We run e-scale indoors on a high grip track in the winter as well. In fact, we run slicks because our traction is so high. Here are a few set-up tips you can try before having to throw money at springs and/or sway bars.

1. Lower ride height. When we go indoors on high grip, our ride heights tend to be 5-7mm lower than outdoors.

2. Reduce the droop front and rear. Again, high grip wants less droop to keep the car flatter on/off throttle.

3. In the absence of a having heavier springs handy, I will stand the rear shocks up more to make the rear a little stiffer and rotate more freely.

4. Add more anti-squat. On high grip tracks, you don't need the rear of the car to squat and make more traction. You're goal is to free the car up and allow it to rotate to avoid traction rolling.

5. We typically run heavier springs and sway bars. You have to experiment here, but for me I tend to run 1 - 2 sizes stiffer front and rear for both springs and sway bars.

Tires are a huge debate when we go indoors on high bite. Some people (like myself) want the tire with the most grip and then I'll use set-up on the car to tune out the extra grip I don't need. Other people will just go to a hard compound tire or different pin (if you're running pin) to generate a little less grip. If I were you and traction rolling, I'd be happy with the tires and start tuning the grip out of the car.

Lastly and probably most import is that my driving style changes quite a bit from outdoor to indoors. When I go indoors, I have to tell myself to slow down and be more precise. I try to drive smoother and tighter and resist the urge to grab a fist full of throttle to power through turns like I might do outdoors. Racing on high grip requires more control and finesse to be faster. For us when we go indoors there is no truer saying than slower is faster.
