Slowest car ever round the Top Gear track?!?
Re: Lowering an a3 1.8t sport
trevorb - how many miles has it done? If the dampers aren't in their first flush of youth (like less than 40K miles) lower springs will kill them pretty quickly, and it costs about the same to have new dampers fitted at the same time as the springs.
You'll also find the car will be hopelessly underdamped on standard dampers with stiffer shorter springs - they're underdamped on standard springs. Unless you're fitting the springs yourself it's a bit of a false economy not to do the dampers at the same time IMO.
