Its coming up to xmas and I'm starting to think what I could ask the jolly old man in the white beard for. If I was lucky enough to get some handling mods (Like ATB diff, 300mm brake conversion or strut brace etc etc) obviously I have to declare them to my insurance company, but what is the extra premium like? I'd like to think that because I'm improving the handling that my premium would go down, obviously insurance companys wont feel the same way.
