The "clunk" is from the front strut(s). Not lowered. My guess is that the new struts have less than 20 k miles on them. The dip was a decent sized one at an intersection, one you should slow down for. I had no others in the car with me. Sounds like our friend from Bahrain has the same issue with his new strutmaster conversion. I think I'll just check to see if all bolts are tight and live with it. At least I won't have to worry about airbag problems.
