maybe you need to the camber/toe arms?

For ride height adjustment; no. The camber should be only marginally changed even at the maximum low setting. The toe can still be set to factory specs as there is quite a bit of adjustment in the stock eccentric in the rear.

It reads like they're not adjusted right?
Everything was installed correctly per Redwood discussion with the shop I used. The reason for the larger than desired gap (from my perspective) is the difference between the OEM tire (275/35-21) and the tire on there now (275/35-19) which results in a 2” decrease in overall diameter. If I want to decrease the gap, a 275/40-19 tires would increase the current overall diameter by 1”. Redwood mentioned that they have a few tricks go lower it even further, but after taking a hard look at ground clearance and wouldn’t want to go any lower.

I’ve had a chance to drive the car a bit more and am very happy with the overall feel. I haven’t been able to do any aggressive cornering yet. I can’t wait to get this to the track!

Oh I see you changed wheels but didn't maintain same circumference. I'd definitely change to a higher aspect ratio tire, don't know what that will do to the motors long term. But I suspect your acceleration should be killer with the smaller diameter tires?

Glad you happy with those dampers!

Yes, I changed to 19” wheels. I went with the same sidewall dimension not knowing any better. I am honestly not sure about any increase in acceleration as I don’t have any data other than the seat of my pants and that tells me I am hoping Tesla offers a power upgrade for MYP. 😂

I had the coilovers installed today. I had the dampers set at 16 all around and will make tweaks from there. I cannot really comment on difference in ride quality as I’ve only drove it from the shop to home (10 miles). I will say that was a bit surprised by the ride height as I had requested it be lowered as much as possible, according to the shop the rears are set as low as they can go, and I have more gap that I expected. Granted I am using 19” wheels vice 21”, but I was surprised nevertheless. I bought the performance sport and sent an email to Redwood asking if it is only the GT version which has max ride height adjustment.
Ride height has nothing to do with wheel size; 19, 20, 21 doesn't matter. The diameter of the tires is the virtually the same for all the factory wheel sizes delivered by Tesla.
Your installer should have been able to adjust ride height. The limit is more about the tie rods and resulting camber/toe.

Installer was able to adjust ride height no problem. The problem, which really isn’t one lol, is I was a bit surprised with the result gap between the top of the tire and fender based on seeing results of other lowered Model Ys. The difference is actually attributed to the fact that my overall diameter is now 2” less by going from a 275/35-21 tire to a 275/35-19.

yup......26.6 vs 28.6 inch will do that......

Once I wear these tires out I will go with a 275/40-19 which will increase current diameter by 1.1”. I currently have these set at 16 all around. I’ve done a little bit of spirited cornering and the handling is in fact night/day difference from MYP suspension. I have little to no body roll now. I don’t think there is any need to change stock sway bars at this point.

I wouldn't bother with sway bar changes for street use. The MY needs better dampers than the factory stock units, pure and simple. Other than that, the MY is a solid citizen.
I'd be looking to broker / trade out the tires you've got, though.

For reasons other than reducing the gap?
That much of a smaller dia. you are adding miles on your odo faster. You're also running the motor at a higher gear rate than intended, possibly increasing its wear rate. You're not off by a small margin like most, you're off by a huge margin man.

Thank you kindly for the heads-up. I will first contact Discount Tire to see if I can work out a deal on an exchange. I paid for the hazard certs on them, and will lose that money if I sell private sale.
