Terrain, rider weight, riding style, and stock set up are all determining factors. You live in Georgia and that alone should get you to do the suspensions upgrade. If you're around 180-210LBS and ride conservatively you can probably get away with the stock set up if you can get it dialed up. Now if you wanna make it harder for 600 and liter bikes to pass you in the twisties, get the upgrade. If I remember correctly I have 25mm spring and my shock spring is rated for a 240LBS rider. I like my set up on the stiff side. The downside is that you're bike is going to be extremely picky. I can tell when the suspension oil is cold and I struggled when I was running the Pilot Road 3. Something about the carcass of the tires not being able to handle the stiff suspensions.
I would get the front forks internal upgraded, change the shock, increase rear height. You'll be able to lower the front a little since the suspension will be firmer and have a really corner thirty 14R. Add a 55 rear tire to complete the setting and you're golden. I have tried the Q2's and the PR3 in 55 and I'm currently running the Rosso Corsa. The DRC is taller and narrower than the other 2 and falls quicker. Keep us posted!
