The other is corner speed. If you have too much weight in the rear it will want to swap ends (like the hammer) and slow the car in corners, reducing corner speed. A forward weight bias increases and maintains corner speed.

If you're having issues with any vehicle not flying consistently in the air, it is usually remedied with setup. SC is a special case since they don't allow rear wings, but the same principles apply. Suspension and springs make more of a difference in those conditions and once you find the right combination, you get faster cornering with consistent jump handling.
