Why choose this weld-in G80 Sedan V5 roll cage?

The V5 goes one step further than the V4 with the full set of bars, without any increase in the stated weight. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly. For a G80 that is subjected to heavy structural loads, this is the most complete answer.
