what kind of crystalyte controller do you use ?

40 amps ?

[therhubarb]

can't remember what was in this version. Currently using 35A crystallite with 12 4110 fets. Want to get round to posting newer vids, even faster! Now using 3 x 24V 10AH Ping Batteries, very reliable. ~US$200 each.

At what speed does the kmx kart start to feel unstable? And what size wheels are you running?

[therhubarb]

gets a little hairy around 60kmh...  16" at the front and 20" at the back. Bigger wheels (like on the new KMX's) would be more stable.

[therhubarb]

I've switched to using softer tyres and lower pressure. Slightly lower top speed, but much more stable and slidable.

does it still have the rear disc brake. I have the 24 speed xclass and want to put a motor on it.

[therhubarb]

You can keep the rear disk depending on which motor you use. Crystallite motors don't leave enough room, the Puma motors do have space.

I recommend replacing the front disks with good quality hydraulic disks for controlled braking from high speed!
