yeah they both need a change of gravity. the truck is insanely easy to lower, all you need is rear blocks and torsion bars up front basically adjust the way you want it. the b210 takes a bit more, blocks can be used in the rear and either cut 240z coils up front or there is a set of adjustables out there but they are expensive and need welding to install. don't really know why but that is what the site says. funny how they are both orange, it wasn;t planned at all. i thik orange is a great color for older cars. it fades nicely
