Car was running strong all day & was running consistent high 12's. The track was hooking like a SOB and then on my 10th run of the day, it happened. Launched 5 feet & then the car go no more. I broke a half shaft. This is a common problem with Cobras as they are not made for drag racing...especially 99's. Well, I always look at the positive side of things. This gives me the chance to upgrade my IRS!!! She is in the shop getting an IRS from an '04 cobra
