Just on a side note to this. When I last spoke to the Vicroads engineer, he told me that they would not necessarily knock back rose jointed/rod end suspension points, but he would need the technical data and strength test results (if any) before he could pass them for street use.
Well, there you go.
The easiest thing is probably just to not let rego lapse and don't get caught :-\
I can vouch for the over kill of these rods, they are HUGE. 1" tube for the rod and the mount is made of 1/8" (guessing here) steel. It's not going to fail any time soon, that's for sure! They also weigh a metric tonne tho, a kilo or more each compared to the standard rods. You do neeed to keep an eye on the nuts that hold the rod-end to the body mount, I had one rattle loose and fall off, which was totally my fault for not checking they were tensioned.
TTT make all of their stuff far stronger than it needs to be, it's one of the reasons I have pretty much their entire catalogue installed on my car now, purely ease of mind knowing I'm not going to snap something like I did with the standard t/c rod.
