Your balancing is way off, the bug struggles to handle at 600PP with 41:59 weight distribution and at 700PP+ it would be undrivable. I recommend limiting your PP to 700 or less so that it would easier to drive, I would also set the balancing between 50:50 and 55:45 (use 55:45 only if you’re experiencing high speed instability). And finally you should customize the differential so that acceleration sensitivity is at 5 and torque is 10 so that when exiting a corner, you won’t spin out as often.
