depending on the type of astro BB whites can be good; I find they have less side bite so not quite as hairy in the corners!
upping the diff oil can sometimes help too (you don't say what you are running).
in very high grip, stiffening the car can actually make grip roll worse as the suspension doesn't roll and absorb some of the lateral movement when you are cornering.
what ride height are you running; the 410 can be run quite low in most conditions and this could also help.
