I cannot ascertain any difference from factory fill, maybe after I get a few miles on the stuff.

next is the front differential on C4

anyone have any pics or advice on how to do it, im going to use Fuchs Titan Sintopoid for the front differential

 

I was hoping that you did the Swepco fill in the winter time so you could provide a comparison. I have been thinking about switching to Swepco on my 997 since it improved the cold shifting on my 911.

 

I meant swepco 201 NOT 210
