In another thread I said that Grand Prix GTP's ran an average of 13.6 stock... I looked on the wrong page. Mid 13's is for modded GTP's.. some hitting 12's.. but stock seem to run lower to mid 14's. Sorry... I did find out also that the GTP can take out alot of cars on the 1/8 becuase it is GREAT on the low end... but not so good in the high... If you guys ever race a GTP.. make sure he is going 35-40mph... this is where my car is the slowest... it is almost like a Honda until about 50-55
