I have the OE springs front and rear, GT 500 Lca,s, and PH bar. These springs and stuff were pulled with 9800 miles last week. There is a difference in these from base model GT's. Spring rate is different. I can give you exact difference upon request. Its in a drawer or I can get it from my CL ad I put up. I will post Pics in the morning or when I get to Wilmington. Leaving early but takes 2 1/2 hours. Stuff looks and is like new. Local would be great. Looking for best offer. These will not lower a car for those wondering. Just OEM stuff from the Brembo package.
