I am not sure if the info is correct here but the Z4M is one of the most rigid production car out there. http://forums.bimmerforums.com/forum....php?t=1725881 Either way, for a few hundred bucks i might install it on my Z4MC for the pimp and placebo affects |

Hey guys!
I am going to make this short and sweet since the snow storm this weekend knocked out our Internet/ power. So I am reduced to my iPhone. There were some questions before in regards to price. As stated in the first post retail will be very close to the e46 race brace. The e46 race brace goes for $315 so expect something in the ball park of that price. As soon as I have an exact price I will let everyone know. Although I really like the oem brace, the reason I always wanted this brace is due the cracking issues I have read about when the oem brace is on a hard driven car. Due to the oem brace's base plates being a cast part they simply do not have the same material strength at the RE brace. If you search the Bimmer forums track section or m3 forum you can find multiple instances of this happening.

In relation to the fact that it takes 32,000Nm of force to deflect the chassis 1 degrees, how does that 0.026mm of deflection compare in the overall picture?

If the whole structure was as stiff in all directions as the strut bar (which we are only looking at for axial stiffness, as it is quite weak in other directions), then we would have an equivalent stiffness of 340,000Nm. The problem is that the strut bar is just transferring load from one strut tower to the other, so has a much more limited effect on overall stiffness - this is analogous to joining two mounds of jello with a popsicle stick, the jello doesn't become appreciably stiffer overall. |

now thats whats im talking about!!! Get rid of the 2 hinge sections and your really talking here, bracing both top and bottom sections together rigidly would make a decent difference :-) the only problem i see with that is the 2 hinge pieces probably render this useless, make that one solid bar and you'd have one of the best strut braces ive seen....

You are probably right but I cannot say definitively since there was no solid 4 point bar to compare. But, hinge or not, 4 points are bolted down and the X piece is still going to keep all corners flexed out. It's also solid on top (no hinge at strut tower), which, at least in the S2K community, was uncommon.
The S2K is very stiff in front but I found that this bar helped with steering turn in and response. Other bars (I had a Cusco) were nothing but show. Cheers |

S2k bar looks awesome. Looks like you can remove the X bar, and just leave it as a regular strut if you so chose.
