I've been searching through the forums trying to find more information on replacement Front upper control arms and lower control arms since I just learned that the ball joints are not replaceable. I've seen past posts talk about the ones from DORMAN and also from MEVOTECH. I couldn't find any solid data talking about their performance and comparison to OEM besides one thread where some people said they liked them and others said they wouldn't get them again. I was looking into aftermarket options and found 2 companies Nagisa and PartsShopMax. Anyone have any type of solid info or suggestions on what I should do? I have tried looking for used OEM ones but have not had any luck. it's for a 550hp street/auto cross FD. I was planning on going with OEM arms and changing the bushings. A little lost on this so anything helps.

 

This is how i recall replacing the ball joints being done back in the day:

 

Excellent '95 front UCA's and LCA's
Good bushings / boots and tight ball joints.
All my parts may be returned if not satisfied

+1 for Tomsn16 seller!
I have the Nagisa front UCAs, and here is my 3 year review:
First, they are well built, and adjustable. The bad things are...
They have no provisions for the wheel speed ABS sensor wires. Mine are just zip ties to the arms.
I have contact with stock wheels as well as my Fikse 18" wheels close to lock.
You get more camber adjustment from the LCAs than the UCAs.
The Nagisa UCAs have rod ends (heim joints), which have a shorter lifespan than the stock bushings. Racecar.
Eventually, I'll be going back to stock UCAs. I did purchase Moonface (discontinued) LCAs with replaceable ball joints, and I like those as they correct for roll center. My car is lowered, so it helps eliminate bump steer.
Get new or used stock arms and be done. They last a very long time.

 

Fwiw, I just replaced these arms on my Miata. The aftermarket arms from Moog were dimensionally accurate to the stock arms. I've used mevotech arms on my truck and they are working well. I would definitely consider them as a viable option if I couldn't get my hands on OEM.
That said, Tom has good, used, OEM arms so I'd go that way given he has a good reputation for not selling junk.

 

If everything else falls through, Juan at J-Auto is a good guy and set me up.
