just wondering on a hpi rs4 evo with stage d..... should i lock up the front and rear diffs?

only the rear diff and tighten the front for some great drifting

thanks for the help also what do you mean by "tighten up"

use nitro tubing on the little triangle thing which the gears slot onto in the diff.
about 2mm of nitro tube, makes drifting alot easier. ill be posting a tut hopefully after the weekend on how to do this.
