We want to take a moment to give a HUGE thank you to Insane Performance for their unwavering dedication and support of Penwell Knights Raceway!

From keeping our racers going with top-quality parts, service, Sunoco fuels, and nitrous… to going above and beyond by donating their wrecker to support our Safety Team at the track — their commitment does not go unnoticed.

Year after year, Insane Performance continues to show what it truly means to stand behind a racing community. Their loyalty, hard work, and passion have played a big role in helping our racers perform at their best and ensuring our events run smoothly and safely.

We are proud to have them as part of our Race Family, and we truly appreciate everything they do for Penwell Knights Raceway.

Thank you for the years of continuous commitment — we couldn’t do it without you! 💪🏁
