10s I was braking hard and late enough that several Porsche drivers stopped by commenting on how much braking ability the car had. Yes, the XP10s are noisy compared to stock on the street but I don't actually use the brakes enough on the street to make it worth a pad swap and think it's a decent brake compromise between track and street.

Tip: Avoid tire rollover while at the track on the stock alignment by keeping the cold pressures up within a few psi of factory (e.g. 40-42psi) Upgrading the front and rear upper control arms needs to be on the short list of upgrades to save money on tire wear (it's certainly on my list)

Tip #2: The car handles really really well in most situations. I think the exception is it feels pretty unsettled at high speed (say 100+ mph) under hard braking / trail braking with any back and forth wag of steering input. In such situations the back end wobbles and feels like it could get loose and come around. Hopefully I'm explaining it well enough to make sense. Just focus on driving smoothly and you'll avoid this oddity. (I feel it's more of an intermediate driver problem situation and think the rear traction arm upgrade is probably aimed at this??? Perhaps someone can comment.)

I feel that every step of stiffer suspension, lowering, front and rear uniball bearings, higher friction front brake pads and rear wing completely removed for me that effect.
