Where the Autoexe lower arm bar ties in, in the front seems pretty simple but from the pics available I cant seem to figure out how the rear brace section of the autoexe lower arm bar works. If anyone can let me know where it ties in and share their opinions of this peice it would be greatly appreciated.

Thanks,

I am looking at an article about the FC Auto-X bar in RX-7 Magazine #016 from 2002.

The rear braces are 4 pieces all together (2 for each side) consisting of a short tubular brace and a large triangulated brace per side.

The large triangular brace mounts-

To the chassis at the bottom of the front subframe mount (the giant stud) and connects forward to the chassis floor (making one side of the triangle)

It mounts to the rear subframe at the "Y" pipe hanger mounts (making the 2 remaining sides). The piece angling from the frontmost of the chassis to chassis side to the subframe is a square tube the rest is reinforced plates.

The small tube braces-

From outward trailing arm pivot (the fixed pivot) inward to top of the floating trailing arm pivot. It is two plates the pivot bolts go through connected by a tube section.

The traingular braces would eliminate side to side and front to back movement of the subframe, but allow for the up and down movement (so sublink camber rod would work). There would definitely be some noise/vibration transmitted from subframe to chassis.

The tubular pieces reinforce the trailing arm pivots for more precise geometry and less binding.

I am very interested in trying the Auto-X braces myself!
