Sorry about that, was suppose to be a 6 and not an 8. I must have still been half a sleep when I made the post this morning.
No offence but that is stupid. Adding in a 2nd tube and than boxing them in with some type of “chainlink” simply adds weight. And considering the Front is attached to the lower rad support and the rear is attached to the frame/sway bar the likely hood them of tweaking in word is slim, hence why only 1 tube would be required.
Lastely, these are more beefy or heavy duty vs that of a Nismo Piece to begin with as the lower portion is actually boxed in fully/proper and both ends of the tube are braced rather than just one.
