There are two H & R Sport Spring kits for the 96-00 Civic models.

One is part # 51865 for all 96-00 models

The other is part # 51865-2 for the 99-00 Si models

Does anybody know if there is any difference between the two?

According to the Spring Rate post on this board, the spring rates for the H & R sports are 330 Front, and 280 Rear, both progressive rate. Does anybody know which kit these are for, or if are they both the same?
