I think you should just buy the kit you are trying to copy!

The brace is VERY well designed, and more thought went into it's design than you can even imagine.

The brace only cost 180 bucks! Not sure how much your time is worth to you, but it's going to take you much longer to come up with your own brace than the 180 bucks you'll save!

Just buy one, you wont be sorry...

Both design will work and is a matter of preference. Mounting it outwards will enable to you mount the swaybar a bit higher for better swaybar arm angle.

While mounting it on the same locations as the subframe holes will mount the swaybar a bit lower, this also will increase the clearance to the exhaust muffler pipe.

Ideally, you want to have the swaybar brackets mounted as far out and as close to the 90° bend, where the swaybar arm is. A good example is to look at how EF and DA rear bars are mounted. Mounting it this way makes the swaybar more rigid and increasing its effectiveness.

Regards,
Charleston

I think they guy who made both of the kits in the pics above (CivicFerio) might know a thing or two about reinforcing the subframe.

Like he said either way will work. They (a-spec-racing) place the mounts further out on their 32mm hollow sway bar setup and in the stock location on their ITR setup.

Exactly. What a classy guy. He responded to your post, and your trying to design a brace like the one he already made!

Is that reinforcement aluminum? Make it out of steel, its 3 times stiffer. My shop teacher won't allow me to use any aluminum on the suspension cause its not stiff enough. Go with a tubular steel reinforcemenet.

Sorry, but your shop teacher is a moron (most are). Aluminum is plenty strong enough for suspension components, just ask Honda, Porsche, Chevrolet, etc. All of them have Alum suspension parts on production cars.
