NEW! BattCave JOK3R MAD Mini Front Bumper JKR-BP02

Specifically designed for the Phat Bodies M.A.D Mini bodyshell, our latest 3D printed TPU low-profile front bumper offers increased support and front impact protection by occupying most of the space under the MAD’s expansive front spoiler. Without it, a front-end collision could potentially force the front spoiler under the chassis, resulting in additional damage and loss of control.

🦇Made for Phat bodies MAD Mini

🦇Designed and printed in the BattCave. 

🦇Increases front impact protection.

🦇Low and wide profile offers additional support. 

🦇 M.A.D. specific rear bumper also available!

Core RC brass weight measuring 92 x 47mm and with 1mm thickness to allow you to position weight directly under your 1S or 2S shorty battery for the lowest centre of gravity. Super flat with Core RC logo etched on.

Introducing our new JOK3R silicone side bands!

Custom-moulded in silicone for better consistency.
Colour-coded for easy identification.
Wider tuning options.
Available in 3 different sets:

• Aqua – Neutral response set
• Lime – Medium response set
• Pink – High response set

Each set contains a total of 6 bands: 2 thick + 4 thin bands.

Also introducing the new BattCave Side Band Organiser Box - designed by Aiden Monk!

Designed by Aiden Monk and proudly featuring the BattCave logo, this sleek side band storage solution lets you easily transplant your existing side band holders into a smart, well-fitted box. Perfect for those who likes a tidy pit table.

*Picture of the box with inserts and bands installed (NOT INCLUDED!)

Recommended Usage:

•  Choose thick or thin bands (or a combination) to set your desired lean control (Thin allows more lean, Thick allows less lean).For example, you may want to use thin bands to allow more lean when grip is low, and thick bands when grip is high.
• Choose the colour to set your car's steering response. For example, you may want to increase your car's steering responsiveness on technical tracks, and reduce it on wider, flowing tracks. 

Care:
To keep the bands in tip-top condition, when not in use we recommend storing them in their case and avoid contact with solvents or brake cleaners.

We’ve made small design optimizations to the BattCave JOK3R Mini A-Arms with the new V2 design!

• +0.5mm Ride Height Adjustment: This change provides additional front clearance, perfect for those running ultra-small front tires.

• New Stronger Material: Improved impact dissipation and overall parts durability while maintaining the quality and performance you expect from BattCave.

• All New Steering Buffer Limiters: For a limited time, every V2 design set includes our all-new steering buffer limiters—designed to better dissipate impacts and enhance durability of the front end in hard impacts.

Currently, we are offering the 2+0, 2+1, 4+1 and 7+1 geometry options, with our other geometries rolling out over the next few weeks.

Important: We do not recommend mixing V2 arms with the original release spec. Due to the +0.5mm ride height adjustment, mixing will result in uneven ride height on the front end from side to side.
