I have yet to break a ride height adapter and have had side impacts hard enough to blow out the bearing. I've been using the IRS ones now for at least 4 of my last 1/12th cars and my WGT cars.

I saw the Team Tamale pod at the IIC and was pretty impressed with it. Unfortunately they don't make it for my BMI car But BMI has their own new pod in the works that uses spacers similar to the TOP car.
