Greatgolf7 Report post Posted January 20 Yesterday I test drive a 2007 and 2011 GT500. In the market for a used Shelby. Both were really nice, however I could really tell a difference in handling in the 2011. There must have been a lot of improvements in the suspension beyond the lighter front end. Car was only 12k miles. However under the hood was clean but you can see the aluminum block not looking so pretty. High humidity definitely caused some corrosion. Everything else under the hood was perfect. I know I’ve added some aluminum parts to my 67 and the same thing happened and it’s garaged. What are others experiences and did you do anything to correct it? Thanks Pete Quote Share this post Link to post Share on other sites
