Put some 1:30 & better 60' times and a trans. brake up against an 8-3/4 housing and see how long it lasts! I have a useless back braced housing to prove it! If your not running a class that your looking to shave hundreths of a second off of, spend the $$$ and go Dana....your budget will thank you in the long run!
