Dood, reducing weight is as good a topic as any on this forum and other vehicle forums. But the Raptor is a unique truck designed and built by Ford to be very capable off road at all speeds.
It's good to talk about it. But some perspective would help your discussion and how you present your topic is important especially when (1) you don't own a Raptor, (2) you say you're thinking about ordering one, (3) you admit to being a lifelong street/drag guy who's (4) never been off road and you call the Raptor a pig in the 2 threads you started. You said that 200 pound weight reduction will make a sizable difference on a truck (that weighs closer to 7000 pounds when loaded with fuel, driver, passenger and some gear/mods).
What noob goes onto a forum like this one and starts 2 threads like that without, at least, first building up a post count so folks here know you're more than a troll err a newbie looking to stir shit up?
How about if we came to your street/drag forums and did that while saying we've never been in a drag car or to the strip?
You may be young but you must have some experience with the internet and forums, right?
As I said, I'm not against talking about ways to reduce weight on the Raptor and I did offer you some very good suggestions early on..."But if you're serious about reducing the weight of the truck then do it right and remove/replace the box in back with something lighter like fiberglass. And gut the inside of the truck too. Yes, take off the spare. And run smaller, lighter tires."
I hope you'll follow-through and buy a Raptor and you're very welcome to stick around here and be a contributor. If you stay tuned you'll get to see how the best in the world at pickup truck engineering and design figure out how to reduce weight in a production pickup truck. Because that's what the Ford engineers have been and still are working on for the 2015 F150 truck.
