Seethru. What you should do. Do a trackday or 2 with a bone stock car. With the VDC on. On used up tires. Push the hard as you can. Try to get the rear to step out. Feel what it's like to drive an unrulily car. It's call experience. Then slowly make your changes as you get faster with more track time. If you throw everything at the car all at once. You will have a big hole in your learning. If you make all the changes at once. There is a good chance that you will not get any faster. I've seen guys do one trackday. The next time I see them. They went out a bought a set of JRZ 4 way coil-overs.
Have no idea on how to set them up. And spend the rest of the season trying to figure out why they never got out of the beginner group.
