|This tube goes from the forward leg up at and angle through the firewall to the top of the shock tower…||to triangulate the shock tower to the main structure of the roll cage.|
We also noted an odd point of the cars construction. The top part of the main frame rail where it welded to the firewall was simply open. This made a weak point in this highly loaded area. Why Nissan did this is a mystery. It must have something to do with controlling crush characteristics in a bad crash. This however is very bad for stiffness. We added reinforcement to this area boxing it in.
|Wherever the tubes pierce the firewall, the gaps and holes are plugged with sheetmetal to couple the tubes to the unibody.||The front suspension is thus completely tied to the unibody and the cage to make a very stiff structure.|
We are now well on the way into the conversion of our Spec-V from a sporting shitbox to a shitbox with an attitude. Stay tuned, in upcoming segments we’ll complete our cage and turn our attention to the motor.
|Our cowl triangulation goes from the shock towers back into the main part of the cage. This provides tube frame like stiffness to the noodly Sentra Chassis|
