I am preparing a 89 CRX B16 (cage going in next week), and will be using tokiko illuminas, with 400/600 f/r ground controls to start out with. I have talked to guys with similar setups and the consensus is that it would be a good starting point while I am still learning.
I have seen some pretty high spring rates, like 1000/1200 being used on some cars, but would require a shock that is valved to handle it. I think Tyson has a nice FAQ on this at Honda-Tech.
