Mustang Suspension(got traction?)

Does anyone know of a good company that makes a good 4 link setup for a rear axle assembly for a 94 Mustang? I need some serious traction but I would like to know which ones are easiest to install and have proper fit. I don't want to cut the car up too much. Horsepower will be in the 800 horse range and I don't think the upper and lower control arms will stay bolted to the body during a launch. Thank you for your help.
