Hey guys. I have an 06 Grand Prix GXP. I am in need of new front and rear struts. If I go with the factory Bilstein struts, I'm looking at about a 1000 bucks for all of them. Not really wanting to spend that much on factory struts with the car that has 150,000 miles on it. Is there an equivalent to the factory bilsteins (Monroe, KYB, Acdelco, etc)or am I stuck with that only choice? I see all different brands but most are for 16 and 17 inch wheels without FE4 suspension which the car has 18's. Just wondering what you guys are using that wont break the bank. Don't need springs or anything else, just the struts. Part numbers will help but isn't necessary. Thanks.
