I know that the regs have changed on this, and that the sportster rear wings are no longer compliant (they where OK under SVA - Now they're not under IVA)
Does anyone know what the regs are now? As far as I recall, only a certain portion of the tyre can be viewable from the rear of the car. I need to know how much, as I'm intending on making some aluminium extensions to over come this issue for the test
I've been googling all lunchtime, but can't find anything.
This is from the SVA to IVA article I posted up from complete kit car:
After the centre point of the wheel has been established, the tool (clear plastic template) is leveled with the ground and a forward angle of 30 degrees and a rearward angle of 50 degrees (from the vertical) is noted. Looking down on the car from above, if any part of the tyre is visble within this sector, the car will fail the test.
Further more, the wheelarch must continue down behind the wheel to reach a horizontal plane 150mm above the wheel centre line

When they did the "Pseudo" IVA test on my car they used a fancy protractor like gauge. I beleive that the gist of the rule is that the tyre (viewed from the rear) must be covered as far as a line running parallel to the ground from the centre of the wheel. Mud flaps are probably the simplest answer. You could make 'em out of some of the ribbed rubber mat that's favourite to cover the floor.
I am sure there is a thread already about this....
All I was planning on doing was getting some offcuts of ali, bending them to fit under the rear wing with a portion droping down vertically until it hits the magical 150mm plane.
A circular cut out would allow them to slip over the bodies for the tail lights, and they'd be held in place by the light clamps - so no extra holes to be drilled (and filled later on). Some titanfast will make them IVA proof, and they'll also give me something flat to stick the rear reflectors on.
They're not flexible enough to be mud flaps, and they're easily fall-offable later on.
I do think it's funny, they come up with new guide lines, we find temporary solutions to get through the test then revert back to standard again. Makes you wonder sometimes why they bother with some of the regs!
Your solution is certainly more rigid than mine! And has the advantage of giving you something square to put the reflectors on. I had to modify my solution as it counted as a sharp edge. http://www.flickr.com/photos/33105452@N05/3691403032/
These 6 quid mudflaps off ebay seemed to pass OK although as you say, he was umming and erring a bit. He consulted another book of guidelines which said in big letters 'mudflaps do not meet this criteria' but maybe he was reading a different part of the page or maybe I interpreted it wrongly?!
Check your 30 degrees from the vertical on the front ones, it was pretty close on mine.
