Reasons to not lower below 1" are two.
First - to not fsck up suspension geometry, or if you do, fix it back (hence mentioned roll center adjustment kit), second - to reduce CV joint extra wear due too big angle and quicker failures (hence diff riser)
Rake is just one of suspension setting, that works with all rest. In this case, when coilover manufacturer that designed them recommends such, i'd probably would go with that if know nothing better or have data/experience of other setting working better for me.
Still, rake doesn't mean that you also need to overlower (both front & rear). Just that front is a bit lower then rear in this case. If manufacturer reccomended ranges included -1" front & -0.8" rear, i'd probably would go with that, unless you plan also buying/installing other mentioned parts to correct mentioned issues of lowering more.
