By "bilsteins from an GXP" do you mean the front? By "stock springs" do you mean the stock front GXP springs? Some specificity is helpful. If this is what you mean, then yes, of course a V8 car strut/spring combo will raise the ride height in a V6 car.

Interesting point about rebuilding the Konis. The logistics of the process are not that appealing, however. Pull the struts, have a carcass of a car sitting at the suspension shop, wait how long for Koni plus shipping both directions?

Part number, specs, and/or link for Vogtland springs for the 2001 GTP? Is the GMPP spring and Koni strut combo still available? Part numbers or link? Similar info for SSC springs?
What I meant about stock springs was stock springs from a 97-03 GP. From what I recall reading on here the GXP struts and OEM springs raised the car quite a bit. You will have to search and see if those photos are still around.

The KYB's as far as I recall are 10% stiffer than the OEM struts. I never used Monroe or Gabriel struts. KYB's excel g's are decent for someone looking to stay with the stock height.

GMPP lowering kit have gone the way of the dinosaur. Vogltnad springs are as close as you can get to the GMPP lowering springs. Drops the car about an 1" or less. My brother runs the KYB AGX and vogtland set up and it's close to the GMPP set up.

Just get yourself some OEM replacement springs. I believe moog makes some. Pair that with some KYB excel g's and call it a day. KYB also sells a complete spring/strut combo as well.
