The Mini mantis kit is the most affordable angle option for the 370Z/G37, giving the chassis around 58 degrees of angle, with zero Ackerman. (Other Ackerman options are available)
The kit quickens the steering ratio by relocating the tie-rod pickup point on the knuckle, perfecting your bump steer and allowing for a ton of angle and is fabricated using high strength alloy steel.
The install is 1-2 hours maximum and requires some minor grinding/cutting.
The kit will come powder coated silver, with all required hardware
