It comes with the outer tie rod and not the inner. Use a S14 ITR cut to 9 & 5/8 inches from the rack surface to the end of the rod.
feel free to get any brand from the local parts store on the cheap
we are currently working on a spherical bearing based ITR but there is no time line on it yet, still manufacturing the sample then testing, then production. It will be a while.
The Z33 inners are shorter than the S14 inners, The Z ones will screw into the outer but you just dont have enough threads to properly adjust everything. Just went threw this with my SAK, picked up some S14 rods cut them and then got everything aligned, you dont have much toe out adjustment with the stock ones though, only got a good 1/16 toe out on mine after the alignment got done. Might get Ikeyas later or just wait for the PSM inners to come out.
Dont use Z33. use S14 tein, local auto parts store stocking brand, any cheap one is fine for now if you are waiting on ours. cut to 9 & 5/8 inch from rack surface to end of ITR
