RE: Is the 2003 Cobra Terminator the king of the street?
the problem with IRS isnt unique to the cobra...its an issue of all cars with IRS.
take for instance when someone is doing a burnout. what is happening when you do a burnout is that the tires are overpowering the suspension and lifting just enough for them to spin. some cars, such as the mirada put a "differential snubber", which attatches to the underside of the floor and when the diff. lifts away from the ground, it hits the rubber snubber, forcing it back down. with IRS, there is no way to prevent the tires from lifting under hard throttle, so instead of the tires trying to turn and being forced down by the suspension/snuuber/weight of the rear assembly, they move up and down much more freely, and make it much harder to launch.
IRS is great for cornering, because when i go into a turn with the mirada and the body leans, the rear axle will lean with it, which means that the traction surface of the tire is also on a angle, thus not making full contact, lessening the traction. however, with IRS as the car leans, the tires move independant of each of other, allowing them to keep more contact to the road. however, from a dead stop, launching is hard because there is too much "give" to each of the rear wheels.
