NFSW Offline : How to edit Menu "Server Settings"

I just wanna know why i can't edit any of Server Settings in drop rates. it's said " One or more drop rate percentage don't add up to 100% " And what is best server settings to drop some rare Performance parts ?

Make sure the drop rates add up to 100%. Like, if you want to make it drop all five types of prizes (IGC/Boost, Powerups, Performance, A/M & Skills) at the same drop rate, it HAS to be 20% for each. Or if you want it to drop more Performance Parts, you need to reduce the percentage of another prize type, or eliminate it completely, before you can increase the performance part drop rate. Of course, you can set the Performance Parts drop rate to 100% and untick all the others, then it will ONLY drop Performance Parts.

If you receive a rarity parts you need to modify or remove some parts. You need to edit the file it.
I modify the XML file through Notepad ++, a useful shortcut to the XML format: Crtl+alt+shift+B

If you want performanceparts winning just gotta set the value to 100% and the rest to 0%

Thanks :D I got it

Oh. Another thing! I want some Drift Trainer or Trainer that can change handling in it. Do you have one of them ?
