NASCAR’s continued struggle to balance cost, safety and competitiveness led to using PJ1 Track Bite in 2017 at Bristol Motor Speedway. Since then it’s been used (mostly successfully) at other tracks. So what is it […]
This weekend marks the very first time NASCAR has run a race on the Charlotte Roval: a combination of the oval track we run in May with select portions of the road course in the infield. It’s a unique situation because, unlike most road courses, this one is contained. Fans will be able to see the entire course. Everyone is looking forward to seeing something new on this one-of-a-kind hybrid track. […]
If PJ1 TrackBite isn’t the Solution, What is? Dale Earnhardt, Jr. suggested tracks stop using PJ1 Trackbite because it didn’t work well in Charlotte last weekend. He called for additional research to understand how the […]
The two words we heard most frequently last week in Pocono (after “still raining”) were “green racetrack”. Rain doesn’t just delay racing. When the race is finally run after a rain delay, it’s run on […]
NASCAR is very clear about what teams can and can not do to the tires. Teams may not use any chemical or physical means of altering the tires, which means no siping (cutting grooves into the tires), no chemical softening, not even heat blankets to pre-warm the tires are allowed. Basically, you can’t do anything to the tires. This means that when a tire blows out, it’s the tire’s fault. Right? […]
Running on underinflated tires can be dangerous. Underinflated tires they create more friction and more heat, which leads to not only bad handling, but also can produce structural problems. […]
Equilibrium. It’s more than just a neat word. It’s the holy grail for a racecar driver. […]
OK, so ‘monozone’ is just a fancy way of saying it’s the old tire. It’s all in the branding, isn’t it? Goodyear has been experimenting with multi-zone tires since last year. Multizone tires attempt to […]
There were 15 cautions last week at Kansas Speedway and at least 15 drivers complaining that driving on the repaved track surface was like driving on ‘razor blades’. “The worst racetrack I’ve ever driven on.” […]
In sports car racing, the only discernible change the viewer sees when it rains is that the normal “slicks” (which have no treads) are changed out for rain tires. Thus the calls for NASCAR to develop a rain tire good enough to allow us to continue races, even when it rains. […]
