The GTWORX Bilsteins and Yellows would probably be your best bet - really an easy and very well-rounded solution that doesn't lower the car too much. If I recall correctly they do have the same warranty as any other set of brand new Bilstein struts/shocks. Understandably the wait for them isn't optimal (if only Bilstein could produce them faster pace
I don't know as much about the H&R Coilovers - if they indeed drop a minimum
of 1.2-.3" that really is pushing it... especially since I have read that the progressive rates on them is soft(er) for a coilover setup, and aimed more towards street driving. However if the min height really is that low and the springs are soft.... no bueno in my opinion. If they do have Bilstein made dampers in them that's a plus.
Edit: Got curious after writing that and did some Googling: Looks like the H&Rs sure do have Bilstein-produced internals (to H&R spec)
