Replacing struts and coil springs - Saab 9-3 '99

Hi all,

I have to replace the front coil springs on my '99 9-3. One broke and I always changed them in pairs.

I am considering replacing the strut inserts as well and here's the question:

Can I pair up Bilstein HD (heavy duty) strut inserts with standard OEM (white, white) coil springs?

Or do I have to go with the standard OEM struts as well?

Looking at the Bilstein HD struts, they look way more sturdy than the standard Saab stuff.

Cheers, Ben
