I've raced a bunch of different cars over the last 30 yrs by myself now after pizzing the better half off She use to tow me around like we where big time racers I did win a bunch of Pro bracket races at LACR back in the day, before everyone else got better. I made the mistake once to often of hollering at her to hurry up when she was towing me near the 1/4 or semi final rounds, that was her last trip to the races with me a regular helper I run mostly bracket 1 and 2 cars now, not hard to make a car run consistently without breaking it N/A if your careful I do run a alternator and volt meter to make sure it is working, I charge both RV/Marine batterys at 3 amps for two or three dyas before racing and again during the lunch and drivers meeting breaks at the local track IHTH
