Finally got to do an autocross after I put my Rally 3 Schroth harness in. I installed it with my existing seat belt still in place for regular driving duty. I don't think you would want to use this on the street. I had to pull my seat out to get the lower right bolt loose on the seatbelt mount. Other than that, no big deal installing, just read directions.
On the track, I don't think there were any monumental advantages but I did find myself concentrating more on driving than holding on in some areas. So it does work to hold one in place. Especially when trying to grab sunglasses on the dash after already helmeted and strapped in (duh). Only negative I could find was that the shifter seemed a lot further away because of less shoulder rotation and thus reduced reach. Adjusted seat one click fwd helped but now I have to re-learn new driving position. Rich Blake
