It is all about how much torque is put down at the rear wheels during the launch. Gear ratios and the shape of the power curve are big players here. The S55 has tons of torque low in the RPM band and the F8X has a stupid short 1st gear overall ratio (especially DCT).
Eye balling from the manufacturer power charts, a DCT F8X puts down close to twice the wheel torque in 1st gear at 10mph than a 6MT Stingray (~6755 vs ~3555 lb-ft). Even at peak torque, the M4 trumps the Stingray with over 40% more torque at the wheels in 1st gear (~6755 vs ~4725 lb-ft). No wonder the F8X overburdens its rear tires when launching.
IMO, a key to the launch traction issues with the F8X lies with the gear ratios.
