turbo6bar,
the eurocars are a better choice than the US for the nerf bars because they use the non-hydraulic shocks to mount to the chassis. The front and rears shocks swap positions and one of them(can not remember which is shortened a bit w/ a torch). Unfortunately I can't provide pics becaus it was done so long ago. The BW Nerf bars are just properly shaped iron that bolts to the oem shock pads. They just sit behind the bumper caps.
The nerf bars just provide a bit more crush zone. They do not replace the function of the oem bumpers. The front nerf bar is a great place to hang an oil cooler from.
They can easily be fabbed from aluminum for more weight savings. The bumper strut/shock is a simple assembly
The BW pieces are very nice, light, finished nicely and look factory installed. They are also tough.
