Just finished a 2" Yana shiki drop. First of all they don't use the bushings so it's grease em and in they go. I did it without removing the engine cover. I will admit it's was near impossible without the impact bit it can be done as you've read... But tough.
The look is fantastic, read the tips, use the tips on here.....and don't install them backwards like I did I.... Lol, yes I got the joy of installing them twice. It's much easier the second time, not more fun, but easier.
