We are talking online or endurance races aren't we? Then you are just ruining the tires. You would want to be more gentle with the throttle out of the corners. A common mistake is to just floor it out of the corners because the rear end don't spin out like in a RWD car, so you can do it. But you will waste your tires completely. A way to reduce the problem is to put stickier tires on it. Normally hard tires will last longer then soft tires, but if you can get rid of the wheelspin out of the corners with soft tires you can in some cases get them to last longer then the harder tires.
So what i suggest is that you just put some better tires on it, and/or a LSD and configure it so you can stop the inside wheel of spinning out in the corners.
