So I take it these are the ones you bought?

H&R SPORT SPRINGS for 92-95 HONDA CIVIC, NON 4 DOOR EX (-1.80 F -1.60 R)
ID #: HR 29863
Adventon's Price: $120.69 Set of 4
Retail: $269.00

Hmm... If they're supposed to be the correct springs, perhaps the shocks are for the wrong year civic? You said that switching them front to rear didn't help at all? Do the front and rear springs look exactly the same?
