Excellent quality.

A little tough to install, but well worth the effort.

Didn’t work for me. Customer service very professional.

I had issues on fitment with two set of control arms I got from them. Not going to bash them on here but I’d definitely give your parts a look over before install(with any parts of course) I kept some things I could use and sent the rest back (waiting on second refund) anyway, defects happen mistakes happen, and they’ve been making an effort to get me taken care of even though I’ve been more than unprofessional, unpleasant, and downright disrespectful to their customer service team.

Great control arms

So I ordered some control arms from rockauto and they did not fit my 93 NA. It kept hitting the coilovers. I decided to just use this opportunity as an excuse to upgrade to these control arms instead. I've only used them for a week or two but they've been phenomenal. I'm a big fan of the grease fitting so i can just add more grease and hopefully prolong the life of the ball joint. I definitely recommend these control arms.

Lots of clearance over coilovers and look very tidy. Absolute quality part

Upper Control Arm

Like many customer that come to V8roadsters, our main concerns is perhaps the added wight to the front end of our Miata's. The upper control arm I got were much lighter and quite frankly better looking than OEM(Not that I will see them that often). Going to purchase the front lower control arm next to give my miata the ultimate support. CHEERS!
