Common belief is to get Koni / Eihbach spring combinations front and back.
Alternatively you could use Bilsteins with standard springs. After experiencing both I would say the Bilsteins are better over the Konis as a shock on their own but they are a little bit more expensive about $1000 AUD where as the Konis were $600 AUD (depends where you can get them also - have seen some very good deals on the internet) This is for fronts only - just double it for the backs approx. With labour and parts its about $1650 -$2500.
However alot of people say the Koni Eihbach combination is best as the springs provide the initial hardness and you can adjust the Konis dampers for the ride you want hard or soft.
Ive got the Konis on the front so far without eihbach springs and they are ok. But would like to see what they are like with the Eihbach springs.
Or you can use Bilstein on standard springs. I heard someone say they had Bilsteins with Eihbach springs and they were way too hard. But the Bilsteins on their own are an an amazing shock. Could be all you need.
Either way bilstein or koni are far better than the original setup.
