Hey guys, been doing a little research on here and cant find a definitive answer, but what are our strut bar options? I believe the stock bar is #15245609 for $141.54 at gmpartsdirect. They also have one listed, #25773253 for $45.41. What's the difference? I also read that the LS2 bar will fit, but I don't know the part #. TIA for the help. Oh, also running the ice-olator, if that makes a difference in clearance options. Not looking to remove the engine cover or hood insulator either.
