@SEvans I did the same, you'll feel a big difference in the ride with more rubber under you. I took the OT wheels/tires with me when we picked mine up and asked the dealer to put them on while I did the paperwork.
Wow, I never cared much about adding mudguards but at $17/each with the 25% off I'm thinking about it. I think the Lexus rears are around $50/ea if I recall correctly.
Welcome! When I was waiting for mine I found the search function in the top right corner of this page really helpful. There are tons of threads going back to 2024 full of great suggestions for accessories, wheels & tires, whatever you need. As a result I had all my decisions made and add ons...

My brakes don't squeal often, only after wet weather + being parked overnight. Had my 10k service completed at around 9k last week. I asked them to check the brakes due to the TSB being issued. They ordered the brakes and said they would replace them as soon as they come in. No push back at all.
