delrin will always wear much faster than alloy, so faster than the alloy diff (why is everybody complaining about that? I don't see any wear after 1 month of pure modified racing!!

the delrin cups need to be replaced as soon as there's a groove in it where the pin hugs in (NOT good for the cars performance!!)

in modified you will want to change outdrives every 1 or 2 race weekends

but as it's cheaper, you can replace it more often
