As many of you may know, I have been actively pursuing Club Racing specifications and classification from the major sportscar sanctioning bodies. They have been making me jump through hoops with paperwork and the sort...

SCCA has given me till Dec. 31st. to submit the Club Racing Request Form for inclusion of the Crossfire in the 2006 season. The form requires five pages extremely specific information on the car, of which I am missing some key parts...

I am hoping that someone in the forum will be able to help me with the missing information, as I have made numerous phone calls and e-mails to DC and they have not answered my queries... Below is a list of specs. that I have not been able to ascertain from any of my manuals or online...

If anyone can fill-in the blanks, I would sincerely appreciate it...

I've got the rest of the information requested by SCCA... Anyone who can help with this stuff would be greatly appreciated... Remember, I have a Dec. 31, deadline for the 2006 season... Otherwise it will be another year before we can get the car into SCCA...

Thanks in advance for your help...

 

You might get some help from the tuners like Renntech and such, as I suspect they are the only ones who have done engine rip downs.


Good luck.

 

Try e-mailing Mercedes direct, the first 2 are measurable with an inclinometer. MB should be able to e-mail you all the other spec's since they are available by taking the measurements right off a disassembled engine (in other words, they wouldn't be proprietary info). Good luck, most manufactures in the old days were happy to help with requests like this because racing ALWAYS seems to help sales.
