Hey Walt,
Thanks for the compliment! I like my little ducktail 911, it's my first Porsche and it has been fun. No, that wasn't me in So. Cal., nor at the Festival of Speed, nor at the Porsche and Pastries events in Livermore either, hahaha. The only events I ever make it too, and I don't go to all of them, are the Blackhawk Cars and Coffees on Sundays. I might have seen your car there once about a year ago. I saw my first and only 50th 911 there.
I would say that I am happy with the Techart springs. My suspension is just the plain non-PASM type and those springs kept the ride quality about the same, although it is slightly more responsive in handling now and looks much better. What kind of suspension do you have on yours? BTW, I did the work myself on mine. Sharkwerks wanted ~$1200 for labor, and I instead bought a Quickjack 5000 and did the spring work myself.
It's getting late, let's chat more later.
