Hmm...this is not good, as I was just preparing to buy some Bilstein B4s for my car. I checked the part numbers and they seem to be the right ones.
Gas pressure and damping force should not have anything to do with the ride height unless your car is sitting on the shock bump stops (search Google) - can you check ? If it's the case, the ride should be very stiff in front. In some applications, the stock bump stops have to be trimmed or replaced with shorter ones. Did you receive new bump stops with your new shocks or used the stock ones ?
The other reason is that the replacement shock has the spring seat placed higher than the standard shock, which should be very unlikely unless you received different parts than the ones you asked for. Did you have the chance to compare the two shocks (Bilstein & stock) side by side to see if the placement of spring seats is the same ?
At the rear there are no problems because the spring sits completely independently from the shock.
By the way, how is the ride with the new shocks ?
Let us know how this evolves...
