you are on the right track, but just try silvers and skip green. If your car gets loose as the run goes at about 6min mark go to green. Crc also makes side springs that are in between that work nicely too.

You can also dope more of the front tire like all of it. When I run Blk ft (with green rears) I dope it all. Try 15k in the side dampeners too. One good way to check and see if you need thicker or thinner dampening is to disconnect one tube and go and run. If the car is better go to a lighter lube.
