Late Model & Sprint Car national tour results from the past week, plus what’s on deck next week.
Nine laps to go at Lawrenceburg Speedway last night, Tanner Thorson slides off the bottom lane, tags Aaron Reutzel square in the right rear, and Reutzel goes upside down on the 3/8-mile Indiana clay — red flag, car on…
Listen + transcript →Lap 87 at Wheatland, Missouri. Bobby Pierce, who started fourteenth in a field of thirty on a three-eighths-mile surface that had gone completely slick and shiny by intermission, threads the needle past Jonathan…
Listen + transcript →Thirty laps, pole to checkers, zero surrendered. Aaron Reutzel crossed the stripe at Texas Motor Speedway with Corey Day 0.720 seconds back, and the 87 car never gave the field even a breath of daylight to work with.…
Listen + transcript →Audio deep-dive on each published column — setup science, physics, and the numbers.
You walk back to the trailer after the feature and you say the track changed on you. No. The track did not change on you. You never knew what the track was. Eldora Speedway sits on a Celina silt loam — an Aquoll — and…
Listen + transcript →A 10.52 on a 10.50 dial. Reaction time 0.027. Sixty-foot 1.582. That time slip is not a trophy — it is a setup sheet, and if you are only reading the ET and the win light, you are leaving rounds on the table. This is…
Listen + transcript →Picture this: it's August at Limaland Motorsports Park, the surface has been polished glass-slick, and you reach for your second compound bin — the F85A Hard right rear you've trusted for a decade — and it isn't there.…
Listen + transcript →Imagine you just durometered a D30A and an A40 back to back. Cold, same temperature, same spot on the tire. They punch within five points of each other. You think you're looking at a simple soft-to-hard progression. You…
Listen + transcript →Picture this: Saturday night, wet dark clay, rooster tails off every kart in the feature — and the guy next to you just pushed his rear hubs out to forty-five and a half inches on a track that's already doing all the…
Listen + transcript →Picture a parent crew chief standing under a light bar at 9 PM, 5mm Allen wrench in hand, staring at two small aluminum slugs pressed into a spindle. Those slugs are the entire suspension system on a solid-axle dirt…
Listen + transcript →Picture a parent standing at a tire trailer at a one-sixth-mile bullring somewhere in Oklahoma or Texas, holding a tire catalog, staring at it like it owes them money. One of their kids runs a kart. The other runs a…
Listen + transcript →Picture a fresh-cut SS-33A punching 52 on a Shore A durometer at seventy degrees ambient — and then picture that same tire on a calcium clay bullring in southern Indiana that's gone from soupy to glass in fourteen laps.…
Listen + transcript →Picture this: it's lap eight of a Jr2 feature, your kid qualified third, looked fast in the heat, and now the kart is sliding around like it's riding on a wet sponge. You pull the right side off post-race and stick a…
Listen + transcript →Picture this: it's 5 PM, your durometer reads 38, and the track went from river-bottom slimy to bone-dry hardpan between hot laps and the heat race. You've got a set of Vega Yellow and a set of Maxxis ST3 White sitting…
Listen + transcript →Picture a right rear kart tire that reads thirty-two Shore A on the durometer at hot laps — soft as chewing gum, sticking to red clay like it owes money. By lap six of the feature, that same tire reads thirty-nine and…
Listen + transcript →Picture this: a 410 sprint car on a glass-slick 3/8-mile late in a feature, driver rolls into the throttle off turn two, and the rear end just rotates — not because of tire grip, because the geometry is doing it. Two…
