Depends what you value the most, you could try to find more traction with suspension and tires.
What gearing needed for performance wise is to get it into the powerband at most mph, you want to be able to spend as much time in the top 10% of the power curve looks like about 4200 rpm and up (4000-6000rpm) in a full throttle run, of course it's also a street car so compromises could be made.
But after spending all that money I wouldn't want to get it so it's hard to spend much time over 4000 rpm when I want kind of makes the engine a little pointless.
