How to determine which Brembo kit
 

I have the Brembo brake upgrade on my E36 M3 and I need to order new pads. I called tirerack just to see availability (nobody was in today at Pelican) and they said I needed to know which kit number I had. I bought the car with the Brembos on it and there are no records showing the details. I looked all over them and see no numbers, etc. The outside diameter of the rotor is about 328mm and 28mm wide and 17" wheels fit over them. I see one choice that has rotors this size but it says that 18" wheels are minimum. Any help figuring this out is appreciated.

Edit:

Nevermind, I found it based on help from someone on bimmerforums. I used this link to the Brembo product catalog:



to determine I have the "Lotus" calipers or A or F style.
