I just received my HR springs today for my 6gen 4cyl Accord. The only problem is that the rear springs has the part number of a 6cyl instead a part number for a 4cyl.

My question is for people that had bought HR springs for their 4cyl. Did your springs come with different part number for the front and rear?
Shouldn't there be only one part number (set of 4 springs) for the 4cyl?
