87Aerocoupe

Hey folks, Happy New Year, I have a 97 SS that I am upgrading the suspension. I have an S60 rear with relocation brackets, Strano SLP Bilstien shocks with Strano springs, 35mm/25mm sway bars, tubular trailing arms, crossmember mount adj torque arm, adj phb and sfcs. I want to add tubular upper and roto joint lower a-arms, has anyone had issues with them breaking on a daily driver? Also are the boxed lowers with roto joints better for street - daily driver use? Thanks for any opinions and help.
