tubular front crash support
I typed a long thread and my laptop decided to take a dump, so this one will be short.
Wanted someone to build me a tubular front crash support and found a forum member "unobtanium" who does some awesome stuff and voila! Purposes are to allow as much airflow as possible to the radiator/ intercooler heat exchanger WITHOUT sacrificing on safety, infact this 2 inch tubular .120" wall 4130 Chromemoly crash support is superior in strength compared to the factory part. Not sure on the weight differences however?

Yes sir, that sure does look slick. Definitely frees up some area. It being made out of chromoly steel, should definitely be lighter than the factory piece, I would think.

Wouldn't the front fascia still block the area uncovered by the new crash bar? I don't see it making much, if any, difference. Please let us know if it does.

First time I had the bumper off of my car. Nice and easy. Building one of these for my turbo build guaranteed. Makes so much room in there.

Sorry guys, not a sales thread, and I'm not a sponsor.
Just chimed in because I got sent a link. Glad you like them though.

To answer the earlier questions on weight...
The factory front crash bar weighs 14.8lbs. The 2"4130 bar weighs 9.8lbs, and the 1.625"4130 bar weighs 6.25lbs. The 1.25"4130 (smallest I would go while maintaining any measure of safety) weighs 4.9 lbs. Cheers, Chris

Just my thoughts here, and I am sure the new part will provide better air flow but, the original GM part is made of a material closer to spring steel than it is to mild steel and the reason is to provide crash resistance. Your tube will kink in a collision and fold up. GM is using more and more of this special steel in the cars to provide more strength and less weight compared to the heavier material required to provide the same protection. I found some steel in the car that I could not cut with a reciprocating air saw. It just took the teeth right off the blade. Not minimizing your accomplishment, just want to start some thought amongst those who think this is the way to go in Lew of safety. Exclusive use on the drag strip is one thing, but to drive on the street is another. Again just my thoughts and congrats on being very inventive.

I agree 100% that doing this mod is off-road only, but it will save weight and still offer a degree of protection not available without the bar there at all. The airflow advantage could be quite large also, so as usual it is a calculated trade-off. the 2"bar shown clearcoated would not bend in the event of a collision as it's cross section, density, and strength far exceed any factory pieces on a vehicle. A tree or concrete barrier is a different story. It will exceed the factory bending strength without question.

Rear bar weighs 27lbs factory, new tubular one weighs under 5lbs.
Total savings if front and back are swapped of 32lbs.
