Means I've always had street cars, and distance to drive them, I haven't ran 4.88's on the street. Steepest I've ran on the streets is 4.30's. I bought a sure-grip 4.56 but I sold them before ever trying them. I don't need to install 4.88's and a 5200 stall, I have friends that run them and see their results. Of course, pure drag cars.
