Granted, third - party bumpers impart a greater degree of protection to our FJ Cruisers - be it from trail impact, reckless drivers, and the like.

What does that turn us into on the highways? Would having one of those all - steel bumpers enhance the vehicle as a kinetic energy penetrator, or wouldn't it? Would having such a bumper increase the risk of us inflicting more damage to others in an accidental freeway - speed collision?

Just a thought, wondering what your opinions were.

The very rear cross member on the FJ is rock solid. The rear bumper attaches to it so I seriously doubt that an aftermarket bumper would inflict more damage to anyone that would dare hit one of our precious FJ's! Besides, the purpose of vehicle safety is to protect the occupants. Not to worry about someone or something hitting us!

cheers,

Understood :lol:

What if the tables were turned, though?

Of course, that person should not be driving in the first place!

Regardless, would having one make US more dangerous missiles?

Im not sure why Im weighing in here but basically yes it would. First of all its greater weight and as such it does increase our "inflicted damage." Also as all aftermarket bumpers accept perhaps Lucrum are made of solid materials this would not dissipate the impact forces as much as the worthless bumpers that are OE. That being said the OE front bumper is...well offers no protection as all it is is plastic mounted in front of a center frame rail. Bottom line ...you betcha it increases the damage we would do and frankly Im just fine with that.

Before someone flames me for the Lucrum comment. What I am referring to is the fact lucrum maintains the peripheral "stock" bumper. Im not ragging on Lucrum. Truth is the have a fine product.

KE= .5 x mass x velocity squared.
Mass= weight x gravity 32.2 (unit of measure is called slugs)
Velocity = speed in mph x 1.47 (mathematical constant rounded 1.46666666)

So yes the heavier the vehicle(from added bumpers sliders Ect)will increase kinetic energy

The biggest problem with the FJ is that the majority of rear-end encounters is with the spare tire, which subsequently sends the impact and damage to the rear door.

I like the spare mounted on the rear for easy access (and not taking up space in the cargo compartment or underneath the truck). However, I sure wish they would've designed the rear bumper so that it would somehow extend beyond the depth of the spare tire.

Ironically (and unfortunately), the rear bumper on the FJ seldom sustains much damage . . . . making the rear bumper virtually worthless in a lot of accidents. :rolleyes:

The older FJ40 solved this problem by adding "bumperettes" to protect the spare and rear tailgate.

Mine is bigger than yours. :lol:

Yes, to some small degree. Just remember there is always a much bigger, heavier, more dangerous missile in the next lane or coming the other way - all the way up to a big semi tractor-trailer.

My observation also.

WoW! Slim! You must be the smartest member on FJC Community. No offense but come on man! Speak English... LoL!

It's all relative. We would cause more damage but certainly not more than say, a bus! A fact to consider is that modern vehicles are built to absorb impact energy. This is why some accidents look so bad and folks walk away. Say you're in a 1965 Oldmobile Delta 88 and struck in the rear by an FJ with a big Warn bumper and winch doing 45 mph. That vehicle would NOT absorb as much energy as 2010 Acura TL. Ironically, the probability of injuries would be greater in Olds than in the Acura with the exact same impact.

Conversely, having a big heavy bumper on your FJ, in fact, increases our risk of injury because we're eliminating a bit of the "crumpability" of our vehicles, causing the structure to have less ability to absorb impact energy, even though I'm sure it's a slight amount. Q x Y = 1.28967 of critical mass... just kidding :lol:

that's why the next mod for some of the companies should be a CHAFF canister..


CHAFF is a radar countermeasure in which aircraft or other targets spread a cloud of small, thin pieces of aluminium, metallised glass fibre or plastic, which either appears as a cluster of secondary targets on radar screens or swamps the screen with multiple returns.


So this should cause the guidance system of the missile (human driver) to be attracted to the CHAFF. This is a good countermeasure to prevent missile impact.

Lol....
