I'll be honest, I have no idea what the stock TT suspension is supposed to feel like. My suspension was completely gone when I acquired the car. During my ownership I installed Powertrix FUCAs, Tension Rods, RUCAs, Z1 upgraded lower control arms (ES poly bushing/new ball joint), Energy Suspension subframe and differential bushings, Tokico Illumina adjustable shocks + Tanabe springs as well as 18" wheels. Also new HICAS inner tie rods and the outter ball joints.
I'd be happy to take any of you old heads for a ride if you're around Philadelphia, but I honestly think the suspension is super plush considering everything that has been done. Maybe I'm used to it though, my Subaru Legacy GT was on Koni's + Swift springs and my 335i is currently lowered on Koni's and Eibachs.
