Oh wow a slow4v sighting lol. I'm guessing you mean the cheap ones are junk because a good set of control arms is one of the best things you can do. I know you had issues with the SR arms breaking. SVE is LRS's "SR" brand and are likely the same exact control arms.
2000 Mustang GT Steeda #0048 34k miles. 99 Cobra 4V swapped, FTBR IRS swapped, exhaust, tuned by James Gordon.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
