Sorry, I didn't mean that they were junk, what I meant to convey is that these are not any kind of special bearings, they are standard-sized bearings, the same
size as the ones we already sell for Mini-Zs, but of lower performance. I meant to draw a contrast between our purpose-built XMOD bearings, which are a TRC exclusive, factory-made to our specs, and something that anyone can go to a hobby shop and purchase from loose, consumer-grade, standard-size bearings. As you point out, the kit is not usable w/ 4WD, which is precisely why we are developing a kit that is of the correct size. I certainly didn't mean to offend the seller or any buyers of the product, just looking to protect users who may misinterpret that auction as being some sort of XMOD-specific bearing set that won't require significant hacking in order to work.
