Bumpsteer Correction Pt. 1

Working on bumpsteer corrections. Info I found out so far:

Factory outer tie rod specs:

Large Diameter Taper (Dimension B) : .59"
Length (Dimension F) : 3.74"
Right or Left Hand Threads : RH
Rod End Thread (Dimension A) : M12 - 1.25
Small Diameter Taper (Dimension C) : .49"
Stud Thread Size (Dimension E) : M12 - 1.25
Taper Length (Dimension D) : .59"
Thread Type : Female

S13

Large Diameter Taper (Dimension B) : .61"
Length (Dimension F) : 3.94"
Right or Left Hand Threads : RH
Rod End Thread (Dimension A) : M12 - 1.25
Small Diameter Taper (Dimension C) : .51"
Stud Thread Size (Dimension E) : M12 - 1.25
Taper Length (Dimension D) : .63"
Thread Type : Female

AE86

Large Diameter Taper (Dimension B) : .59"
Length (Dimension F) : 3.31"
Right or Left Hand Threads : RH
Rod End Thread (Dimension A) : M14 - 1.5
Small Diameter Taper (Dimension C) : .49"
Stud Thread Size (Dimension E) : M12 x 1.25
Taper Length (Dimension D) : .57" (close enough to not matter)
Thread Type : Female


Looks like I can bastardize S13 ends and use 86 shanks (part that goes into the hub, no idea on technical name).


AE86 uses the same size taper (Dimensions B, C, and D.) and the thread for the crown nut (e), S13 shares the same thread on the rod end (Dimensions A). The S13 threaded end might be a little too long, but that shouldn't be a big deal. Worst case I trim it down.

Now, to find a cheap solution to making these, and not buying sets of both.
