Hey Everyone - having just installed my rack on my Model Y, I thought I would chime in here.
First, for those who don't know, this rack is made by Yakima. I was skeptical of buying the Tesla rack at first b/c it looked fragile, and like it was avoiding the most basic design principles for bearing load by being curved at the transition to the towers. Now that I've handled it, I feel much better that this is a legitimate cargo rack, designed engineers experienced with this product class. It is surprisingly heavy given how slight it appears, and it is very solid. Now that I know it's Yakima, the price doesn't bother me b/c it's on par with other legit rack systems.
Second, I wanted to comment that for me, the initial install took between 60 and 90 minutes. Others here are predicting they can do it in 10 - I'm a bit skeptical of that, I think 15 is more realistic if everything goes perfectly, and up to 20 otherwise. The main sticking points are lifting up the rubber gasket between the glass and the metal, and then slipping the metal L-hook/bolt bracket under the gasket and glass into its receiver. This process is tricky./ For me, every time the rubber gasket ended up pinched and folded under the glass with a big gap leading forward and back from the bracket. I could have just left it that way, and that probably would have saved 5 mins all the way around. And I could have entirely skipped trying to even lift it up in the first place, and just shoved the bracket under it and let it be pinched in there. With both of those optimizations, then I can see 10 mins.
My concern is that if the gasket isn't laying as flush as possible, a) it'll cause a whistle at highway speeds - although the tower feet may be flush enough that this doesn't happen, an b) that it will permanently deform or even tear the gasket, and then that will cause whistling at speed even when the rack is not installed, and may reduce resale value of the car since so many people are uppity about wind noise in such a quiet car.
It is worth noting that my roof is not installed perfectly symmetrically, so one of the four brackets fits very tightly. There is zero play between it and the glass, leaving me concerned that it could cause a crack once I put actual load up there and then drive, particularly on a bumpy road.
- that way, you'll have a use for your rack!
