IIRC, superalloy had rather low protection value vs. weight. I explored this option once but I dropped the idea (for some reason). Best bet is the military composite plating, which is light and durable, or was at least few weeks ago, and more importantly far more common.
You might find a superalloy plating or two in bank vaults, but that’s unreliable as well.
How many plates would you need? If it’s anything above 10, I’d say forget it. Not gonna happen in any tolerable time frame, not without debugging/cheating or upping the item drops considerably.
Right now I’m thinking that a good way to reduce vehicle weight would be to switch the heavy duty frames to normal steel frames. I mean, I always go with heavy frames, so making that kind of engineering decision seems like new and exotic to me… Or at least switch the interior frames, since they get hit the least.
It’s the front 2 rows that take the most hits, so don’t spare protection in them. You could omit protection from the rear and avoid backing up on things, but I think I’d just omit armor from the interior sections first before considering leaving the rear unprotected. Always adapt your driving style to your vehicle’s status, and adapt the vehicle to your driving style, which is to say bump the hulk with the green quarterpanel, not with the red one, and when the front is yellow, it’s time to start driving over things in reverse.
Vehicle weight reduction seems like a complex sport and might deserve its own thread.
