A year or so back I had a '87 WS6/GTA, t-top, auto car. The bitch ran 15 flats in the 1/4 but around corners, it would sling its fatass around and book it. I just never drove a bonestock (engine, trans, susp.) GT. I heard when they first were produced they did pretty well around corners and even better on the straight. But I never had the privlage. I know from the factory them bitch's sit 4x4 status!
