This website is a little flakey and take a while to load, but I bought my DTC-60s from Bimmerworld and their application chart is a lot more accurate than Hawk's own:
Looks like the 335i uses pad shape 534 for front and 362*** for the rear.
***Hawk does not currently have proprietary part numbers for these locations though we have found these pad shapes will fit with slight modification to the backing plate clips.
Hawk representatives gave me the same answer wrt DTC-60 fitment for the MZ4 Coupe. What I found is that a lot of BMW's pad/backing plate numbers are interchangeable and you've got to get a little creative when it comes to the actual fitment. Sounds like you can either run it without the spring clips on the inbound pad or spread it out to fit better.
