You will find an updated utility for N3/NL car editing at www.theuspits.com.
All the functions (move, rake, scale the body, driver and each wheel) that
were available for N3 are now possible for each of the NL cars.
The utility also have a bodyshop function that reduce the number of files
needed to be edited when you are doing a modified car. For purists you can
also change the driver point of view in height if you are doing a kart or a
monster truck.
A complete tutorial is available at :
