You can use harnesses as long as they're securely (and properly) mounted and you don't remove the stock belts. However, understand that in a rollover situation, shoulder harnesses prevent your torso and head from being able to move to the side, so your risk of spinal injury is actually higher unless you have rollover protection. Not as high a risk of a roof-caving rollover in autocross as there is in race track events but figured I'd throw that out there for futures.
