Mountainpass performance Coil over AWD "Comfort" not adjustable in rebound/compression ARE stiffer than Sport AWD Adjusted to Softer setting?
AND
Coil over AWD "Comfort" not adjustable are stiffer than stock?
I want something "sportier" but I will never need to adjust for specific use (I don't race, I don't plan Autocross , IlI'use the car only on streeet for occasional sprinted drive).
The "Comfort" definition is worrying me. expecially because I'm the original poster of this discussion: "

"2021 p3D handling concerns. I'm disappointed [because suspension too soft]"

MY plan is to install Solid Front Lower Control Arm Bushing, master cylinder barace (just arrived in Italy to my home today)
and later:
Cyber rear traction and Trailing arm
Then:
A MPP coil Over kit.

The Comfort spring rates are still technically higher than stock, they just don't ramp up as aggressively until the bump rubbers are engaged!

Just installed the Montainpass performance brake master cyl brace on my 2021 Performance
I was not ready to 2 inconveniences :
1) the little hole (where the m6 bolt and nut and spacer and washer ) was with a plastic clip holding a big connector.
I had to smash it and remove and search a new places for the wiring harness connected to the big connector.

2) I have FULLY threaded the adjuster into the master cylinder brace, but when istalled there was absolutely NO room to thread out the adjuster until the base touches the master cylinder. and I had difficult to thread the big bolts because the adjuster was already against the master cylinder (forcing it).It's like the whole brace (with the adjuster fully threaded in the brace ) was too long.
A frined of mine with a 2019 LR AWD had no connector interaction (no connector no wiring) and no "too long" brace.

I noticed this on my neighbor's brand new 2021 M3P (Late March 2021 build). It appears they have added an additional disconnect loop to the emergency battery disconnect and it uses this previously unused hole to retain the harness. MPP might need to update their instructions.

@MountainPass I picked up a brake brace for my 2021 m3p but haven’t installed it yet. Any suggestions??

Can't comment on the wiring harness change, but the sometimes-almost-too-long-nature of the brace has to do more with the Tesla production tolerances, which are too high. Mine was also tight, even all the way backed out, but it still worked just fine, and didn't compress the master cylinder/firewall. I have yet to hear about someone where they had to exert force on the bracket to get it into place. Curious what @MPP will say about the wiring changes.
