Never ask that question on this forum again.
If the car has shocks that work, and you will drive it hard enough to use full travel, it does not matter what the ride height is when it is (hard) parked. You will eventually bottom it out and whatever is going to rub, will rub.

When we check for wheel tire clearance we put the car together without the springs. We can then cycle the suspension through its full bump travel crushing the bump stops, check full steering lock and see if anything is touching. We then put the springs back in, align it and then basically jump the car while turning at Max G. This flexes control arms and other suspension pieces while deflecting the bushings enough to move a tire that was maybe just close on the rack with no springs into hard contact with something when it's pounded over a race track kerb.
Many of the wheels that we offer with the standard tire sizes that go with them are what we call Race Fitments. That means that under normal use on track they don't rub anywhere but they might rub slightly at full lock when you're parking the car or maybe turning into a steep driveway.

Not exactly. Some wheel/tire combinations will not rub regardless of what you do.

I went back to double check what tires I was running that weekend and those are indeed 245 RC1's on 15x9" wheels. Advanti S1's.

I went to another local autox event and I'm really in LOVE with these tires.
They are extremely easy to predict at limits.
I actually did pretty well on today's event thanks to the new Maxxis 245s/15x10 6UL setup

Looks hooked up.
I have to say that is an incredibly dangerous course. Whoever designed that course does not understand vehicle Dynamics or the way a car will Spin and the way the driver will correct if there's an error. Two separate spots where a basic spin would have taken out bystanders. Yikes.

Yeah course layout was pretty bad/dangerous compared to the local region SCCA.
I think I was about 2 seconds faster than the fastest Porsche on this event.
But to be fair, this region PCA doesn't seem very active on autox because I'm not anywhere near the fastest in my local region SCCA.

Did an autocross this weekend past with the VR-1's on Advanti 15x9's. These tires are freakin' AWESOME!
Tons of grip. Handled transitions better than I could. Easy to predict at breakaway. I under-drove them most of the day 'cause I wasn't used to a tire like this. I was 3.5 seconds off of FTD for the stock classes and I could have shaved off another 2 sec if I didn't drive like a pu**y. These tires are AMAZING!
I can't wait for the next event and start driving like a MAN!!

Did ~6 sessions on them at SMMR this weekend. 245/40 VR-1 on 15x10 6UL, 600/350 MSM Bilsteins, full-weight NB2, 200whp. Initial impressions are all thumbs up. They are very forgiving, similar to an RC-1 in that respect. They tolerate lots and lots of slip angle, and breakaway is very progressive. Lots of audible feedback when you exceed the limit. Optimal pressure seems to be 1-2psi higher than a 225/15x9 RC-1 combo. Wear is minimal, far better than the RE71R/RivalS/V720 group. I did not get a chance to do a consistent A-B test with the 225 Rival S since I was making other tweaks to the car and picking up big chunks of time in each session.
