Does your car have electronically adjustable shock absorbers?
What are the OEM part numbers of your original front and rear springs and your original front and rear shock absorbers?
Which Bilstein B6 and Monroe shock absorbers are correct for your car?
If you contact Bilstein and Monroe directly, maybe they can tell you by reference to your car's VIN number.
Maybe these rear shock absorbers are correct for your car, but you would need to check with Bilstein and Monroe directly?
I can't see any OEM part numbers listed against the Bilstein B6 20-267537 rear shock absorbers, but there's a long list of OEM part numbers shown against the Monroe C1521S rear shock absorbers, as listed below.
Note, that these two rear shock absorbers might not be correct for your car. You would have to check.
I'm not sure Bilstein B6 shock absorbers would be ideal for lowered ride height springs. That's normally Bilstein B8, and Bilstein B8 are not electronically adjustable.
So if you've got electronically adjustable shock absorbers, maybe go for standard ride height springs? You could always select a slightly stiffer standard ride height spring if you are finding your current springs too soft. Perhaps try two weight range stiffer rear springs? Together with top quality shock absorbers such as Bilstein B6 you should notice quick a difference.
Bear in mind, that if you fit difference springs to standard such as lowered ride height springs, the shock absorbers that are correct for your original springs might not be ideal for your different springs.
