@murph914 , unfortunately KW doesn't have HAS system for the non M cars currently.
I would say do Dinan. The 300lbs extra weight to the back only apply when you open the top.
And it will looks like you have 2 teenager passenger in the rear.
The other option, as JNoSol mentioned, would be a coilover.
I removed my EDC to a coilover, trust me, you don't miss much.
The KW Variant 1 or Variant 2 would be sufficient enough for your needs.
I personally wouldn't do Variant 3 unless I really want to track the car and fine tune the suspension to my liking.
But when I decided to do that, I most likely will pull a trigger to a real track suspension, such as; ohlins or JRZ.
