Subtle Precautionary

Chassis strengthening, regulation abiding and extra safety.. all covered in flat black to appeal less to nosy police officers.

Although it's only bolt-on, i tried my best to keep the frame strengthening part as effective as possible. I'm no expert in roll cage but i believe that the most important part of a roll cage when it comes to frame strengthening is the tie-bars. I don't know this is the actual term for it but i'm referring to the bars pointed by the arrows below.

These bars ensure the frame doesn't flex by keeping the main bars in their place. It's hard to explain but i'm sure you get my point. In the simplest way to explain that i can think of, two vertical legs won't spread out easily with one rope tied across the legs. This is the function of those tie bars. That being said, when it comes to frame strengthening, i'm sure you can deduct yourself that 4-point roll cage is useless. It only strengthens the part behind B-pillar to the strut mounts.
