Can anyone help with mazdaspeed spring numbers?
 

Today christmas came early. My buddy gave me some mazdaspeed/eibach springs.

Can anyone help me decipher the part numbers. Printed on the springs:

9EP5 34 011 16,95 (front)
9EP5 28 011 16,95 (rear)

Anyone know what rates these springs have? I expect someone with a ms account would be able to findout.

Thanks in advance
