The long trail version of V2 has more agressive knuckle add-on design that offers more jacking and even faster self-steer. However this setup makes the car snappier and a little less predictable, which in turn requires top level driving skill and ability to adapt to a new setup. Other than that the long trail version of V2 has the same fearures as standard trail V2 such as the ability to adjust the ackermann angle (from the knuckle add-on) and also the caster (from the top mount). These new features make adjustment convenient and handy. NB The V2 kit is suitable for both standard models and M3.
