The 99 cobra suffers from a weak Independent rear suspension, 99 was the first year for IRS on the mustang's and they stopped putting them on the mustangs until the 03 cobra's came out. The IRS is known to snap. I worked on a 99 cobra at work and the guy was like i think the brakes are locked up. Well my friend has a 99 cobra that he bought about a year ago and i went up and done some research on it. I found out about the rear end probs and that the advertised 320 hp was not true. they were recalled but not all were done. i told this kid with the cobra i was like what year is it, he didnt know so i got under the back of it and saw the IRS and told him it was a 99(only year for IRS, except for 03)and i told him that i bet his rearend broke. He didnt believe me so i put up 20 bucks on it without even looking the car over. Sure enough his rearend was shot. This was at 50,000 miles and slick street tires. (shows you how weak they are). They also have a Tremec T5 tranny but they have proved to be weak. So if you guys run up on a cobra just look under the back and see if it has IRS. if it does its either a 99 or 03. you can tell a 03 from a 99 by the bumpers and the rear wing(03 doesnt have a wing just a extended trunk lid) Watch out for the 03 cobras though they come off the showroom floor runnin mid 12's(with the help of the lightning supercharger)
