Why Zenith Exists
We built Zenith on a simple belief: some parts of endurance racing are worth investing in—fairness, consistency, and competition. Our rulebook and standards are written plainly, and we apply them the same way every weekend with consistent staff at each event so the intent becomes reality.
We back those promises with people who’ve done it at the highest level. Zenith Racing operates in partnership with USAC (United States Auto Club) to bring the infrastructure, experience, and professionalism that endurance racing deserves—seasoned stewards and race-control officials, a Clerk of the Course who keeps the plan coherent, pit-lane marshals who prevent problems before they start, technical inspectors who value both safety and parity, and licensing support that removes ambiguity from expectations. The result is not just a rulebook; it’s a working system you can trust.
Trust also needs data. AlKamel anchors our timing: live position via GPS, class gaps, Driver- ID, stint counters, pit-window clarity—the granular truth teams rely on. We extend that precision to the outside world with elevated live streaming: multi-camera coverage, commentary that understands endurance, and real-time overlays driven by Alkamel. Fans see what teams see—class battles, pit cycles, strategy swings—so the competition is not just visible, but legible.
Culture makes all of this hold. We race hard and we draw a bright line. We are strictly a Non-Contact series. Clean racing is fundamental to a fair and fun event. If there is contact, penalties will be swiftly and strictly applied. The same clarity applies to integrity: cheating—fuel tricks, declared-power games—puts you outside the event. We value ingenuity, not deception. These aren’t slogans; they’re the conditions that let everyone race harder with fewer doubts.
We also believe that when incidents happen, neutralize the field with a clear, predictable Code-35–style procedure calms the field without disrupting the race. It’s a promise that safety won’t turn into chaos and that strategy can be planned, not guessed.
Our technical philosophy mirrors that clarity. We class cars with simple, transparent targets:
ZP2- Prototype class with a maximum power to weight ratio of 9.0/1
ZR2- GT style class with a maximum power to weight ratio of 9.0/1
ZR3- GT style class with a maximum power to weight ratio of 10.5/1
Performance is anchored to the ratio, then shaped by two linked guardrails that keep it honest and interesting: fuel capacity scales with power (more power, more fuel; less power, less fuel), and declared power is tied to weight via a published formula and verified in tech. Build what you believe in—then prove it. Within that framework, we welcome engineering: aero, engines, setup. Gains don’t disappear into gray-area penalties; they show up as choices your crew can plan around and your rivals can race against.
The Zenith Calendar Philosophy
Great racing is also about where—and when—we race. We prioritize marquee circuits in their best weather windows so the competition is intense and the experience is enjoyable for everyone. That means places like COTA, Sonoma, Barber, VIR, Watkins Glen, and Road America—scheduled for pleasant climates and optimal track conditions. Cooler mornings help cars and drivers, afternoons avoid the worst heat, and evenings deliver the kind of racing and scenery you want your team to remember. A thoughtful calendar respects budgets and logistics, but it also respects the human side.
Put simply: endurance racing is the purest measurement of a team’s ability to prepare, execute, and endure. Zenith is designed to honor that measurement—with USAC alongside us on the ground, Alkamel anchoring the data, an elevated broadcast that shows the race the way teams actually live it, and a calendar that places you at world-class tracks in the right seasons. We invest in the parts that let excellence show through. If that’s the type of event you want to compete in, bring your team, bring your plan, and come see what you can do when the clock won’t stop.
