FM Frame Rails/Butterfly Brace
I just installed my Hard Dog roll bar and I also ordered some FM frame rails since I've been wanting to install the butterfly brace I've had sitting around for some time.
After getting the roll bar in, I noticed a really nice difference in the ride quality and how potholes and bumps were less harsh than they were. So now I'm wondering if it's even worth it to install the bracing, since they're advertised to help the stiffness and ride quality. That, and I'm pretty content on the ride now.
I've read the reviews that I found on FM and m.net, and most people seem to agree that having a roll bar is great, but after installing the frame rails and butterfly brace, they noticed that things were even better. But the reviews that basically said, "Noticeable difference, but not huge or worth it" have me wondering.
Anyone here start with a roll bar and then add the bracing? Is it worth it to go ahead and install, or just go ahead and sell the package?

Let me know if you sell the rails, i would buy them off you. I also have a HDACE, i wouldn't mess with the butterfly brace myself due to clearance issues. Keep in mind my height is 12.0 front and 12.25 rear. If i were stock suspension i would add both braces.

I don't think that there will be an issue with clearance either way, they seem to be pretty certain that they've made it well enough to avoid alot of issues, and I don't drag anything on the underside of my car unless it's a really big speed bump or odd driveway. And just in eyeballing things, I don't think there will be a problem.
I have a 3-point strut tower brace that did a really nice job of tightening things up front. So considering that, was the addition of the rails on your car extremely noticeable? Like I said, I'm pretty happy with the handling now, I guess the addition of the bracing in my mind is to help take the rest of the ride harshness away since I do daily drive my car.

Almost everything I've read has said that the frame rails do most of the stiffening and the butterfly brace is mostly unnecessary.
I'm planning on building some frame rails myself and welding them on. Just need to buy some material, and find a welder, and find some time, and wait for it to warm up outside, etc.

Well in all the butterfly braces I've seen locally everyone of them was the lowest point on the car. It's a fine line between getting the exhaust/cat not to rattle and losing ground clearance. You don't think it was just a coincidence that FM changed the ride height on their springs just after releasing the BF brace? My car is very low (not JDM low), I see scrape marks on my FM frame rails from the steep incline on my driveway.

well to answer your question, the AE86's have a problem with a lot of flex in this area, and the boss frog ガッチリ Supports (gacchiri, i guess you can call them fender braces) help a LARGE deal with flex. It made a huge difference on my friends car, so i would say they would definately be a good addition. tuckin99 also makes one of these if you care about weight savings, theirs seems less beefy, but they look exactly the same as Ueo's for the corolla. Boss frog's seems really beefy.

Also, I think my OEM exhaust was lower than my new one, with the factory resonator in it:
And for the record, yes, I already had a rollbar. I noticed a big difference, but since I did the Skip Cannon brace at the same time as the butterfly it's hard to tell what did what.
And whoever it was not running a shock tower brace, you're crazy. Even my old $3 one was awesome, made a huge difference in bumps around corners, and my CD player stopped skipping on bumps in the straights. Seriously.
