None of us have run the car on asphalt. You can probebly get it to hook up due to the slammed tbar even though the car is generally too stiff for asphalt. Try 0.063 tbar, 0.018 front springs, 5 degree front blocks (might mellow out the car on turn in, I assume you're having trouble getting the rear to stick). Lightest rear spring (olive/green I think) with 30wt oil. Light/med damping fluid. You can also try jacking the front of the tbar up 1mm with shims. This is a mod trick to get more rear traction. Ask the locals about tire combinations...
