If you are going to run a 90" wheel base car, you have tIo have an IRS. Their is not enough room for a drive line to work correctly, and binding of the splines is a real problem for a live axle. That is why we went to a 94 1/2" wheelbase we can run both effectively We much prefer the live axle ease of maintenance adjustability durability and E brakes that works and they don't brake and flip the car and can be made to pule over a G on the track consistently. We see a lot of cars at the track and the number one failure we see is the independent jag or 8.8 If you think this is incorrect go to a Shelby event at you local track and pay attention.
