irs ? hate to tell you but if you put the p-arts in right a irs is just as good as the solid axle..for anythign shoirt of a 100 percent dedicated drag racer that runs 700 + rwhp
the irs actualy will hoook better on a radial / street tire as it loads the tires more eveny.
check out the mm@ff street sticki shootout ... the ONLY car that survived without rear end breakage ... a ten second flat 03 cobra with irs.
I blew my differentiaol carrier apart in my car
guess what i have in it now ... a 03 cobra traction lock its the strongest true street stylpe limied slip unit you can get due to the huge cross pin and cabron fiber clutch pack.
