I am interested in buying some Eibach Pro Kit Springs from an individual seller, but I am concerned whether they are the correct springs for my car(2007 Mazda3i). The correct part no. is 5545.140, the pic the seller posted shows a no. 5545.002. After searching, this does not appear to be a Eibach part no. Is this a no. that is on the springs, along with the part no.?
I contacted the seller about my concern, just wanted to pick an experts brain while I waited for his response. Thanks!

Evidently Eibach does not put corresponding KIT no.'s on all parts. The 5545 no. designates them as a fit for Mazda3. The front and rear springs are distinguised by said number.
