Rara Please explain this then...
When i lived in KC me and a friend had STOCK E0 SVT's.. His had a aussie bar. I could get my car on 3 wheels all day. The rear pass tire would come off the ground i have video of it. Me driving his car same speed all 4 tires where planted.. Kinda wondering how your losing grip if 2 tires are on the ground instead of 1..
I think its all fine that your a engineer or whatever at Ford.. But i think that the Aussie bar is a great upgrade for handleing.. if you want me to prove you wrong we can take 2 cars to a autox one with the other without and ill drive both in a blind comparasion. I have Auto-X'd both setups and the Aussie bar is much better than the stock.
