Wisefab BMW E46 E46M Front Long Trail Drift Angle Lock Kit V2 (WF4601)

The "long trail" version of V2 has more aggressive 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 features 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.

• Higher roll center: Wisefab suspension kit brings the front roll center up on lowered cars, providing higher roll stiffness.
• Revised steering geometry (trail and Ackermann): You could tune your steering geometry either towards positive or negative Ackermann in just a few minutes even at trackside without messing up an alignment.
• Good camber control with high steering angles: With high steering angles the leading wheel will have a positive camber, which is not a positive effect. It reduces the front grip and during turn or flip it creates a contact patch transition from inside edge to outside edge. It is not possible to eliminate it, but with our geometry it has decreased as much as possible.
• Steering jacking control: During drifting, when steering angle is much bigger, jacking is also bigger, even with the same geometry and it could become a problem. We have monitored it and changed the geometry that it doesn’t cause any handling issues.
• Predictable self-alignment control: With certain suspension geometry at high steering angles it could happen that the steering wheel is locking up at the end and driver needs to apply some force to flip it to other side. We know what causes it and have decreased it to minimum, if not eliminated it.
• Adjustable lock-stopper.
• Stronger inner ball joint design over OEM and older Wisefab version.
