Hi everybody
I installed it in D2Technik on Alhambra,
THe other shops like F1motorsports(Vincent) or Impex autosport(Harry) are good choice too, For My 97 E420 springs they can gave me 300-400 plus tax including installation, Check their websites for further details(f1motorsports.com and d2technik.com) installation usually cost about 100 dollars, for springs installation, for shocks would be more expensive. I am surprised that the costs of installing springs from one of you guys is 400 bucks
