I run down at GLARC and the X3 is just as competitive as the Serpent when set up correctly. I run a serpent but give my 2 thumbs up to the x3 also since several guys are running it and winning with it. Plus customer service from OFNA is great. I buy stuff all the time from nitrohouse and they always run great specials. I am just glad to see the GT class growing and growing. I do more off road racing but love GT and it doesn't break the bank.
