2013 SHO, muffler deletes, 255/35/20 for nearly 2 inches less tire diameter(was attempting to maintain traction while effectively reducing drivetrain resistance and lowering overall final drive ratio). Doesn't look terrible. Blew the right turbo, interested in single turbo setup to make the car a little easier to repair. Overall, these are monsters, and I prefer the traction of the dominant fwd section and the lighter weight rear that's really just an assist, as opposed to our rwd biased competitors. Even with the very scary torque steer.
