The bumpers are both tbone racing as I found they offered a great blend of style and function. I've looked at lots of models and the only one that came close is the revo 2.0 but that will need replacement servos, replacement tie rods and sooner rather than later replacement wheels and tyres and so worked out even more expensive than the tekno. I've taken my time with the build and everything has been done to the very best of my ability
