H&R Coilover vs. Bilstein H&R race

[small_m]

Here is my dilema.
I have the option of swapping out my current setup for a set of H&R coilover kit.
My car has a full M3 swap (engine, trans, suspension and what not). Right now my setup is Bilstein Sport struts and stock m3 springs at the front and Blistein Sport shocks with H&R race springs on the back. I like this setup very much and have been to the track a few times and it has a very neutral setup.
I have never used the H&R coilover kit but the price seems to state that it should be a good setup. So whats the concensous from you guys?
Things I have thought that may not work with my front end.
1, 6cyl is heavier, do the coilover have the right spring for this??
2, I have the 95 m3 offset strut hats and offset control arm bushings. Would I keep this setup or have to change to the ti setup
3, The m3 sway bar mounts to the strut housing and not the control arm like the rest of the e36 cars.

Let me know...
