Hey ive just bought a 2005 bmw 120d se (163) model. automatic, silver, heated seats sensors etc... well basically im young and i want big alloys, so ive found some 19 csl rims and i need some advice. will it fit and are they too big for the 1 series, and will i encounter any problems with 19 inches. secondly im thinking of remapping it and my question is, is that a good idea or a bad one. anyways thank you, hope to hear some feedback. p,s former audi person :)
