I have an 04 gto with irs and the only suspension mods I have are king springs, koni adjustable shocks, and an slp swaybar in the rear. The front suspension is completely stock. I cut consistent 1.6x 60' times with a best of 1.58. I'm pretty happy with those short times considering the irs suspension and weight of my car, but I'm curious how much would installing adustable front struts or coilovers on the front help my short times?
