I have tracked it 4 times in the last 9 months and plan to do a day a month over the summer/fall. For my level on the track (probably intermediate?) and to maintain street comfort (my wife enjoys driving it too and she probably wouldnt want it any stiffer - the car guys, the car!) I was staying away from coilovers. If you had asked me before I knew about the issue I would have said that I wouldn't change the suspension (maybe that's my answer right there

).
Tire wear on the rear passenger and front drivers side were very uneven and pointed me to get the alignment done.
It looks like the OEM part is somewhat difficult to come by (special order from pelicanparts). Assuming that replacing 1 rear OEM with a Bilstein HD would be bad, is it ok to replace both rears with Bilstein HDs but not the fronts?
Thanks for the help.
