they are better at higher speeds through bumps and better at controling body roll and will not bottom out on jumps and g-outs also great at taking the kick out the rear at high speeds.but the stock rezzi's have alittle softer valving in them at slow speed rock crawling. i guess its what your going to do with them. i'm not using these to there full potential.hope this helps. todd at hunterworks uses them for gncc racing with great success.
