Hey guys, All the reviews online said that I would LOVE this frame rail/butterfly brace thing and I have to say I dont know if I agree? To be clear, the quality of the product is TOP NOTCH and as is ofcourse, FMs customer service. This is not a knock on their product, but more so the theory? Also, to be clear, my MSM had zero issues with the factory fails. They didnt have so much as a ding on them. So perhaps, my MSM wasnt that "loose" to begin with? But to get to the point...I dont feel a damn thing. It feels exactly the same? The only difference I feel is perhaps what I WANT to feel and not so much an actual difference. The hard top still creeks slightly on the driveway, same as before. My ebay DP caused the center section to be mounted as low as possible, but I made no modifications to the brace, and the nuts are as tight as they get across the board. So...what have I missed?  Abe

Im sorry to say that the butterfly brace was designed more for the earlier miatas then for our cars. As the NA/NB version progressed thru the years Mazda reinforced the chasi more and more. The MSM stock is already braced about as well as it can be.

I'm surprised you even managed to fit the brace on an MSM. When I bought the FM Frame Rails years ago I think there was even something mentioned on the page that it wouldn't fit the MSM.
The butterfly brace was designed for early NAs.

What he said. You have essentially mounted the new bracing on top of existing bracing. When I was installing the FM exhaust I had to remove a lot of the existing bracing and was impressed with how much was already there.

Unless I am mistaken, the MSM doesn't have a brace that the factory sport cars didn't also have. So what you're saying is that the rails and the butterfly are useless on a factory sport car. I wish that had been more clear, and I hope this helps someone in the future. Fortunately I have another base NB I can put this butterfly on so it's not a total waste!
I do believe I read plenty of threads of people raving about it on an NB not just an na but perhaps I am mistaken again.

Update: Put the factory sport brace back on and the car actually, in my opinion, feels better than with the butterfly brace. I had to have the butterfly brace on the lowest setting so I dont know if that has anything to do with it, but at least to me, the factory brace being back on feels better.
I drove the car back to back and no other changes were made.
So thats how my MSM will remain. FM Frame Rails + factory sport bracing = good as it gets I suppose.

The downside of the butterfly on cars like ours is that you are taking off a perfectly good factory brace to add the butterfly. I'm sure it would do amazing things to a 25 year old NA6 that is completely open down there but it isn't a good bang for your buck on the MSM. I left the frame rails on my car because I think they do add some value and removing them would leave a bunch of holes in the floor pan but I sold the center section. I do remember reading comments from FM that pretty much agree with what is being said here so it isn't like they are trying to sell snake oil.

Adding a roll bar (NOT a Style Bar) and Frog Arms helps a lot too. Door bars will help too but aren't practical on a DD. For me, this is how I rank my "stiffening" modz: 1. Twin hoop roll bar with built-in torque box (see http://www.ebay.com.au/itm/Mazda-MX5-NA-NB-89-05-Roll-Bar-Twin-Hoop-Torque-Box-Design-Uncoated-/282152911674) - drastically reduces chassis twist (even noticeable during slow-speed turns) 2. Frog Arms - noticeable stiffness on sharp turns and reduced cowl shake driving over corrugated surfaces 3. FM Frame rails - didn't notice any difference while driving but when you use the scissor jack to raise the car, the other wheel on that side gets airborne MUCH earlier so it definitely adds stiffness. My car is so stiff with these modz that when I get both wheels on one side up using a scissor jack at one "corner", I can actually pivot the car across the diagonal from the scissor jack (not recommended). On jack stands, the car also rocks diagonally so I have to use screw-stands rather than pin-stands since the pin-stands don't provide enough adjustability. I love the FM frame rails because it makes switching to track tyres and brake pads MUCH quicker - I use a trolley jack in the middle of the rail and change both tyres+pads at once, much quicker than using the scissor jack.

This is an interesting design! Although shipping to the US from Australia isn't practical, I am still curious: was it easier to install than the traditional roll bar?
