Drag Racing Tech - Need launching help LS1 f-body T56

Okay, so I got full tubular rear suspension and sfc, and can only easy launch the car without spinning with 2.1 60ft times. I don't want to destroy my clutch... I have Nittos in the rear, 555Rs which were better than the bfg drs and the m/t drs (those were the worst) . Car is not lowered... stock 10 bolt with 3.42s

Car is making 353whp so anyone in the range with aftermarket suspension and t56, how do you launch?
Thanks

With the 10 bolt in the car you don't... Get a real rear in it now, and put a bias ply tire on it. This topic, has been beaten to death, please do some reading before asking the same question that's already been asked, 100's of times.
