Although Imitation is the sincerest form of flattery we were very much taken aback at the new line of rear braces being sold. We all know the name of them so we won't bother going there. These are a vastly inferior product in terms of strength and design. The only claim to fame they seem to have is the erroneous assumption that not drilling a hole in your car is a good thing....

I will address the few pertinent points about this matter then leave the decision to you folks. BMW owners are by far some of the most well informed and bright car owners in the world and are not prone to believing bogus information when shown the facts....

1) Drilling holes in your Shock Towers to mount the Rear Brace will cause your car to rust apart.
    Not True. Using Silicone sealer or Zinc Chromate to coat the hole when installing the hardware will prevent this     from happening. Also as most of you DO NOT use your cars in Rain and Snow it is really a Non-Issue at all.

2) Clamping the brace to the Tower is as strong as bolting it in.
    Lets face it folks. There is NO WAY it has anywhere near the strength of our design. You have a 30# battery     being held in place by this parts and you are trying to give extra strength to the shock towers and the tub. This can     only be accomplished by a proper Triangulated design that is held RIGID in the chassis. This is only accomplished     by making the brace "As One" with the car. This can be done by bolting securely in the vertical and horizontal     plane or by welding. Many of our Rear braces have been welded in and that is an excellent method althoug not     something everyone has access to and of course it does make it difficult to remove again (But why would you     want to ?)

3) Quality of the Installation kit.
    Our installtion kit is the most complete and high quality kit with top quality cable and hardware to finish the     installation and hold the battery firmly in place regardless of use...

4) It is easier to Install than jacking the car up and drilling holes.
     Okay...You have me there....There is nothing we can do about that. The bottom line is to get the strength needed     to stiffen the chassis as well as the safety and strength needed to hold a 30# battery in place in case of an     accident or other impact...(And believe me we have seen the aftermath of accidents where the battery was not     securely held in place. Not pretty...) The only way to do this is to bolt it in or weld it in place. We can understand if     you do not want to do that and unfortunately we cannot and will not compromise the strength of the design for     convenience.
