Not just slow the steering down, but FIRST place a LOT of CASTER in both sides equally, so the wheels will naturally point straight down the track.
If the car was set up for circle track you would be amazed at the Ackerman, Bump Steer and geometry difference you will find betwen each side. You might even have to relocate one or both upper a-arm mounts back to achieve at least a 3 to 6 degree CASTER in both sides.
