how much time is needed to change springs?

[arcticnorth]

hey guys,
i brought my car to change my springs to eibach's.my mechanic said it was a much bigger job to change them than normal.because he has to take alot of stuff apart that he would not normally have to on other cars.so i was wondering about how much time would it normally take.thanks guys fo the info.
p.s. yes i did call porsche but what ever they say is always around 50% more than anyone else.
