when it comes to suspension there is no such thing as best, its all personal preference and opinion. imo i wouldnt even lower on stock shocks

I can't vouch for Eibach, Road Magnets, etc. since I have the Tein s techs currently. I will say, they provide a very comfortable ride, are reasonably priced, great handling compared to stock, and definitely filled in the ridiculous gaps in the fenders well. Definitely recommended by me.
2006 IS250 AWD - Tein / Joe Z / Steering damper (current ride) ~ more goodies to come

1999 Mazda Protege ES (K&N, Eibach, Tokico, Alpine, Zapco amp) ~ Retired
+1 on H&Rs IMO the best springs besides tein. gives you a good drop to minimize wheel gap and not slammed bouncing around with road magnets. also consider just getting coilovers, im regretting it now lol.
I have Road Magnets on my 2010 IS250, the ride is pretty decent, but compared the Teins i had on my Acura TSX & TL i think they were more comfortable. But my Road Magnets provide a sick drop. Definately the lowest springs out there for the 2G IS.
