Mission accomplished...sort of
. My son and I spent all day on Saturday and got it done BUT, I may need to make some adjustments. First, lets talk ride and settings. Comfort was my main priority so I decided to got one click softer than MPP recommended for bump. They recommend 12 for bump and 12 for rebound in front. I used 13 bump and 12 rebound. For the rear, the MPP recommendation is 10 bump and 8 rebound. One of the install videos mentioned keeping the bump & rebound within 2 clicks so I adjusted both and used 11 bump and 9 rebound. I've driven about 100 miles and the ride feels good. It's definitely smoother than stock and might have a little less body roll (but is very close to stock). I'm happy with the settings and might experiment further but first, I need to sort out the ride height.
First, measuring from the hub to fender is dumb because you can't accurately determine the center of the hub. Why aren't we all measuring from the ground to the fender lip? I took both measurements and this is what I had before. Sorry for mixing units but I didn't have a metric tape measure.
Before | | | | |
| Drivers Side Hub to Fender | Drivers Side Ground to Fender | Passenger Side Hub to Fender | Passenger Side Ground to Fender |
Front | 409mm | 29 3/4" | 411mm | 29 5/8" |
Rear | 416mm | 30 1/8" | 416mm | 30 1/8" |
MPP says with the front spring perch at 55mm and the rear perch at 16mm, the final ride height will be 395mm hub to fender. Judging from some of the pictures in this thread, I decided I wanted to go a tiny bit lower so I decided to take 5mm off and used a front spring perch of 50mm and a rear perch of 11mm. I used digital calipers to set them so I know they were exact. The end result is the following:
After | Drivers Side Hub to Fender | Drivers Side Ground to Fender | Passenger Side Hub to Fender | Passenger Side Ground to Fender |
Front | 380mm | 28 3/4" | 380mm | 28 5/8" |
Rear | 390mm | 29 3/8" | 390mm | 29 3/8" |
Excuse the crappy pics from my phone but this is what it looks like. First pic is both front and rear done and how it sits right now.

To me, it seems the rear is higher than the front. This is also evident in the measurements. The front dropped exactly 1" but the rear only dropped 3/4". I'm wondering if I measured in the wrong place? The MPP pictures weren't very clear. Here is where I measured:

Is this correct? Also, have any of you experienced any settling? I'm thinking I'm going to take the rears apart tomorrow and lower it a bit more but should I wait? If they are going to settle, I'll raise the front up a bit and let them settle to where I want it. If not, I'll lower the rear. Hopefully, it won't settle and I can just adjust the rears since that is easier. Just for comparison, this picture has the fronts lowered and the rear stock.

Finally, I think it would be a BIG help if MPP would provide torque values. I did my best to comb through the thread and watch videos to get torque values but many came from Model 3s and there were some inconsistencies. This should have been included in the instructions.
