Different between circle and half circle..

[Black95Cam]

So Im looking to buy a strut bar and doing some research right now. Found a SPW strut bar on ebay for around $45 USD and an another one on http://www.andysautosport.com for less as refer by someone on TN. And the one on the http://www.andysautosport.com seem like the strut bar is half of circle on where you bolt to the strut mounts. And the one ebay has the full circle. Are there any difference to which is full or half circle?

Having a full circle doesn't make a strut tower bar stronger than one with a half circle.

As the bar is being strained, the stress concentrations will be at these areas:

- on the bolts connecting the middle bar to the brackets,
- on points where the bolts touch the bracket,
- the points where the upright plates are welded to the circular brackets,
- on the strut towers, the two inner bolts will have moderate stress concentrations.

Because the third bolt is part of the system, there will be a stress concentration at that point, but the magnitude of that stress isn't significant compared to the magnitudes elsewhere.

For example, cars that come with stock strut tower bars are mostly bolted using only the 2 inner bolts.

Hope this helps.

-.- Now that this has come up, I wanna model a strut tower bar in AutoCAD and run some analysis.
