Tire Pressure for PSS?
 

I am terrible at finding a setting for my 17/45R/225 PSS on stock wheels.

What would you recommend for Front/Rear PSI hot?

Aim for 30 psi hot.

Its a good starting point.

Once you get to the point of really 'feeling' the car, try a few psi more or less, and see if you like it.

I like mine at 36 psi hot both F/R for OEM suspension

Really?... I have been trying 36, 38, 40 hot!

Ok, would coilovers need less or more psi? I am running Bilstiens B14's. I just bought HVT camber plates since I still have understeer.

If ur car is understeering with coilover, try 34 psi front and 36 psi rear or go for adjustable sway bars to correct understeer, typically make rear sway stiffer to induce oversteer

How much camber are you running?

Front Driver: Front Passenger:
Camber: -1 9/16 -1 3/16
Caster: +5 7/16 +5 7/16
Lowered: 1" 1"
Toe: 0

Rear Driver: Rear Passenger:
Camber: -2 1/4 -2 1/8
Toe: In 1/16"
Lowered: 3/4" 1"

Plan is to bump the front chamber to -2 1/2 with the HVT plates.

I think a good question is, what is the car doing that you don't like?

Fix the alignment. If you're on track when we're out there, don't hesitate to get in touch with @CSG Mike.

On a super side note, I'm going contact you regarding that 3M Clear Bra stuff. :thumbup:

You'll probably have to run a bit higher PSI if you are looking to get the most life out of them. I typically run 36psi hot, but the shoulders of mine are corded now.

Honestly, I really dont like the MPSS at all on track. They were a vast improvement over stock, and were good for the first two events, but by the 3rd track event I noticed horrible shoulder wear with my camber maxed out on stock suspension with the whiteline camber bolts (around -1.6* up front), and the tires just had no grip anymore. After 5 track events (8 track days total - 2 of them on the coilovers with -2* camber) with really no street driving, the shoulders on the MPSS are corded, and have no grip whatsoever.

I'm running RS3's next.

Sorry for the off topic rant, lol.

Need moar camber!

Gah I know, camber plates are next. add it to the to-do list!
