I'd extend a little more charity to H&R. We don't know why they would list the springs separately. Maybe it's done for some administrative reason, or maybe it's just easier for customers to enter their specific model so they know they can use the spring. If it was just listed as "Civic" a certain number of Si owners might assume it doesn't apply to them and overlook it or vice versa. I don't think they're trying to give people the illusion of choices when its presented in a way that makes you believe the other springs aren't viable choices for you.just being sarcastic !
anyway i was just frustrated with the list of model numbers turning out to be the same product , its a bit of a fraud if u know what i mean , giving an illusion of many customized choices.
