Alignment settings for track/street use?
Installing PSS10's tomorrow, TRG sways, RS drop links.
I'm 50% track and 50% street; maybe 10 DE's this year.
I have Michelin PS Cups which I would appreciate if they would last through next season also!
Anyone know alignment specs for a 50/50 track and street mix - thanks in advance.

What run group are you in? How many track days do you have under your belt? How hard you drive will determine the settings you need. Even then, the settings will be a compromise for either street or track, no question.

I think RS settings should be a good place for you to start. Dial in more negative camber settings if you're wearing out the outside edges of your tires. If you do this, street driving will wear out the inside edges.

Do you have a turbo? If so, I agree with Stealth, 0 toe, as much caster as possible AND go -2F and -1.75R camber. More camber in the front makes AWD cars fairly neutral. Also, watch your tire pressures.

I'm at RS height +5mm, and RS alignment specs. After about 10 DE days and maybe 8000 street km my wear is fairly even across the treads, but the rear outside edges are starting to take a beating. I may need a bit more neg in the rear, but agree RS spec is a good place to start for a dual use car.

Hi Jeremy,
FWIW, I went with a bit more negative camber than RS setting: around -1.2 degrees front/ -1.7 degrees rear. This worked very well with my PSS9s and 22mm/21mm sways both TimeTrialing and daily driving. It has now been a few years and several tire changes since I have tracked my 993, but still a daily commuter. Tire wear is still excellent and the car always feels secure as well as confidently planted on the street (not at all darty). If you spend as much as 50% on the track, I'd go with more neg camber than RS ...IMHO anyway
