I have been thinking about buying the Bilstein B10 suspension kit and Eibach arb kit for my Lupo Sport, which I have owned for the last 3 days, but can't decide whether it is worth the £520!? Im looking for an improvement in looks and performance, which I'm sure it would do, however I don't fancy paying another £350 to have it all fitted!! So... Would it be worth it? (i.e. do others have a similar set up, and what are the benefits?) and ... Would myself and my fairly mechanically minded brother be able to fit it ourselves? (thinking front arb, could be a problem, unless we had a ramp!?) So any advice or guidance would be appreciated!
