I just got a JRXS this past week and I haven't raced touring car in a full 2 years and been out of racing all together for a good year and a half. I stuck a carpet setup on it posted from the boards and tossed it on the track, my second battery with the car was in a heat and I misssed the track record by .28 and fast lap record by .03 sec. By the A-Main I had broke the record by over 7 sec and still had a few mistakes in that run.
I'm pretty happy with my decision to go with the JRXS.
