Mantis Angle Kits

Mini, Mild, and Mega – What’s the Difference?

We offer our Mantis angle kits in three versions to match your driving style and build. Whether you’re just getting started or building a full competition car, here’s how each kit compares:

Mini Mantis Kit

Easy upgrade for beginners
The Mini kit was built for drivers who want a bit more steering angle without making major changes to their car. It’s simple, easy to install, and great for learning.

Small increase in steering angle, usually 15 degrees more
Works with almost all OEM components
Great for beginner drivers
Easy and fast installation

If you’re new to drifting or just want to get more out of your car without going overboard, this kit is for you.

Mild Mantis Kit

More angle, stock fenders
The Mild kit gives you a big step up in steering angle while still fitting under stock fenders. It’s a popular choice for grassroots events and clean builds.

Around 60 degrees of angle (chassis dependent)
Track width increases 35–40mm
Works with stock fenders
Simple to set up and drive, but usually replaces the OEM control arms

Best for drivers who want solid angle without needing wide-body or major mods.

Mega Mantis Kit

Maximum angle and performance
The Mega kit is our most aggressive version. It widens the track width significantly and includes a full replacement knuckle with improved geometry, providing you with more control and faster response.

Around 70 degrees of angle (chassis dependent)
Track width increases 65–70mm (per side)
Wide-body or flared fenders are usually required
Includes Full suspension replacement parts (all control arms, knuckles, tierods and camber/caster plates)

Best for competitive drivers or high-grip builds where performance matters most.

Camber Plates

What are the benefits of adding camber plates?

Adding camber plates helps you to adjust your camber and caster beyond the factory range to improve handling.

Tie Rod Upgrade

What are the benefits of adding a tie rod upgrade?

The tie rod upgrade removes the use of your inner tie rod with a rack adaptor and a longer tie rod body. This helps prevent blown out inner tie rods, so you'll never have to change your inners again.

Extended Brake Lines

Why do aftermarket arms require extended brake lines?

Whenever you increase camber or lengthen your control arms the OEM lines are not long enough to reach. When you get more steering angle, the line needs to have more flex in it.

Rack Relocation

What are the benefits of relocating your rack? What is the difference between inline and offset rack spacers?

Offset rack spacers are used if your steering rack is a rear mounted rack and is in the OEM location. It positions the inner tie rod at an offset position from the center line of the rack, giving it a better angle to prevent over centering at high degrees of steering angle. An inline rack adaptor means the ball joint is inline with the steering rack. This is used on all front steering rack cars (like all BMWs) and also on rear rack cars if the rack is relocated (like on Nissan cars). Relocating your rack to be inline is even better than running offset rack spacers because the forces remain inline with the steering rack.
