I've created a new site for ringtones as I couldn't find any decent sounds for my Razr phone anywhere else. It's still a work in progress but the first ringtone up is a 997 Cup at full throttle.
I hope everyone likes it and if anyone has some great Porsche (or other makes) sounds, I'd be more than happy to put them on the site.
