This is just compiled from various internet sources including this site, and may contain various errors and bad judgements due to marketing hype ![http://www.my350z.com/forum/images/smilies/smile.gif](http://www.my350z.com/forum/images/smilies/smile.gif) But I just wanted to compare these before I picked one out, and thought others might like to see.

Also, keep in mind that a 34% stiffer might be 134% as stiff or vice versa. Use your best judgement. I used the slash notation for “front / rear”–it’s not fractional.

Let me know of any corrections, and I’ll fix them. PM me and I’ll be able to update faster.

Thanks to everyone below for making corrections and adding new information!

_NOTES_

[1] Prototype size listed for rear bar; corrected with production size  
[2] Corrected measurements  
[3] Possibly listed incorrectly as polyeurethane bushings. They are a yet unknown black substance  
[4] “N-way” adjustable means that asymetrical pairs of holes can be used to achieve in-between adjustments  
[5] I think I got mad at someone else’s website and inadvertently blamed it on yours. Sorry. ![http://www.my350z.com/forum/images/smilies/smile.gif](http://www.my350z.com/forum/images/smilies/smile.gif)
