Hi all my car is a 1998 saloon and i am a little unhappy about the way the car feels when being driven a friend suggested that it may be a bit light at the rear and that some weight may help, i put in about 60kg and sure enough it was much better,the question is how can i make the car feel as though i have a boot full without actually filling the boot,i have thought that keeping the diesel tank full would help but any ideas ??
