"This is the most honest 100TW tire on the market. If you’ve got a high horsepower car and the goal is to win, I’d almost always run these. It’s about maximizing the car’s capability without over-spinning the tire.”- Chelsea DeNofa

CHELSEA'S PRO TIPS
when to run the 651 sport xtra
The 651 Sport XTRA is built for high-power drift cars and heavier chassis setups where control under load matters most. It’s the go-to choice when you need maximum forward grip, stability, and confidence at higher speeds. You're not throwing money at a tire that doesn't work, the XTRA is the best tire to maximize cost per lap in competition.
It’s also a favorite front tire for drivers who want sharper steering response and predictable turn in during aggressive driving.
HOW THE XTRA HANDLES BIG POWER
A lot of tires claim they can handle 200-300tw performance, but rely on soft compounds that wear quickly when pushed hard.
The 651 Sport XTRA uses a true race compound (100TW) designed to handle sustained power without excessive wheelspin.
Instead of forcing you to overdrive the tire, it locks in grip, allowing smoother transitions, better control, and more consistent drift lines.
WHY THE XTRA STAYS CONSISTENT
The 651 Sport XTRA is built for long runs and high heat. Once it reaches operating temperature, it stays predictable and stable even during aggressive driving.
That consistency makes it a strong choice for competition runs, high-speed tracks, and hot-lapping sessions where maintaining grip under sustained heat is critical.

Chelsea's Setup Tips:
- Alignment: Maintain 3/8" to 1/2" total rear toe-in. No need for more unless the car lacks other tuning tools.
- Camber: Adjust based on track layout and grip levels.
- Tire Pressure: 20-30 PSI is the balanced spot. Drop to 12-15 PSI for maximum forward traction. Can be run up to 60 PSI without issue.
Bonus Tip: These warm up quickly. Manage them by lap length or wheel speed to prevent them from leveling off at extreme temperatures.
