Front crash bar- Is it really needed??

[Ange]

I mean for safety.

Our cars has a long ass front with a big ass block. Probably way better crash safety than most cars even without the crash bar. I deleted min because I want to remove as much weight from the front of this car as possible since it's front heavy.

Can't imagine the alu crash bar does that much difference.

my dad pointed out for me that it's also there for stiffness. That's the only reason I could see it being worth saving it for.

Opinions?

Stiffness? They aren't even solid mounted to the frame rails. They are there because insurance companies have made the auto makers adopt the 5mph bumper system. It keeps damage to a minimum under 5mph. It is not a safety feature.

good point. probably right that it's mostly for smaller impact to protect the body from damage.

You sure about the stiffness thing though? it's mounted to the dampers which are bolted to the frame. Should keep the frame from twisting in my mind..

It is not a safety feature.

Yes it is. It's a box girder resting on pins. In the event of a crash the frame rails act like springs. It couples them on frontal impact and also aids in preventing singular torsion on one corner. More than likely it also halves impact intrustion distance on the crumple zones at speed. If you hit a tree or pole at speed and you split the uprights how much further could the impact intrude?

Ever seen lawdoggs hill climb crash where he hit a tree? He likely escaped rather serious injury due to the tortional resistance of the crash bar. The front end never twisted and the drivers side of the vehicle remained in-tact. The crashbar was able to redistribute some of the axial loads off the passenger side and transfer to the drivers side.

Please excuse the shitty pictures. As I said, this was almost 10 years ago and this was probably a 2MP camera at best.











Without the crash bar the ENTIRE core support would have been pushed into the radiator and engine causing significantly more damage than what it ended up with.

yes /thread

Excellent logic you used there.

[Tensecs2fame]

Excellent logic you used there.

Yeah my logic is, Mitsubishi engineered these cars for safety. There's a reason why many owners walk away from bad crashes and rollovers. To get rid of the crash bars without a full roll cage is just fucking retarded. If its something aesthetic on an old classic that might be another story but most 3/s owners use their cars every day. Is that logical enough for you? A retarded thread deserves a retarded answer.

look at the design of the dampers, how the bolts are all inline (no triangulation). the crash bar provides NO chassis stiffening.

A thick front mount will work as a crash bar!
