T spring question

Hey I've got a question for anyone with FRPP T springs: I bought a set and got them a few days ago. I noticed that on the actual springs, the fronts are labeled "M-5300-TF" and my rears say "M-5300-KR" . I figured the TF probably meant T Front, so is it normal that my rears say KR? I know there is a K spring kit, so I want to make sure I have the right springs. Thanks!
 
Those are correct. The T kit uses the rear K spring.
 
Okay new question! I installed everything and I love how she rides and I love the new stance. But I noticed on the old front springs there are rubber insulators on part of the spring. I did not put them on the new springs because they are glued to the old ones. Should I be worried about this?
 
So I called FRPP today, and I was told that the isolators on the stock springs are not meant to come off, and that the new T springs did not need them transferred on. Has anyone heard anything else from Ford Racing to contradict this?

I believe that. I didn't relocate the ones from my stock ones to my P springs, but those came with an isolator installed between the middle between the soft coils and the rest of the spring. So I think if FR wanted an isolator on those springs, they would have come with it.
