Hey guys I was looking under the car with my friend and we were trying to figure out ways to drop some weight on the car over then the obvious titanium parts. We noticed the subframe in the car is steel and coming from a 350z as a past car I remember Nissan used aluminum subframe and carbon driveshaft. I know this car is a lot higher powered car but I'm wondering if anyone else has thought about this or a shop has fabricated one? I think going aluminum would drop an easy 30-40lbs off that rear end! Any thoughts?
