Power Steering Tie Rod End Threads

[Alphamacaroon]

I have my Coupe mostly aligned now, but one thing that is bothering me is the lack of thread engagement in the tie rod ends. To get the wheels perfectly parallel, I'm getting ~10 turns on the rod ends from completely loose. Because the rods are finely threaded, it seems like the tie rod isn't sitting in the rod end very far— there is a LOT of extra thread showing on those rods.

Picture for reference:

I think the tie rod extensions that FFR supplied me would help the situation a lot, but FFR said those don't get used on the power steering rack.

Question:

How far, or how many turns would you consider the minimum safe distance for the rod ends to be threaded on? Maybe I'm just being overly cautious? Maybe 10 turns is perfectly normal?

I've checked and checked again, and the suspension and spindle steering arms seem to be installed correctly, but happy to send pictures if something doesn't sound right. Much appreciated!

This question has been asked before and the answer from Factory Five is 1 and 1/2 times the diameter of the outer tie rod threaded section. Looks to me like you're about there, so might be OK. That pretty much aligns with standard engineering practice which, depending on what source you use, is between one and 1-1/2 times the diameter. True you don't use the rack extenders on the PS rack since it's supposed to already have them installed. Hate to just throw parts at it, but if you go to a longer tie rod end you could get more engagement. I've used Moog ES2150RL ends on a couple builds including my Gen 3 Coupe. In addition to being longer, the design allows you to see the end of the inner tie rod so you can see the exact thread engagement. About $20 each. https://static.summitracing.com/global/images/prod/xlarge/mog-es2150rl_xl.jpg?rep=False. If you go that way, suggest also ordering 9.13101G Energy Suspension poly dust boots. A big improvement over the standard rubber ones.

Great advice as usual. Thank you sir!
