Mabuchi - Sorry for the wait, I'm still working on it. Things have been really, really busy.
Tabushi - The Reds (A-7760R) are among my favorite tires for 1/8th scale, especially when the track is made of soft dirt, or the track is cold and slimy (like when it is watered at night). When the track is hard packed, they may be a little tall to carry lots of corner speed, but I've used them to practice on all sorts of track conditions.
