Since I already had the 09 springs ($40), had time on my hands and had to get in there anyway to change a CV joint boot, I decided to swap them in. It wasn't too difficult and dropped the ride about 5/8" to 3/4". It looks still stock but way better than before. At least it doesn't look jacked up now! Wheel opening dropped from 27" to 26-3/8" or so.
Here's some info on them for anyone interested. Another data point for this list.
The ride is slightly firmer. The wire of the 09 springs is thicker than the original 07 springs. Rears were 12mm, now 12.5mm; fronts were 13.1mm, now 13.5mm.
Color dots on 07 springs were blue, yellow, yellow, yellow on rear and red, red, white, white on front. Now dots on 09 springs are blue, pink, yellow, yellow on rear and yellow, white, white on front. So I didn't have the Euro sport-tuned suspension that VW claimed, but I do now! :wink:
