suspension knocks on road holes and make noises

[chmigi]

i have a 205 55 16'' ET38 7,5J rims and tyres on my xedos... but there's so much noises(clap... clap) when i driving on humpy roads or when i pass train railroads
i've changed whole suspension rubbers(selenia-bush) last year(05/2009)... some of parts have been from Kia Clarus suspension
so... there's almost new whole suspension but the car makes claping noises

some mechanics told me that I can try to replace rubber mountings

in the shock absorbers but i can't know where to buy it and from what car do they fit my xedos?

PS
gear mounting fits from mazda 626 GF 1997 (see pic 39-040A)

what suspension (front or rear) makes this claping noise?
maybe wrong offset (38)?

[chmigi]

both suspensions makes claping noises
what's wrong with the offset... i know that serial rim is about 50 but I buy that wheels with ET38 together with the car
neither tyre does not tear fender if you think so...

i saw on threads that some of people changed rear rubber mountings, it fits from mazda 626 GE
so do they turn down noises from the rear suspension after replace a mountings?

[birdhouse]

if this rubber mountings are rotten, maybe they can make some noise on rough way, but it's not authentic

[chmigi]

yes of course, like i said... some mechanics told me that i can try to replace those rubber mountings
so... rear mountings fits from 626 GE, what about front mountings... is there any fit from another car
seems like KIA Clarus don't fit, xedos have 6 screws and clarus have 4:
