Update: I understand that even though all the testing was done for the srt6 and N/A crossfire AND THE MERCEDES C32 there is a problem with the axles coming out of the Wavetrac after it warms up and cools down,, a very quick fix is to get a used set of axles from a N/A or srt6 just to be on the safe side. spoke to Devin about this and it may cause a hold up on any slk's,, Steve you can tell everyone how and what fits ,i believe you have crossfire axles correct? not my suggestion,, I am just the reporter,,, jim
