Hi, first sorry if my English is bad.
Its many years seen I run RBR ( Before all NGP) and its not easy now.
I found this text
Next, it's the physics' turn. And immediately it's triple caution time! Because VW is an NGP car, you must use the physics.rbz coming with the NGP plugin instead of RBR's original file. (The small yet so important distinction between these two rbz versions is in their physics.lsp files.)
But in RBR...
Put NGP cars in right physics.rbz
