BC Coilovers-how is the ride quality?

My IS350 with BC coilovers at stock 10kg/8kg rides pretty soft and comfortable at medium dampening settings. It's definitely smoother riding than my buddy's IS350 with sport package suspension, but he was also on 19" wheels whereas I'm on 18's. I guess if you're looking for a smooth comfortable ride, BC's will do well. If you're looking for pure handling, the stock 10kg/8kg are way too soft. I'm about to add a front F-Sport sway bar to compliment the rear F-sport bar to tighten up the existing body roll still apparent at high speeds.
The ride is also softer than my '05 TL with the factory optional A-Spec suspension as well as my coworker's '08 328i Coupe with sport package suspension.
I wouldn't recommend F-Sport springs and stock shocks even if you only want to lower 1". I helped a friend install some on his IS250 AWD and the ride is bouncy because the stock shocks can not handle the stiffer progressive rates as the suspension compression increases over larger bumps. It almost feels like he is hitting the bump stops, but it's hard to say exactly.

It definitely is a nice feature. It's also the reason why people think Megan/BC/KSport/D2 are all the same.
Heres the catch about tucking tire, most people that ride very low don't do so with comfort.
If you ride slammed and want a comfy ride, it's not possible unless you want to rub 24/7. People with agressive wheel specs and a very low ride height get a higher spring rate. This is what causes to be "crappy" and you feel every pebble in the road.

Correct, the lower sleeve is the part to adjust for ride height and locks with the lower ring. The two upper rings are to adjust spring preload. Lower sleeve does not connect directly to the springs. This type of coilover, changing the ride height will not affect the amount of shock travel.

^^ Something I wished the great Tein would have gone with this design for the 2IS. Their Super Sport and CS line of coilovers do not include a full set of top hats and must use off your oem setup.

I know a few high end companies that don't supply top hats at all. They sell coilovers in excess of $3000, and they don't offer dual height adjustments either, but they perform beautifully 
Some of the Tein models have dual height adjustment like the Tein Flex, but I don't know if they have an application for the 2IS. Even if they did, I wouldn't consider Teins at all.
