B4 Steering issue

[westie]

Alright guys, seem to have a problem with the steering on my b4, while racing i seem to have more bite turning right than left. ive rebuilt the shocks and checked to see if all the suspensions free also all the bearings are fine. ive set the steering so it just hits the stops on the hub carriers both sides. what could this be? tweeked chassis? if thats possible

Thanks for any advice
