Multiplying the engine's torque by the primary ratio of 1.925 and the final drive ratio of 2.688, you get 5.174. Even with the 6th gear ratio of .964, you still have 5 times the torque at the rear wheel that you have at the engine. Assuming you lost 10% of that to friction, you have about 225 lb-ft at the wheel. With a tire radius of about 1.13 feet, you get a maximum of 199 lbs of driving force at the tire in 6th gear, and a lot more in lower gears.
This means it's pretty easy to overcome tire friction with throttle when leaned over in a turn!
