I keep hearing a clunk noise from my front struts when I hit a bump. When I am driving on decent pavement there is no noise. It only happens when I hit a bump. I don't think it is the struts being blown. I am wondering if my sway bar is hitting on something. The car is lowered on H&R suspension. Any info would be of help considering I am new to the Porsche world. Thank you!

 

Is the H&R install new? Could be a broken spring, broken sway bar drop link etc, I've seen both, specifically with H&R spings.

 

Which side? Could be a strut, but it could also be a stabilizer or control arm.

Once you identify which side the noise is coming from, put it on some jack stands and have a look. The nice thing about suspension is that issues are generally pretty visible.

 

Its both fronts. The previous owner said the struts are still fairly new. I think I am just going to buy all four H&R cup struts and spring set-up and get the sway bar and end links with it. I have been working on cars since I was 13 and even worked in a few shops but, I have never worked on a Porsche like this. Only a 944, so I want to find a torque spec sheet for all the bolts

 

What is the best strut and spring set up for these cars. I had H&R in my BMW and they where amazing! But, I dont know if there is a better set up for these cars.
