Panther

I have a lot of respect for ADS but in all honesty, it's still just a bravo. There's only so much you can do with such a small gearset. I've found that 600 hp is about tops for a X drive and 700hp about max for an XR. Even at those power levels, you'l be replacing gear sets every couple of years.

There's no magic pixie dust in my opinion.
