How ya doing Billy,eh? Not
How ya doing Billy,eh? Not sure what you were driving. In the U.S. the 2.4L 8 speed comes with a select stick shift and paddle shifters. Why the hell any dealership would change up the wheel size on a 2015 TLX is anybody's guess. The standard wheels, tires and tire ruber compound has been specifically engineered for the car to increase fuel efficiency and handling through reduced deadweight 11.5lb and less tire friction at the road.
Please note grumpy Billy, all accident avoidence electronics can be disabled with the push of a toggle.
What you've discribed, engine noise, brake sticking, etc, can be caused by the car's electronic ride stability setting, leaving the transmission in "Sport" mode( paddle shift to 2nd gear or lower) and, simply not having a sales person in the car that knows the car's systems. Take care and thanks for the lengthy(Book) consumer review.
