i run the losi front uprights with the AE steering knuckles, i have been pleased the fit and the performance. try the 4 degree losi upright, standard AE steering knuckle with 0 degree kick-up. that's what i've been running in Knoxville all season. a lot of guys there are running the 4 degree with 2 degrees kick-up.

you can also try the losi steering knuckle but be prepared to adjust the toe and radio trim, you'll gain about 3 degree's toe out on each side with the losi knuckle.
