Has anyone out there tried the Abt Sport springs? I'm considering trying these springs mated to Koni shocks after seeing an A4 that was using them out at Blackhawk this weekend during the Quattro Club event there. I loved my Koni's in my GTI VR6, but I'm just not sure of the ride quality on this car. I really don't want to sacrifice too much. For everything other than track events, this car will retain the sport 16" wheels.<p>The ride height, to me, looked absolutely perfect, and the owner of the daily driver claimed that the ride quality was great, but we all know that ride is completely subjective. I'd like to hear a few more opinions if anyone is currently using these springs on Konis or Bilsteins.<p>-doug
