K guys, just got the R-S3's put on and can already tell they are a better tire then the MPSS...Smooth, quitter, sticky and have more grip.

The question i have does everyone use the pressure specs in the driver door jam.
29 front and 33 rear. I have only had this car for 3 weeks... The original owner had the pressure set to 33 front and 36 rear on the MPSS.

This is a street driven car and i do drive the car hard on the street. What is the pressures everyone is running on the street? or if using the R-S3's what pressures and why?

oh and its a 08 GT3.

Door jam pressures for the street. If you exceed 38psi while driving hard, maybe drop psi or two.

Thanks ChrisF very much appreciated!

On track, I run them 37-38 hot... On the street, I run 31/35 but that's usually just to/from track... I have MPSS for street.

I'd go with ChrisF's advice...
