I recently installed Godspeed mono ss full coilover on my 2014 Lexus is250 f sport. Everything is installed correctly but now I have a weird clunking noise in the rear when I hit bumps on the road. It sounds like it’s about to break in the rear. I double checked everything and all nuts and bolts are tight. Any ideas what the problem could be??

double check the nut on shock tower, make sure it’s tight. If that is tight double check all your nuts and bolts on the spring seat arm. Make sure you back track everything and if that is all bolted down then it’s the quality of the coil over. My coilover makes almost no noise 100% of the time
Make sure the springs are sitting correctly (rotation wise) the top part of the spring where it ends(circled in blue), has to be clocked to the far outside direction of the car. When I first got coilovers installed in my car one of the back side kept making the same noise you're describing, tried everything including re-torquing all the bolts and still made the noise. Turns out the spring was clocked a bit off, undid lower control arm, clocked the spring so the blue circled area is facing outside of the car... noise went away and never returned after driving for 2 years now.
