Just wanted to check in and let you know that the packs are still running great! Went to a big trophy race in West Virigina back over Memorial Day weekend. It was my first time at the track, first time ever on asphalt with foam tires, only had 3 minutes of practice, and still won by nearly a lap.
The following week I ran my new car for the first time on carpet, and won by nearly 2 laps! My IB batteries aren't falling off at all during the full 5 minutes. I'm turining some of my best lap times at the end of the race! They run just as fast as your 3300 zebra packs too! Can't go wrong either way.
