The Selespeed was launched in Denmark with 15 inch alloys (later on, 16 inch), carbon fibre centre console, 4 power windows and winterpack aircon. I therefore fitted the lowering springs from H&R ( mind you, I have tried cheap options on other Alfa's, and didn't want to go there once again). And I'm very satisfied.
I know this guy livin' in my neighborhood who had the original sportspack retrofitted. He just hated the ride so much he bought an Audi A4 turbo instead. But with 18 inch rims I still reckon my car has a (somewhat) comfy ride.
