BMW's are pretty good bodies. They want to tip a little. They have a lot of downforce. O BTW, when you cut your wing a little mod that I do is The line that they tell you to cut on,Cut about 1/2"-1" inch higher than the line. This will greatley give you more downforce and make the car easier to drive.Also, if your getting the Protoform BMW, In the wheel wells when you cut them out there is a cut out of a square in the middle of the wheel well. Those you cut out after you cut out the body. You take those little squares and glue them on to the sides of your wing. This helps a little too. Hey, its better to have more downfoce then too little.
