Well thats the thing ... i really dont know much about shocks ...so i dont know how much i would actually use the adjustables... im going to do maybe 3 road courses this summer and hit the drag strip a couple times...im not going to be racing everyweekend so not sure what would be best for me. I have the FRP C springs waiting on shocks to install everything at same time.
I run the Tokico 5-way adjustable shocks and love them. Once you start playing with the adjustment you will use them more than you think expecially on autoX or roadcourse racing. They take about 1 min to adjust all 4
The Illuminas and the D spec are both very nice. The Tokico HP are basically stock tho. They will work fine, but are not anything all that great. If you want an adjustable, Id do the D spec, I've heard it is the nicest adjustable on the market. However the Illuminas, seem to be more of a drag shock compared to the D spec. If you want a non adjustable, the bilstein are the best IMO. But if you are getting in to the really high end, the Koni Yellows are better than the Bilstein HD's. The Bilstein are better when re-valved by Maximum Motorsports.
