Replacing subframe for weight reduction

3917 Views 7 Replies 7 Participants Last post by  god2ila
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?

Anyone? Did I post this in the wrong section maybe?
Might not be good for the balance of the car. If you look at some of the suspension components from front to rear, you'll notice that some of them are of different material. Probably done for weight distribution purposes.
I engineered an aluminum/carbon honeycomb front and rear subframe for the cars but the logistics in getting core exchanges seemed to be cost prohibitive. If you're interested PM me.
OP: I guess you are talking about the rear sub-frame. On your old 350z, the rear sub-frame only housed the rear diff. On the GTR, it houses the entire transmission. There has to be reasoning for this, considering some of the over-engineering things Nissan did on the R35.
I think it might also be good to think where ELSE you can save or loose 40+ lbs and many threads has shown that this is easily possible.

Racing seats
Carbon Fiber Hood or trunk
Aero wing
Titanium exhaust
Carbon Fiber brakes
lightweight wheels
Non runflat tires
