had these on for a couple of weeks now.....not happy the car seems to be very slightly bouncing all the time.

Can I ask how much you have had the car lowered by? Also do you have any form of roll centre correction? This might affect the bouncing you are experiencing.

Also what tyres and pressures are you running and do you know the spring rates you are running?

Falken 452,..33 psi all round 18" wheels
as for the other questions i havent got a clue.

just been for a ride in Richie001 sti with a similar set up.Its put my mind at rest,the Bilsteins give a firm ride but very good in the corners.

Glad to hear you are warming to them - I'm thinking of getting the same setup on my STI... Either them or the KWs cant seem to make up my mind at the moment.
