1. One of the most over looked pieces when converting a flat kart to a cage kart is the way the cage connects to the flat kart. 

• Receivers need to be able to move on the flat kart frame freely, or the cage will not allow the flat kart to transfer weight properly.
• The Cage Should float Freely on the springs inside the receivers. If you have to force it to move then the cage needs slightly adjusted for better fit. You should be able to use 1 finger to move the cage up and down on all 4 corners
• Spring length is paramount, do not cut the springs to be shorter than supplied by the manufacturer, this will cause the kart to hop when exiting the corner.

2. Time and time again we see cage karts running flat kart nerf bars /side bumpers that just aren't safe.

Cage karts are heavier than flat karts and require more external safety protection for the driver. Standard flat kart nerf bars are not enough to keep another kart from entering the cock-pit. We've seen multiple flat kart nerf bars fail during on track incidents involving multiple karts. High impact nerf bars that have multi-dimensional bends are much safer and can fend off the hardest of collisions. These nerf bars are virtually uncollapsable.

3. Tabs for mounting your hood and body panels are must. 

Not only do pre-welded tabs make installation easier, they're also an often overlooked safety device. If you install a cage, try to find one that has these tabs or have them welded on ahead of time. This will allow you to remove your hood and body panels quickly and easily if something occurs on the track. We often see bolts and zip ties used to hold on these body parts, these are not easily removable and make it extremely difficult to work on parts that may be covered by those panels.

4. Interchangable Wing and Parts

It seems inevitable that at some point most karts have at least one panel or another scratched, folded, squished or just plain destroyed. Finding a wing that is mass produced is your best option for being able to replace individual parts rather than the entire wing. If you're looking to save money and time one of the most efficient ways to do that is by replacing individual pieces on your kart rather than an entire section.

5. Front Bumpers specially built for cage karts and cage kart hoods.

Due to the hood mounting differently to the cage kart the standard flat kart bumper doesn't perform very well when it comes to protecting the hood and acting as a true bumper. When building your cage kit make sure you account for a new bumper in your build, to protect your hood from typical race situations. There are two standard cage kart bumpers one that the hood sits down in and one that the hood sits on top of either is fine. Each has it's advantages but both work to do the same job.
