Hi Charlie,
Are you driving a Track Pack or R model? Coolers are recommended when tech or base models are run at the track- see your Shelby Owners Manual Supplement. Also included in Owners Manual is info on front end alignment settings for the track. Other recommendations depend on what kind of track event you want to do. Beware - FP has pretty much said don't expect more than 8-10 minutes on a hot day in a non-cooled GT 350 before limp mode.
