I would either go with a set of Yellows or ditch those springs.
I had a set of adjustable Tokicos on my 07 (no yellows available for that year) and it was OK when the shocks were stiffened up. Not great but OK. The sportlines are too soft until theyre compressed a lot and by then you're already on the bumpstops.
