I found it to be low as well. If definitely helps on the track! At our previoys local event on Dec 14th, I ran the stc6 for the first two rounds and experienced no traction rolling, but had a few close calls. I switched to the GX for the 3rd round and traction rolled a few times, and also crashed a couple of times due to the GX turning in so abrubtly. I switched back to the stc6 for round 4 and the traction rolling and crashing went away. Amazing how much of a difference bodies make!
