An Audi A4 built for the 1996 BTCC championship. Things to look for: 1) The way all the tubes come together at junctions. This has been the case with every cage we have looked at but it happens to be especially obvious here. 2) The "X-Bar" which extends horizontally back from the middle of the main hoop (at the driver's shoulder height) to the rear subframe pickups. 3) The way the main hoop splits into two as it travels up past the driver's shoulder height (we saw this before). 4) The lack of a seat back brace and the way the shoulder harness is attached quite a distance back from the driver in order to allow some "give" in a crash.
