I have a 1.6 FSI too. Getting my first mod done on Friday - Lowering by 35mm. I'd be very interested in seeing anyone who has had theirs done by 35mm.
If you class putting Alloy Wheels on as a mod, it'll be my second mod.
Been wanting to lower it for ages but finally took the plunge. I don't know much about modding, i've never done any on any of my past cars (Corsa, Polo) basically because they were great cars, I loved them but I have always wanted a Golf (Since a kid) and now I have my car so will actually do abit to this as I will keep it for longer than my past cars, someone I know has suggested an Induction kit, i'm not really sure. I also like to show my exhaust, I'd love the R32 rear bumper and exhaust but I have only been able to find it on one website and it is very expensive.
Look at my garage (In my profile on the right hand side) there are some pics in there obviously pre lowering, but I do have my wheels on it in those pictures. I will post pics after Friday after getting it lowered if I get time.
