Hello There Fatbear,
Though I have not raced asphalt 1/12th scale in years I race carpet in the winter months you could try a Harder front spring or a harder front tire compound.
You may push alitte but it may be alittle easier to drive you can also reduce your caster block to a 5 degree one It will take away steering but It will be alittle more easier to drive.
Again my knowlege of running asphalt is limited I hope this this may help Theres a guy on here His name is Adrian he is sponsord buy Shumacher he is very knowledgable about running 1/12th asphalt as well as The guy from BMI to I think his name is Jason.
Hope this helps
Mike
