Widens the wheel base.
It took a while for me to figure out how to put it together, I needed to use the original outer wheel hub/ retainer before screwing in the shaft. Looks awesome and stabilized the car around corners. Waiting for a gyro....

Better than others I tried.
A little hard to install. No other issues.

Unreliable
Two of the four axle extenders were mis-drilled, the holes weren't made straight through the extender, so the retainer pins wouldn't seat correctly. After re-drilling, was able to get them installed but the remaining metal is pretty thin and I don't know how well they'll hold up to the stress of driving the car.

Good extension part
Perfect for hub extensions

Some modifications needed
Get some blue locktight for the screws or lock washers. The pin holes for the axle are some what off so I had to file away some plastic on the wheel bearing housing otherwise the wheel wouldn't rotate. Other than that they work great!

Use these if you want to smoke your motor.
Only 3 out of 4 fit, and the fit was so poor that my motor almost burned out. The holes were not drilled on the same plane as the bearing face, which is a problem since that is a constraint for it to function. That, and this uses standard machine screws. The concept is excellent, but the tolerances were too loose on critical dimensions.

Cool
Work great! Bang for your buck.

Lasted 5 minutes
The material is so soft that even a modest 3S car stripped the screws out of the extensions and resulted in the loss of parts.

Snug fit , but works!
Does what it's supposed to do , snug fit while putting pins in. First time out the screw that goes through the wheel and into the extension unthreaded itself resulting in my wheel falling off. ( lost the screw ) Also found the screw holding another tire was loose. I will go to my local RC shop to get a new screw. These extenders should have came with lock washers instead of falt washers to avoid this issue
