Nissan technical explained WDHs to me, in relation to their cars (im blessed i know)
My partner says if i lost all the useless crap stored in my head, and kept only the important stuff, my head would still deflate like a 1998 new years balloon.
Now; he said the Navara (best car ever, thats why we use it in this example) is engineered to perform all functions such as braking, steering, carrying, towing, looking great etc ... all within its engineered and tested limitations without external unknown assistance, or forces not taken into account during the design/engineering of the car.
Anything thats added, but obviously not limited to just WDHs, such as raised suspension, loaded roof racks etc can have a dramatic and unknown effect on the cars designed and intented handling and performance dynamic. With the huge amount of force, including twisting, that the big hooowa Reece WDH can push through the entire length of the cars chassis from one point on the cars extremity to apply across to the entire length, i can see why Nissan are saying ...... me dont think so.
Its an extraordinary amount of potentially destructive power, applied in many different directions, that forces a 2.0t car to pivot large amount of weight and to force that weight down at the front of the car ...... almost 6mtrs away by twist the back of the car.
All this is happening when Nissan hasnt made a single step in applying any of it to the cars design, and with the added fun of a 3t van bouncing, pushing and pulling on the same focused point of pressure at the same time.
It does beg the question "whos right"? Nissan has no apparent vested interest, but Haymen Reece has a huge vested interest. Nissan arent non committal, they simply say, not on our cars. Hayman Reece say yeah, yeah ,yeah.
