Does anyone offer a slightly longer front tie rod arm for the steering? I'm not so comfortable with the amount of threads I've got of engagement.

 

Seem to recall a drift group buy on here a long time ago for them, maybe in the archives?

If you know someone with a lathe, very simple job, extensions here are about 1 1/4" long...wouldn't have thought you need them unless the subframe is modified.

 

Not sure if this will help, but nonetheless, Rotaryengine.com sells tie-rod end link that are extended in length for lowered subframes/moved steering racks. I believe this would add length to the end of your arms. You could give them a call and see if they'll sell you a set. They use them as "spindle correction" on their 20b kit.
