As someone who mix and matches suspension components pretty regularly, I have to say the biggest influence on daily comfort is tire choice and tire freshness, nothing else.
Also, the ~160 lb/in front springs and the rear springs that pair with them are way too soft for track work. The hard...
I have also experienced this situation repeatedly at the entry to a specific restaurant. Rear droop = zero. With the snow tires, I would probably benefit from disconnecting the rear swayba because the inside rear is always trying to spin. Too bad I won’t.
If this is a tapered NPT plug like the internet shows, the correct thing is number of turns after finger tight, as torque measurement is exceptionally poor for tapered threads. NPT is typically 1.5 to 3 turns past finger tight. Don’t forget to re-apply some form of thread sealant.
My real world feel information: Re-71rs makes me smile. A052 makes me smile more. RT660 does not make me smile.
A lot of of that has to do with tolerance for being very sideways. 660s shut down too easily when the hooning is supersized. The Bridgestone and the Yoko just make me giggle.
I got my 2018 GT PP1 with 1000 miles 25% below MSRP. There is nothing the previous owner could have possibly done to make that not a good deal. I always cross-shop new and used cars when making a decision. My 2012 Mustang was new.
The front aero is quite limited. This prevents giant rear wings from making the cars faster. In XS land, the cars are generally running reasonable angles of attack and wing sizes to avoid understeer city.
