I've spent a short time reviewing some prior threads and I'm now considering three options for rear control arm replacement. All are about the same $. (Ford Racing a bit less). I'm after standard performance, but something that will likely last more than 18K. Looking for opinions. Maybe a great link I missed.

I don't beat on this car. It just turned 18K. No way I was going to let Ford dealership replace these with same garbage. (for 680!) They also charged me additional $40 to tell me huge noise was from "Rear conrol arms shifted on bushings and rubbing on unibody". Car was already up on lift. I called them on it, saying suspension inspection was included in "Works" package I'd already paid for. They said extra charge was for the additional "shaking and measuring"! So, after 12 years of loyally letting them rob me, I'm shopping out work. Thanks!
