i installed the hpp germany 17mm wheel hubs an wanted to let everyone know they work perfectly to eliminate wheel wobble from the stock adapter setup. worth every penny, only thing is they don't fit my cyclone rims which use a special smaller adapter. hpp offered to return them but they work too well, I'm running the stock rims for now. thanks to scaniris for his vids an recommendations. i also installed mips axles with red lock tight an one aluminum diff so far. had gh axle carriers but they were the wrong part, revo an summit carriers use different bearings, so I'm waiting for those next week!
