Suspension Height - P3D vs. P3D+ vs. RWD

[Brando]

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)View attachment 325542

How can cap to ground be different? you got 3 different tires ?? tire pressure not the same?? I don't get it.

He is measuring cap to fender lip, not ground.

My RWD is all over the place, left rear 27.75", left front 28.125", right front 28.375", right rear 28"

make sure you're on a flat surface and have nothing in the car. How many miles on the car?

i'm asking about the cap to ground numbers - see them toward the right

parked in garage so very flat surface with very slight incline, have maybe 20 lbs. in frunk and 20 lbs. in trunk, 10,300 miles on car, tire pressure is within 2 lbs. all around at 37,38,38,39

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.

My P3D+ is sitting almost exactly like yours, although I only measured the right side. Am a little concerned that the rear is noticeably higher and that others are seeing lower consistent numbers all around. I will probably mention at the service center next week.

 

[mcbarnet007]

Yeah, my part number for the rear spring is different than another test drive P3D+ that was at the showroom. It just doesn't look right with the rear that high up.

 

[mcbarnet007]

For reference, my rear spring part number is 1044472-94-A. The one I saw at the show room with correct height is 1044472-04-A.

 

[Glamisduner]

Yeah, you really screwed up.

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

Good idea on the calipers, adding that to my list

what's your Vin range?

I have 1044461-01-E.

106xxx

 

[mcbarnet007]

Interesting. Not sure why they keep changing the parts. You kind of expect they keep things the same given they want to keep production streamlined.

Could someone with a P3D+ take a picture of the side of the car so we can see the gap between tire and body? I'm super curious to see how that looks compared to the regular suspension.

Here's how the RWD looks with T-Sportline's lowering kit, i think the "After" photo looks much better and hope the P3D+ is similar!

Did you ever investigate this? My rear is a half inch higher than the front

 

[mcbarnet007]

Took it into service center and they measured it and is working with engineering team. I'll update once it is resolved.

Ride height did seem to settle a little bit lower in the back after 1000 miles. Like 1/16 to 1/8 of an inch or so.

Do you have any update to this. I measured mine and I have a 1" variation from left rear to right rear and it didn't settle after 1800 miles.

you should just bring it in to service. They can take more precise measurement for you and see if anything can be done.

 

[Shizzrock]

Service has been languid in their response. I was hoping someone has some sort of info about this. My rear definitely sits 1/2" higher than the front. Others have posted a different measurement. I really want to make sure I have the correct springs, but so far it's not looking like that's the case.
