Hi All! First post here
I have a 2017 GTPP and have recently installed FRPP Track Struts with BMR SP083s and the BMR front sway bar (keeping stock PP rear sway bar), along with the MM CC Plates.
I've also installed the Steeda Roll Center Correction kit as well, and have a spacer in the back to raise the rear up .25 of an inch (total drop: 7/8 in front, 1/2 in back).
My tires are Michelin PS4S in 285/35r19 on SVE S350 19x10s, square setup.
I intend to use the car for roughly 5 track days a year, but also as a daily with a relatively short commute (~10 miles round trip). I also do a fair amount of spirited driving through the hills and canyons about once a week, probably equating around 300 miles a month driving at around 6/10ths. This meaning each year: ~4000mi spirited, ~3000mi daily, and ~500mi track driving
I'm currently deciding on an alignment, and was wondering what a good place to start would be. I was thinking around:
Front:
- Camber: -2.2 degrees
- Caster: 7.2 degrees
- Toe: 0.01 degrees (Aim for zero toe, but prefer slight toe in rather than toe out)
Rear:
- Camber: -1.7 degrees
- Toe: 0.1 degrees per side (slight toe in), total 0.2 degrees (not to exceed 0.25)
- Thrust Angle: Zero
I've heavily debated the amount of camber to run, as I do not want to have too much wear to the inside edge of the tires from non-track use. I am unsure if -2.2 in the front will be too aggressive...
I'm also curious as how the front sway bar settings will affect tire wear and handling. I've read that a stiffer front sway bar setting may actually increase handling by preventing the MacPherson strut from compressing into the camber loss region of the suspension travel arc. However, I'm not sure if the PS4S (being a 285 non-R compound) will benefit from anything more than just the softest front sway bar setting.
Any critique or advice is much appreciated Thank you!
