I have come to give a suggestion for a good LFS change to the leagues, for example each one can use traction that wants in the car (for example if you want to participate rally with XRT could give me opportunity to equip it like 4x4) another is change of tires.
For example running with XRT with track tires (as has XRR)

Another thing that was important that did not change is bug in the pit's (when we go for example change the tires takes a lot to change tires and do things that in real competitions did not take so long, I'm not talking about repairing car body type damages , I'm talking about simply changing tires that takes a lot of time)
