well depends on what set they are....
they make 2 different sets of springs....
one drops the car 2.25 inches and the other set drops it 1.6 inches.....even with 1.6 inches you are pushing it (so i hear)...
i believe (and correct me if im wrong) anything over 1.5 inches puts stress on driveaxles and such
and had a quote sent to me. They quoted me about $199.00 for the set. I was just wandering if they were worth it 
or not
