I am going to bring my firestorm back to life over the next week or so. I need to get a mamba max and a set of rear tires for it. The stock tires don't last worth a crap so i am looking for a harder compound to use. This thing only runs on the pavement. I prefer something i can get pre-mounted on HPI rims if possible. The hex's have that little lip on the edge so i would like to stay with hpi rims.
