The bottom motor mount tubes cut through the stock FC pan.  That and the 
weight was the reason I went with a steel/glass hybrid in the first 
place.  My hybrid was much lighter than the stock unit, but I never 
weighed it.  I don't know exactly how much I'll save with the .025 
replacement, but the goal is to make it fit and possibly cut down on oil 
volume more than just using thinner material.  Weight loss from thinner 
material is just a bonus.

I'll weigh the hybrid unit after I pull it off.  I could have just 
repaired the leak by beefing up the area a bit, but I just wasn't 
comfortable with how closely the exhaust ended up being to it after 
everything was installed and fitted...even with the shield I installed.  
Anybody with a less tightly packed installation want to give a composite 
oil sump a try?
