I started karting about 9 months ago, and I’ve wasted so much money on things that were absolutely not worth it. Just wanted to start a thread so others can save their money. Please add to this with anything you’ve bought and would not recommend!
Mychron 6
I bought this for the built-in steering angle sensor. Turns out, it doesn’t really work (not super surprised tbh). They’re supposed to have a fix, but I haven’t been able to test it yet. It also doesn’t support splits, which I loved to use on the 5. The 5 is amazing, love it and would highly recommend it, but the 6 to me, isn’t worth it.
AIM Steering Angle Sensor
I don’t know why they sell this as it is. It’s impossible to mount. I’ve seen some mount kits, but they only come with the sensor and I refuse to buy the sensor again.
AIM Tire Temperature Sensors
I struggled with learning to set tire pressures, but I knew you want them to be around 180°F. I thought I could use these to set the pressures and reach optimal temperatures. The readings would go from 130-170 and back to 130 in one turn. Turns out the external tire temperature fluctuates so much the data isn’t really helpful, in my opinion. Maybe to some the data is usable?
Fast Adjusters for Seat
These sound great in theory. They’re an absolute PITA to mount a seat to. And it doesn’t solve the fact that when you slide the seat forward, you still have to drill holes in the side and move the struts. They only really help with 2 out of 6-8 holes. The ones they don’t help with are the difficult ones where you have to remove a radiator and engine to drill. They save maybe 2 minutes on a 30 minute job.
American Shops
Order from Europe. Learned this recently and I’d estimate that I save at least 50% on average. I’ve gotten adjustable seat struts for $12, sets of Vega Whites for $149, water hoses that are $59 here (cough AKR cough) are $12!!! Shipping is usually 2 days for $20 from Italy or Germany. I just laugh when I look at the prices shops here charge. Last time I ordered an OTK part from my local dealer, it took 2 weeks to arrive. I can get any OTK part in 2 days from Europe. There’s just no advantage to ordering even locally.
New Line Turbo Water Pump
These water pumps, with the special power saver pulleys (which they require), and axle pulley, cost around $450!!! I live in Las Vegas and thought I’d need all the cooling I can get in the summer, they are supposed to cool much better. I took mine apart to change the pulley and 2 of the screws came out with the threads! New Line offered to fix it if I shipped it back to them and paid shipping both ways. I just super glued it together. Blows my mind how they charge so much for something made of plastic. Looks like it would cost 50 cents to make the main shell.
The Lab Paddle Shifter Kit
These run around $2k. The app was unusable on Android. Paddles constantly moved around no matter how tight they were. Battery was difficult to mount and maintain (fell off and got stuck under my front wheel going around a turn once).
Cheap eBay Kart Suits
Ashamed to admit it, but I bought a “Tony Kart” suit on eBay for $100 to see if it was legit. It has some random Pakistani guy’s name on it, smells like poop, and is paper thin.
