DIN curb weight is the curb weight of the vehicle without extras, plus 90 percent of fuel tank and 75 kgs of the driver.
Weight and how it is balanced significantly affects the benefits of TR. A good portion of a high TR vehicle will be negated if its weight is not optimally distibuted
Increased wheelbase impacts the TR negatively
High TR helps in comfort. It has a positive effect on taming NVH especially on rough roads
Rear folded seats can reduce TR by at least 2000nm/degree
Increased TR does not always translate to better driving dynamics, and can impact them negatively in some cases.
Convertibles usually lose at least 5000nm/degree of TR from the standard body.
