There are some dual drop-in tank solutions now that appear to be working well. Both DSX and Katech offer them. Or you can do the DSX aux kit if you desire. Either will work but the in-tank setup is a more "OEM" solution...no need to tap a hole in the tank, and you don't have to worry about running the car hard with a 1/4 tank of fuel and starving the fuel system. Mainly an issue for road course stuff.
