Audi A4 B5 Suspension

can anyone help with my situation...

approx 4 months ago, i purchased a G-MAX suspension kit (springs n shocks)

i had it fitted and it seemed fine, well at least the front suspension is holding up however........

i have had to change the rear shocks 3 times since i purchased it!! :zx11:

i know its nothing faulty, just that g-max suspension for audi just aint good enough...... :o

can anyone recommend what to go for instead, mind its only the rear shocks only i have to change......i have been told koni and eibach are the way forward?? :confused:

thanks guys
