I'm going to try 34 front..and 38 rear think that the shocks should be OK on my 03 Cab at 38,000 miles, and new Sumitimo 18's ...a garage kept "cruiser"
I bought this car because to takes me back to my first 911, an 80 that I bought around 82.....(long story about how I probably almost became a Ferrari person)
It was a tripe Black Targa, that I kept for about 3 years....now all these years later, 6 911's, 4 Boxsters, 2 356's and a 914 later...
It just caught my attention and I "needed a 911 to justify my PCA membership of 40 years....
So, it's a weekend cruiser...and social PCA event car......

I did some looking into this a while back and after experimentation am now happy with 34/39psi with 19’s and stock widths and sidewall on my C4s. There is no perfect psi, just what works best for you to deliver the best ride/handling while satisfying needs of the tire for even wear. And of course requires proper alignment and camber settings.

I dropped the pressure front to 34 (warm) from 38 and rear to 38 from 44....huge difference in ride feel.....
