The 370Z Weight Reduction Thread

[SPOHN]

I want to go with a fuel cell. Get rid of the OEM tank. Put a 10 gallon tank to save weight and get better weight distribution from front to rear. Which is WELL needed on our cars.

feeling lazy...

let's talk glass removal and replacement options

I've read that lexan is great obviously but any longtime users in here? Can you go over the yellowing/scratching/visibility and whether or not you have a garage or not.

looking to purchase from this site which offers z33/z34

SPOHN claims to have changed out the back glass for Lexan.

Lexan tends to break down (craze) from UV exposure, so Plexiglas, with its' greater resistance to UV, may be a better choice. YMMV

Yeah but the stock tank is low. If you put a fuel cell up in the rear body, you're raising the fuel weight higher, raising CG. Also, even though we want to shoot for even front/rear distribution, I suspect moving weight from the center outwards, even to the rear, isn't a net win. It's still a larger goal to keep the weight centered to make the car more-stable, whereas weight at the edges is like a pendulum. I don't know all the factors and how they play out relative to each other, but just things to consider...

On the other hand, Lexan is much, much tougher and more impact-resistant. Something to think about with rocks and hard chunks of rubber flying at the window, and especially something to think about in a wreck.

Just from what my cousin tells me who flies helicopters, he said the lexan on them gets super brittle after a short amount of time because of the sun and whatnot. I'm sure if your z lives in a garage or is covered most of the time you should get more time out of the lexan than the copters do.

thanks guys and that's what I've read from the Shelby guys on the kit cars...just looking for more real world use!

Trust me. It wouldn't just be placed in the rear. I've seen another 370Z where the whole rear section cut and removed with rear cage in place. The fuel cell would be lower than stock
