1,618 Cars Across 110 Races as Touring Series Double Non-Series Fields

The Dirt Late Model world ramped up significantly this week. 110 completed races across 30 states represented a 22% increase in race count over last week's 90, and total car participation jumped from 1,349 to 1,618. The average field size dipped slightly from 15.0 to 14.7 — the extra races came primarily from smaller weekly shows rather than big-field events.

The story of the week was the massive gap between series and non-series races. The 15 series-sanctioned events averaged 26.6 cars per show, while the 95 independent races averaged just 12.8. That's a 2:1 ratio that underlines the draw power of touring series even at the regional level. Fairbury Speedway's Illinois Speedweek show topped the charts at 47 cars — a track that averages 15.2 on a typical night. The Comp Cams Super Dirt Series drew 36 and 33 at Batesville Motor Speedway, and Spoon River Speedway pulled 39 for FloRacing Night in America.

Super Late Model fields averaged 18.9 cars across 27 races this week — down from 21.8 last week. That decline is entirely driven by the mix: last week had more national-tour events pulling 30+ car fields, while this week's schedule included more regional and weekly Super Late Model shows. The 604 Crate Late Model class continues to show strength at 16.0 average, up from 15.4 last week, anchored by I-75 Raceway's 41-car field for the Best Plumber 604 Racing Series.

Limited Late Models led in volume with 36 races — the most of any type this week. Super Late Models led in average field size at 18.9, though that was down nearly 3 cars per race from last week's 21.8. Every non-SLM type ticked upward week-over-week, even if only slightly. The YTD averages tell the broader story: Super Late Models are averaging 14.6 cars across 527 races on the season, 604 Crate is at 16.0 across 161 races, and 602 Crate sits at 13.4 across 150 races.

The top three fields were all series-sanctioned — Illinois Speedweek at Fairbury (47), the Best Plumber 604 Racing Series at I-75 Raceway (41), and FloRacing Night in America at Spoon River (39). The standout non-series field was BAPS Motor Speedway in Pennsylvania, which drew 27 Limited Late Models on its own. Crystal Motor Speedway in Michigan (24 cars) and I-96 Speedway (23) both drew well above their season averages — Crystal averages 10.0 on the year, so this week's 24 was a 140% increase.

Series races averaged 26.6 cars this week compared to 12.8 for non-series events — a 108% premium. Every single series-sanctioned event drew at least 16 cars, while 28 non-series races drew fewer than 10. The Comp Cams Super Dirt Series held its draw across both Batesville nights (36 and 33), and the Spring Nationals put 17.0 average across two Kentucky stops.

The Southeast led in volume with 45 races, though Alabama dragged the regional average down at just 5.8 cars per event across its 8 races. Illinois led the nation in average field size at 23.1, boosted by the two Illinois Speedweek shows. Mississippi's two Magnolia Motor Speedway events averaged a strong 23.5 — one of the healthiest 604/602 programs in the country. Oregon remains a concern with just 7.3 cars per race across four events.

Week-over-week, this was a growth week by volume: 110 races vs 90 (+22%), 1,618 total cars vs 1,349 (+20%). The average field held nearly flat at 14.7 vs 15.0. The schedule expansion came almost entirely from the weekly show tier — small-field races that fill out the calendar as tracks across the upper Midwest and Northeast open for the season.

Super Late Model average field size dipped from 21.8 to 18.9 — a 13% drop. But context matters: last week had a heavier concentration of national-tour and high-purse events. This week's SLM schedule included more $1,000–$2,000 weekly shows that naturally draw smaller fields. The YTD average for Super Late Models sits at 14.6 across 527 races — this week's 18.9 is actually well above the season baseline.

The 604 Crate class continues its steady trajectory. At 16.0 average this week (up from 15.4), it's the second-healthiest type behind Super Late Models and the highest YTD average at 16.0 across 161 races. The 41-car field at I-75 Raceway for the Best Plumber 604 Racing Series was the second-biggest field of the entire weekend — across all types. Tracks that invest in strong 604 programs are seeing consistent participation.

On the low end, 28 races drew fewer than 10 cars this weekend. Alabama had six of them. The smallest fields were at Madras Speedway (3 cars) and West Alabama Speedway (3 cars in each of two classes). Small fields aren't inherently alarming — they're often in rural areas where participation ebbs and flows with weather and local schedules — but a pattern of sub-10 fields at the same tracks over multiple weeks would be worth watching.

Several tracks posted car counts well above their season averages this week. Fairbury Speedway led the way — 47 cars against a 15.2 season average, a 210% increase driven by Illinois Speedweek. Spoon River Speedway more than doubled its 18.3 average with 39 cars. Crystal Motor Speedway in Michigan drew 24 against a 10.0 average. Moler Raceway Park tripled its 6.0 average with 18 cars. I-96 Speedway posted 23 against a 6.8 average — a 238% jump.

Only three tracks posted significantly below their season average: Independence Motor Speedway in Iowa drew just 11 cars against a 22.7 average (a 52% drop), Fiesta City Speedway in Minnesota drew 4 against a 12.8 average, and Super Bee Speedway in Louisiana came in at 8 against 11.6.
