[QUOTE="351stang, post: 14969494, member: 1355"] [b]Try Airbags and other "old racer" tips[/b] This is a old drag racer trick and is cheap. I don't know why it hasn't caught on with the Cobra crowd. [url]http://www.summitracing.com/parts/air-60797/applications/year/2004/make/ford/model/mustang/submodel/svt-cobra[/url] They're cheap and allow you to adjust to changing track conditions or different tires. Use about 2 PSI more air in the right rear. Try 13 psi LR/15 psi RR to start and play around with it. I'd call Summit to verify that these are 2003-2004 compatible, because I can't remember the PN I bought years ago. Run the schrader valves to the trunk and label them. Be careful not to over inflate with high pressure air. You don't even have to drop the springs to install them. Your burn out doesn't look sufficient.
