Simple Glitches

At performance shop install upgrade packages in number order.(Example: Turbo 2,1,3,2,1,3 would mean install turbo performance packages 2 then 1 then 3, ext. IN ORDER! (Note: example is not a real glitch)
1. Suspenshin - 1,2,3,1,2,1,3.
3. Weight - 2,3,1
2. Tires - 3,2,1,2,1,2,3.
4. Tires - 2,1,3
5. Tires - 3,1,2,1,3
Note: you can only put one of the three tire glitches on a car. Just figure out which one you like more and use it more often. I dont think they are too much different, but still. Also note that the suspenshin and tire glitches mostly improve handling, the weight glitch emproves acceleration and handling.
The simple glitches only improve your car by a small amount. There are other ones that make a huge difference, but take a long time to do. Its up to you weather or not its worth the time to do, but they do improve your car a lot. All the bigger glitches I know i'll post below.
