Isn't the top one for a S2000? I've seen the bottom style but the burned center makes no sense to me. Maybe if you wanted to match a burned tail pipe? I don't like it and I love titanium. The end peices look weak and I can't tell if they are aluminum or not. I prefer the clean Cusco (titanium) version with beefy end peices, but everyone has their own taste.

^ yes, you can view it on takakaira's web site. It's about $300 + maybe $50 shipping. I was going to have a custome one made but mine would just have been a round tube and not as nice as the Custco version.

Wonder what it weighs compared to the aluminum ones. Seems like most of the weight is in the strut pieces and not the bar. On the web site, says 570g for the Ti front bar. I weighed my cork sport and it was 3lb 2 ounces. 570g is equal to 1.26 pounds.

Has it really come down to the point that we need to save weight on strut bars?? LOL
Titanium tho...mmm...yummy. As for the burned center...I think they're trying to imitate the titanium exhausts w/ burned tips...(which looks good IMO). Burned center on a strut bar...ehh...not my taste

I don't think its exactly for weight savings. Titanium is stronger than aluminum, so it'd be harder to bend and so on. It'd kinda be like having a full steel strut bar, but at the weight of an aluminum one.

its not that you would bend it per say. but the bar will flex less! a lot less. and its not for the weight savings. Aluminum is actually much LIGHTER than titanium.
density of aluminum: 2700 kg/m3
density of titanium: 4500 kg/m3
density of aluminum: 2700 kg/m3
density of titanium: 4500 kg/m3

the rigidity modulus of titanium is 44/GPa as opposed to 27/Gpa for aluminum. So titanium is about 1.5 times as rigid. However these things don't scale linearly so you would probably need about half as much titanium for the same strenght as an aluminum bar. I think for bars it scales quadratically.

Edit: I think its grade 2 titanium. Either way, if these guys are weighting their aluminum strut bars, and they are heavier than the titanium ones, that pretty much sums it all up right there.

aluminum is not a lot weaker, especially 6061. Even if you needed twice as much aluminum to make a bar as strong as the titanium one, you would only save 20% on weight.
quicky calc:
2units of aluminum * 2700kg/m3 = 5400
1unit of titanium * 4500kg/m3 = 4500
20% weight savings....big whoop. if you wanna trim 1 lb off of your car then lose some weight yourself. but I will state again that the titanium bar is not for weight savings, it is for the rigidity.

I was just simply saying that it will be lighter regardless.-Alex

It wasn't directed solely at you Alex, just other members who would try to justify spending 300+ dollars for a weight savings of 1lb. I mean if you want a titanium bar for the looks/brags thats cool. I personally think it looks good too. But 300 bucks??? i need apex seals
