Upgrade
Hmm. I know it's not what you asked, but, I think I might upgrade the steering servo. Image is blurry, but, If that is a futaba S3305 or S3306, I think you would be better off with something that has these specs.
Servo speed: .13 or faster
Servo Torque: 250oz. in. or Higher (stronger)
That servo is either .20 on speed Way Way Way to slow for steering.
Also might be around .15 if the S3305. S3306 has enough torque,but too slow.
S3305 doesn't have enough torque.
This will make the truggy easier to drive especially on a tight track. I you keep the servo, you will have to pre steer your corners in order to compensate for the lack of servo speed.
