A must for a Corrado tbf. I've kind of "adapted" my standard ones by bending where the spring clips on. It extends the spring so gives more tension on the arm against the screen. Its far better than before, but not perfect if I'm honest. The TT arms are not cheap if bought new from Audi, so ebay trawling or breakers yards are the best bet. The Lupo arms are more readily available and cheaper if you happen to find a couple being broken locally. This and an uprated headlight wiring loom really are must have items for a Corrado.
