I wouldn't pay new prices for 1.5 year old tires. It depends how much she drives though. If the tires are going to wear out in 4 years anyways, it doesn't matter. If she doesn't drive much, and you'll end up replacing them due to old age, then you just gave away 1.5 years of tire life.

As others noted, even in track mode, the NPP valves close in certain conditions. I played around with pulling the fuse but eventually got the Mild2Wild so I had the option to keep it quiet. Happy I got it. Ended up getting another one for someone else, but theirs is a 2014 and it doesn't work...
I wouldn't worry about drying your rotors, but I would suggest not parking your car with hot brakes and leaving it for an extended period of time. If you need to park with hot pads, make sure to roll it periodically. What is generally referred to as 'warped rotors' or similar is actually brake...
TFX is typically the go-to for moving high-end vehicles. Not cheap though. One of the big transport companies has a enclosed vehicle division as well - I believe it's Mackie. When I got my C7 shipped from Calgary to Ontario I ultimately went with TFX, but was considering Mackie - and I found...
Cut off an inch of your long allan key and then just put a wrench on it. Alternatively, I'll sell you my special short allen key for 2005 Corvette diff fluid change for $20, haha
I'd say I've done a fair bit of brake fluid research over the years, and I've never heard that DOT4 absorbs water quicker than DOT3. From what I've read, there is no performance downside to using DOT4 instead of DOT3. The two are generally interchangeable as well, unless you're on the fringes...
Z51 is certainly track capable. I don't hold a crystal ball for future values, but as you seem to know, C7 values have held up well so far. Z51's don't have the wheel issue that the Grand Sports and Z06's have.
Might be worth waiting a bit longer to make the plunge. I was planning on...
Speed Therapy, Ontario Time Attack, OMSC, and SPDA put on the best events.
If you've never done any track events, I highly recommend starting with a driving school.
I'd be interested to see those. My understanding is none of the aluminum hooks can actually be used for towing. Would want to look into that aluminum hook on a steel receiver as well.
