Ballast

Hello! I logged into iGP and was setting my strategy for today's race when I noticed I had ballast (2 kg) for today. Could you let me know how I got this and how much of a difference it actually makes?

You are slightly slower in qualifying but you should receive more design points than your opponents and this should balance the ballast in race.

Thank you! Will lowering my driver's weight in training help?

You should max your Driver's stamina and weight before you do anything else (atm weight is temporarily turned off, but when it is turned back on if your driver level is too high it will take a lot longer to train the weight off).  Once you have maxed stamina and are minimum weight then focus on training driver abilities and after that mental abilities.
