The Roval is Just a Really Fast Road Course

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.

How to Make Grippier Racetracks Using Spy Technology

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 substance affects the track before continuing to use it. A couple of drivers expressed similar…

The Secrets of PJ1 TrackBite

That sounds like the title for a Young Adult book, doesn’t it? What the Heck IS PJ1 TrackBite? NASCAR announced that they are again going to treat the corners of the track at New Hampshire International Speedway with a magic liquid called PJ1 Track Bite. The track enhancer has been…

How Tracks Take and Lose Rubber

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 a different racetrack. To get the details of how a racetrack changes from “rubbered up”…

Tire Management

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?

The Kansas Monozone Tire

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 get the best of both worlds by combining a harder compound on the inner 2-3…

Whose Fault Is It? Tires or Track?

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.” said race winner Kevin Harvick. Normally when you have a lot of cautions, the drivers’…

Can We Race Stockcars in the Rain?

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.
