I found the best thing to do is to Heat cycle the gears .. the first few times out what you want to do is drive the car easy for 20 -30 miles to get the gears hot .. then let them cool down for a few hours. I don't belive that you have to put 500 miles on the gears before they are broken in. just heat cycle them 3-4 times and you will be set <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Moser said to run them in forward and reverse for two minutes each on jack stands. Then normal easy driving for about 10-15 miles. Than let it cool off for an hour or more. Than drive it like you stole it. Thats exactly what I did. I was at the track that night!!They Dont recommend synthetic fluid.Remember the limited slip additive!!

Awesome. I'm firmly into "Drive it like you stole it" phase at this point. Since nobody has suggested how long this period of the break-in should last, I'll just continue to do it for the duration of the gears' life. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
