Lowering springs 05 LaCrosse comaptibility?

[The BetterBuicks]

Hi

 

Does anyone know if the Impalas or Grand Prixs suspension (specifically coil springs) are comapatible with 05 LaCrosse from the same time period? I want to lower my car about 1.5- 2" and I can find nothing on the web about lowering 05-09 LaCrosses. I am also running 18" wheels with 245/45/18 tires and of course don't want any rub. What's the lowest I can go?

 

Thanks anyone with any info that can help me out.

Anything for third gen Grand Prixs and Impalas would work fine. No idea about rubbing. The drop really isn't the problem. 1.5-2" isn't very much. Many of us, including myself, have run 4 inches no problem. It would depend on your wheel and tire package.
