hmmm, a whole 2wd outdoor season on a single 4600. tire roaster, only played between 2T dependin on track size, ran same mild temps all year. hot/cold/clouds/sun. i'd roast b4 it did. and of the spectacular blowups, they were all the original LRPs. and hard to beat that speedo (maybe phelps' speedo can, but not the other companies lol).
