My car is 2001 156 2.0 Manual Monza (Nero/Black), I've installed Genuie Alfa Eibach spring and Tower bar at LanceDixon. I also found my original brake is very spongy feel, so I changed EBC slotted Disc, and green pad, Autodelta stainless steel brake hoses.
Also Genuie Alfa lip spoiler, replacement sport airfilter.
I've seen your homepage, your car looks beautiful (especially the front bumper). I've read your message about exhaust. I'm thinking to change the exhaust too. I've talked to Damon about the Remus that they provide. I'm also thinking of Supersprint. Is Remus sound very good on your 147? noise in cabin?
