What's good spring rate for tokico illuminas/gc coilover sleeves???

So Im about to purchase tokico illuminas with ground control coilovers but dont know what spring rates to run with this set up? This is going to be a DD and will see the drag strip once in a while if u have any suggestions please reply!!!

and since i dont want to start a thread about this question i’m going to pose…i want to know if DA/DB1/DB2 suspensions are interchangeable…havent gotten much success in my thread

Yes they are all interchangeable.
