Cyclone & PRo 4
I have had both PRO 4 and Cyclone. PRO 4 is much more durable. The Cyclone has several issues that still needs addressing. Their Ballstuds on the outer rear camber links snap like twigs, and then half the screw stays in the caster block, making it useless. Their stock dogbones are very, very weak. The lightest tap and they bend like noodles. Poor quality for a kit of this price and hype. Now they have come out with version 2 dogbones which are supposed to be stronger, but they are about $14 each, and are hop-ups, instead of standard. The PRO 4 never had such issues!! Its rock solid and parts are much cheaper and durable.
