Caliber M3 compound worked great on my Losi 2.0 on my local Florida clay tracks. When the track is dry the deep pins offer incredable traction in the turns and axcelerating. When used on the damp clay the step pin does not clog and rockets you to the front of the pack! Worn Calibers rip the blue gruve track so you get max life from this tire.

These tires are the next level! I tried them compared to holeshots and the car felt more planted and still did faster laptimes.
