ooh most definitely yes. They are good.
Vx Lsc shocks on tc may well be cheeper though. Fronts £40 odd each
? B4 where £220 odd a set for the car.
Cheaper maybe, but are they as good as B4s? If not I would rather get the bilsteins.
I guess its a question of taste ?
I suspect b4's give a firmer ride over mv6 shocks regardless of springs.
With irmscher springs on mine it's difficult give an exact comparison to the spec you mention, some broken surfaces can be harsh not helped by 18's, however the lack of roll, quality of damping, and feel and feedback is marked.
If your looking to firm up Elite but not compromise on comfort at all then mv6 lsc is fine.
From soft down to hard, that I have tried. ignoring stock spec for a mo ( cdx, cd, gls etc)
Elite shocks and springs. Soft wallowy, giving rounded tyre wear profile, handling degraded quickly, very comfy if driven steady.
Mv6 lsc springs with elite shocks include sl. Improved role less see sickness. Comfort still good
added front lsc shocks . Firmer ride but still supple but needed rears shocks as well. Still some sway at the back. Comfort still good but improvement not quit enough so didn't bother with mv6 lsc rear shocks and went straight on to...
New Irmscher springs with b4 all round. Marked Improvement in roll, bump steer, damping independence per corner partly due to binning sl shocks ESP at the back. Car tracks better in a straightline, holds aline better in corners, better corner speed and confidence. Far far better high speed stability.

Some harshness on poor surfaces approaching mildly "Crashy" ride on broken Tarmac but ok, good on good surfaces. Some "wumps" transmit to passengers a bit worse.
18's fitted, corner speed up 10mph from 60 to 70 possibly more to come. Poor suffices harsher still. Need to be more careful breaking on potholes etc. Slight loss of acceleration.
The firmest omega I have experienced is way softer than Audi A3 or BMW m sport ime. Crashy ride!
