Are aftermarket "high performance" front sway bar end links worth it?

[pvtdynamite]

Hey everyone! Workin on a full resto/mod build of Darla (my s13 hatch... 93 for those that care). I'm currently stitch/seam welding EVERYTHING. After that I will be working on suspension on a tight budget. I plan on mostly drivin' her on the street so I'm lookin' for maximum GRIP
I have chopped and welded knuckles with 5 lug conversion and z32 brake kit. I also have polyurethane bushings and aftermarket coilovers (I don't wanna say what brand because I don't want u to hate me).
I plan on boxing my LCAs and build my own nismo power brace. I will also be installing a strut tower rod.
My front suspension is in pretty good condition so I have the "if it ain't broke don't "replace" it mentality." The only thing is my end link bushings are fucked.
My question to you is... Should I replace the bushings (if so, factory or polyurethane? Or should I replace the whole end links ( if so what brand?) I would really like to hear from people that have experience with aftermarket set ups but all opinions are welcome... Thanks guys and gals!... Here's a pic of Darla as she sits
