Any of Takumi_Project.d`s layouts. Always imaginative, and some of them were a real bitch to get round without mangling your car. You`ll find them around somewhere. Sadly, he left here a while back.
X-Roads aka crossroads. It's fantastic with a tail-happy car like the LX4. Can result in close races and a lot of fun. This is my personal favorite because I still keep on racing in there once in a while.
