Yep, what he said, in addition buy the UPR K member coilover kit to really lighten the front up and disconnect the front sway bar on track days. If you are serious about drag racing and want the very best times you will also want to look at swapping to a 4R70W with a good aftermarket stall converter and a J-mod. Swapping to an auto on a New Edge is stupid easy.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
