[s-cars] rear differential cooler

[RCaro900SS at aol.com]

Gabriel,
 
Are you talking about overweight dedicated track cars like the S6? I am  also 
having my center torsen differential modified to send more torque to the  
rear. 
 
I know BMW track cars that routinely use coolers or larger casings to cool  
their rear differentials.
 
I am just trying to get information from anyone who tracks their car that  
might have made this modification. I didn't want to reinvent the wheel.
 
Regards,
 
Robert
