After your tire game is on point, I would swap those RTR supplied understeering-easy driving shock springs for something more race worthy... Green V1 fronts and white V1 rears like the original B5. These old rear motor cars like to be driven point and shoot. Use it to your advantage where possible, like those tight 180 corners. Grab brake and let the back end rotate, then punch it. I'm not familiar with the included servo. If it's kinda slow, kinda weak... the steering is bound to feel lazy.
