You asked.. We listened.

Since the debut of our Losi Mini-B Bolt-On Sprint car cage and body, folks have asked us to come out with a carbon fiber chassis similar to that of our late model conversions. We were hesitant, because as-is, the Mini-Sprint class has grown and is relatively affordable if using the Losi Mini-B Pro Roller as a base with a brushless kit. With the Mini-B RTR Brushless, it makes it even more affordable. But, we still got asked constantly. So here it is.. We've been running this at the last several big events and it does very well.

Here are the benefits of the carbon chassis kit:

Utilizes the original HackFab Bolt-On Sprint cage and body (NO NEED TO REBUY)
Improved battery location - left weight bias
The battery is sandwiched in an upright position. The Protek 2s 1100mah is our battery of choice and fits perfect. Other batteries may also fit - the post holes are slotted for some adjustability. The standoffs are 30mm tall, so a 30mm wide battery is ideal.
Sides of the chassis are drilled for optional weight bars to allow easy weight tuning and placement (the actual bars will be available Late March). The kit comes with 3d printed bars if you want to help keep dirt out of the chassis without adding much weight. The bars can also help tune chassis stiffness.
If you don't want to run the weight bars, our battery bracket system from the Late Model/EDM/Omni kits will fit in a transverse position in front of the waterfall (not included).
Lowers the center of gravity and gets the car lower than the stock aluminum chassis
Added additional servo hole 7mm forward of stock to allow installation of aftermarket servo with straight horn
Ability to run a larger 1/12 servo using our 1/12 servo mount from the late model conversion
Eliminates the front mount of the sprint cage kit that bolts to the steering bellcrank posts - instead we use doubled up carbon and stainless steel standoffs to mount the cage in the same hinge holes on the cage.
Wider and more open chassis plate allows for more room to mount electronics or chassis weights

This chassis conversion kit will convert your Losi Mini-B into a full fledged oval sprint car. It also provides a left offset weight bias for better handling.

What's included in the kit:
Lower Carbon fiber Chassis Plate
2x Chassis Brace spacers
Kickup wedge (aluminum)
Aluminum Chassis spacer
Carbon Fiber front bumper
Carbon Fiber battery hold down
Carbon Fiber Nose reinforcement plate
Aluminum standoffs for battery hold down
Stainless steel front cage mount standoffs
3D chassis rails
Transmission shim
All necessary hardware

Note: This is a chassis conversion kit only. You will need to supply a donor vehicle as well as the Sprint car cage and body to make a complete vehicle.

If you have any questions, PLEASE DO NOT HESITATE TO ASK.
