I have just purchased an older style extreme 2 wd and would like to add some more bars to the cage to beef up the protection as my two sons will be driving it. If I do this will I need to have it inspected by cams , its not due for an inspection for a couple of years. It also has FOA shocks all round coil overs and bypass , does anyone have any experience with these shocks or knows who deals with then. Thanks
