G`day mate, glad to hear your still alive and kicking.
I have a QT front and rear, they have been on a couple of vehicles now and I an very happy with them, the front has taken a few big hits and it just deflects everything off it, it is a bit different shaped now but still going strong, so in my books it is doing its job perfectly. You can also drain the oil with it in place.
I disagree with the rear, I only have the place which protects the light crown wheel cover on the back, it saved me at least once when I reversed into a big rock in front of a pub in the UK, they are quite cheap and non obtrusive.
An aussie escaped from london, now in Dubai.
