What is a strut bar? How does a strut bar work? What forces act on the strut bar through the suspension? A strut bar, or tower bar, connects the top strut towers together, in order to increase the rigidity of a vehicle by allowing both strut towers to react to compression and tensile forces. A strut bar plays a larger role for MacPherson strut vehicles, however it can still be important in vehicles with double wishbones as well for compensating vertical forces. Check out the strut bars from this video at: http://www.redline360.com/ Front Strut: http://www.redline360.com/megan-racing-strut-tower-bar-acura-integra-front-upper-MR-SB-HC8800FU Rear Strut: http://www.redline360.com/megan-racing-strut-tower-bar-acura-integra-rear-upper-MR-SB-HC88RU You may also want to know more about the suspension types discussed in this video.

what are the negatives of a strut bar though?

You've missed something, the most important function of a strut bar is to increase rigidity of the chassis. When you corner or hit a bump, the chassis will compress and bend slightly between the struts, the strut bar is there to minimise the compression, hence improve rigidity.
-
Really disappointed you didn't use a welded strut brace triangulated to the firewall. This is a good explanation of the concept for the layman but you could have gone further by explaining how compliance in those fasteners/threads, how those steel brackets are hilariously cantilevered away from the load path make a two point bar a very very marginal improvement, if any, in the handling dept.

hey jason, love the chanel! long time viewer☺. i have a queston, ive seen alot of different strut bars out there over the years and never ended up buying one but now that im building a track car im in the market for one. my queston is what is the difference between the bars that are hinged at the ends opposed to the solid ridged type that are all welded together as one piece? and what is a better choice? thanks man keep up the videos😀

I could watch your channel all day! I have always enjoyed math and physics, but it makes it so much easier to get into when it is being used to explain something like automotive technology. Keep the great content coming. Also I really like your Integra 👍🏻

They increase cornering horsepower..

2 questions, what does a subframe brace do? and what does a tie bar do? i see these alot whenever it comes to the honda modding scene.
-
So basically, get a strut bar?

Engineering...
Please do a video on traction bars on rear axels... include different styles, reasons for use, and how the work. Looking at either modifying it replacing mine, like to have your input. -
hinge type vs fixed type?

Hey! So you say the friction on the wheel caused by turning will pull the strut down (i.e extending the spring, pulling the strut away from the car's body). BUT wouldn't the weight shift from the turn push down and compress the spring (pushing it into the car's body), thereby cancelling out the first force (and possibly being quite a lot stronger than the force you mention in this video)? I hope this is clear and I would really appreciate an answer if anyone has an idea.

my 96 mustang came from the factory with a strut bar that also connects to the firewall. does it make a difference compared to a basic strut bar?
-
the question people might ask is what's better aluminum bars or steel bars.. I prefer a bar that does not flex n maintains rigidity. . aluminum bars tend to flex n those cheap ones off the net aren't really great either. Came across Ultra Racing(UR) bars years ago and totally worth every penny. They stand by their products, I've seen some tuners crash n I've seen their bars break but I've never seen an UR bar break apart.. I've seen them absorb the impact but I'm yet to see one break.

excellent explanation
-
+Engineering Explained Does adding a strut bar to a car reduce or increase stress on the original chassis? Basically, would it prolong a chassis's structural integrity or the opposite?
-
+Engineering Explained I am thinking about removing mine for weight saving since I only run 1/4 mile.Would doing so harm the car with torque flex? Currently at 600+whp@engineering explained

This and a sway bar would make your bearing hubs last longer ?
-
Thank you very much. This is very helpful and clear.

i love your videos but i wish this one had more information and details on differant kinds of strut bars like whats the difference between ridged one piece bars the hinged type like you showed in your video? theres gotta be a differance, which ones better and why?
