What is the largest size MT Sportsman S/R should I go with in the rear and still get decent cornering. The setup is an Art Morrison 3 Link for
Pro Touring. However, it will probably never see a track. More of a
Saturday Night Pavement Pounder. The car has been lowered by 2 1/2 inches. I will either go with a 15 or 18 inch rim in the rear. I have 16 inches of width to play with bulgle to bulge in each side.

I am an idiot when it comes to this stuff and I figure I will ask the pros
when it comes to 3rd Gen F-Body stuff. I appreciate the help guys.

Thanks
