Do you follow the PSI recommendation on the door stickers? Porsche recommends 31 PSI front and rear for stock 18s. Seems a tad low?
Yeah.. sticker recommends 31 for stock 18s but I run 32s all round.~32psi on 18s is a good starting point on the street. For the track I start at 24-26psi.
Up north and literally into a neighboring country. I did hit higher speeds at times and really wasn't comfortable with the lighter floatier front end at speed. Its an increasing age and shrinking cojones issue...The springs might be enough,(will remove float and lower nose) - w/o dive planes
Where did you find a 120 mph area ?
Agree - I run door sticker (33) all around on my 2015 CS. With the new PS4s I feel they have a harder sidewall than the F1 Goodyears that were on it. But I want even wear since we cannot rotate due to size, so I will leave it as Porsche recommends. They are certainly awesome as-is, unless I see a real reason to change them.I've always ran 33 PSI all around with the 20's. In the past I've had P Zeros and Pilot Super Sports and they've felt good in this configuration. This time around I went with Extreme Contact Sports and I can tell the side walls are a bit softer. I may pump them a bit higher to see how it feels. It's worth noting, though, that with X73 suspension, this is the most comfortable my car has ever felt.
