Clunking in the back and front after new suspension

[IWannaBMW]

So last night at 1 am, we took my car out for a test drive after installing H & R touring cup kit on it from tire rack. Car is very tight, responsive, worth every penny IMO. But when i go over slight bumps it clunks in the back and the front a little. Sounds like something is not tightened up. SO i checked the rear shock mounts, and the bolt was tight, i mean it was turning the rubber bushing under it, so i figured that's good.


As far as the front goes, once we installed the springs we used an impact to tighten the strut bearing nut, we tried putting a little more torque on it once the car was on the ground but it just spun the shock, so we left it alone.

I've read it could be the sway bar links in the back. I dunno about the front. The car got new control arms, bushings, tie rod ends, and sway bar links back in February.


What could it be? Should i get hollow sockets so i can stop the shock from spinning and tighten the bearing nut a little more?

you didn't really tighten the struts with an impact gun...right?

^^ or do you mean torque wrench?

Not tighten them just get them on there good n tight while the strut was off, i didn't torque them to any specific number or anything

the impact gun will ruin a strut if the gun spins the shaft. What struts also? I know there were some Koni which rattled.

It's a h & r strut that came with the springs. How does it ruin it?
