There is a bit more involved, but you get the idea..

I found for my driving style this is the biggest problem I have at stock power levels...The rear diff "opens/slips" and I will blaze the inside tire on corner exit. I have been told my "the man" that this is common only in 10/10ths driving situations in the 1LE.
I chose not to use the Zl1 set-up as I dont want to add the weight penalty to the car (It is a heavy assy) and I don't plan on anything more than bolt-ons down the road (maybe 500whp) and drag racing will be limited. I am following the Z/28 lead (torson diff) but my timing doesnt allow me to wait for it to become available through the dealers so I am going with an Eaton Detroit Trutrac (mechanical similar/same style) over the winter.
