I personally think these are the best rims for use in 12th scale, based upon the flex characteristics of the rims due to the different mounting offset. You get forward bite from the softer inside of the rim, but the harder outside edge maintains corner speed. Combined with the new(er) rear compounds, these are pretty wicked!
