Suspension Height - P3D vs. P3D+ vs. RWD

    I received my P3D without performance package at the end of July. When parked next to RWD cars at the delivery center, it was pretty obvious that my car was lowered slightly (when I ordered it, the performance upgrade package did not list lowered suspension as an upgrade). I'd be curious what other people's ride height measurements are, especially the P3D+. I measured from the top of the fender/wheel well to the ground as well as to the center of the cap (to eliminate differences in tire diameter). Here's what I got - note I'm including all 4 wheels b/c there's a 1/4" variation; sad!

    RF (right front): 15 3/4" to center of cap; 28 1/4" to ground
    LF: 15 5/8" to center of cap; 28" to ground
    RR: 15 3/4" to center of cap; 28 1/4" to ground
    LR: 15 7/8" to center of cap; 28 3/8" to ground

    (example picture attached for how I measured to the cap) rideheight measure.jpg

    Dude, you measured your car, but not the RWD model next to it as a control? And you took a picture of a 1970s Jeep for illustration? I know this is not your day job. You should probably keep it that way :)

    Err... I measured my car just now, two weeks after receiving it. I didn't have a tape measure at the delivery center when I picked it up. And I used the jeep illustration b/c it was the first clear diagram I could pull off google images without having to make my own.

    That all said - you're still right - I make no claim to be good at this :)!

    I liked the Jeep illustration as it's amplified.

    Plus he was clearly crowd sourcing the work.

    Yeah, you really screwed up.

    Everyone knows you go to delivery with a tape measure, and a pair of calipers to measure panel gaps.

    :p

    If it seems like a lot to measure - just do a couple wheels from the center of the cap to the top of the wheel fender. No need for 8 measurements.

    What are we supposed to do?

    Put bolts on them ourselves?
    Agonize over them?
    Try to forget that they're there?

    I took my car to the service center today (for an unrelated issue) and they confirmed that the bolts are totally normal - they were necessary for mounting when the car was getting built I believe.

    I'm sorry, but that can't possibly be the case. The panels that line up perfectly with these bolts, or holes missing hardware, are loose. I'll definitely be looking to put some hardware on/in them.

    to my eye, if i'm looking at the same thing, those are push-pin type fasteners for the liner... ? or could be - either way don't seem fatal to be missing still...

    Just got my P3D+ and I think they installed the wrong spring on the back of the car.

    tire pressure 42psi, very small incline in my garage.

    Right Front: 28 1/8" to ground
    Left Front: 28 1/8" to ground
    Right Rear: 28 3/4" to ground
    Left Rear: 28 3/4" to ground

    the front matches SupersonicP3D but the rear is way off. Could someone with P3D+ please provide measurement from wheel well to the ground? I might need some data to take with me to the SC.

    thanks in advance.

    Interesting... My P3D+ is 1/8" lower in the rear with no one in the car. It's like I have the wrong springs in the front.

    Could you please take some measurements when you have a chance? It would be great to find out what everyone's ride height is like.

    I am showing 28 1/8" at all wheels right now. Previous measurements had the front at 28 1/4" and rear at 28 1/8.

    thanks for letting me know. The springs do settle a little bit after being driven for awhile.

    Is there an easy way to lower it 1/2"?

    I am thinking they need to swap out the incorrect spring for the correct one

    AFAIK there's been no evidence the springs are any different on the P (or the shocks for that matter)
    AFAIK there's still no evidence there is any such thing as different springs on any Model 3.

    The drop is very small, and could easily be just the 20" wheels swapped-out control arms to correct wheel geometry.

    If they were actually going to go to the trouble to develop and test, and have the manufacturing and supply chain hassle, of entirely different springs and shocks they'd likely have given it more than a 0.39 inch drop in the first place.

    I just measured mine. ~28.25 inches on all four wheels.
