Sorry for the delay in reply, Ive only just noticed this. They run from inside the car thru the firewall to the struts, then from the struts down to the front of the chassis legs. There's crush tubes thru the chassis legs thru which its bolted and from the underside there is another bar that runs from side to side. Basically a front end cage. It locks the whole front end together for extra rigidity. I've run it without and it does seem to make a difference with the handling and power to ground. Ive also tagged the engine mount to the bar for a bit of extra strength.
