They are obvious to you and I. Perhaps not to the OP?
Even if it is a coilover setup, wouldn't the spring rate depend a bit on what dampers were utilized? Or is that vice-versa? Kind of have to talk about the two items together with GC coilovers.
In a Major Manufacturer Coilover Set (Tein, Progress, whatever....), I don't think you get to pick your dampers. Except in the case of custom coilovers from Advance Design, Hot Bits, etc...
To some degree, it may also depend on whether it is a stock B13 chassis, or the chassis has been heavily reinforced.
Might also consider road conditions in his area, as well as his age and/or chronic injury list.
I think we need a bit more information.
