There is nothing wrong with hollow. They are lighter and it is fully possible that they are stronger.... Many major brands are hollow (Hotchkis, Nismo, Cusco, etc.).
From Hotchkis:
Now, many misconceptions are floating around about the hollow bar designs. One major one is: that a solid bar is stiffer than a hollow one. This is only partially correct. If a solid bar and a hollow one of the same diameter are compared, then the solid bar is stiffer than the hollow version. By increasing the outer diameter of the hollow bar, and fine-tuning the wall thickness, you can yield the same performance while reducing weight. How many racing designers try to cut every ounce out of the chassis? They all do! Reducing weight acts like adding horsepower.
Another expressed concern is the durability of the part when using a hollow bar. Under the same loading, a properly designed hollow bar will see virtually the same stress levels that a solid bar does, yet provide the equivalent handling performance or improve upon it.

Whiteline basically disagrees with the above saying that hollow bars are more expensive, harder to make, and don't save much weight.

Basically, take your pick.... But, don't be afraid of the hollow bars....

yea, I actually put my physics mind to work which is why I said I guess it depends on how hollow it is... the shape itself is very strong and can hold a lot, but it all depends on design... and in most real racing, weight is regulated anyway, so they don't necessarily cut every single ounce possible... in the end, personal preference and budget will be the ultimate factors

i disagree with the end of this statement for many reasons... some companies just make **** cause they know people will buy them... you KNOW it's true
#6734
I was mostly reffering to the bigger companies. There are a lot of companies that are copying others designs using less quality products. Yes I'm sure there is stuff bein made and bought for no reason. Just go to traders village and u will see a ton of examples

Yeah, I think the moral of the story is buy something reputable, and you should be OK with something like sways. Stillen, Whiteline, Hotchkis, Nismo, Cusco, Motordyne, etc. should all be OK. They are all pretty reputable engineering companies. Go with what you like, or what you can get a deal on. I know some offer more adjustability, but that is about it as far as benefits of certain brands (and for most that probably doesn't matter for most people). Hollow vs. solid does not matter. I would personally go hollow for the minimal weight savings, and that is what I had (Nismo, and I know they worked...).
