Multiple Cup Teams Fail Pre-Race Tech
NASCAR inspectors flagged issues with two competitive cars during the initial tech inspection Saturday, May 10.
The No. 34 Front Row Motorsports Ford of Todd Gilliland and the No. 45 23XI Racing Toyota of Tyler Reddick both failed twice through the inspection line.
Per NASCAR rules, both teams lost their car chiefs for the remainder of the weekend and forfeited pit stall selection privileges for Sunday’s race, NASCAR.com reported. Joe Marra (Gilliland’s car chief) and Michael Hobson (Reddick’s car chief) were sent packing while both teams fixed the issues ahead of their third inspection attempt.
Front Row competition director Chris Lawson spoke to reporters about the impact Saturday afternoon.
“Not having Joe here hurts us,” Lawson said. “We’ve adjusted who handles what duties, but it’s not ideal. At Kansas, every adjustment matters.”
Reddick, who qualified fourth, took the bigger hit by losing his preferred pit location.
“Tyler’s guys are handling it,” 23XI boss Denny Hamlin told Fox Sports Sunday morning. “But starting fourth with a bad pit stall isn’t what we planned.”
Inspection Issues: What Got Flagged
NASCAR didn’t specify the exact violations for either team, standard practice for at-track inspection failures.
NASCAR tech inspector Mark Stevens explained typical Kansas issues in a Tuesday interview.
“Teams push boundaries at intermediate tracks,” Stevens told Motorsport.com on May 13. “We typically catch rear quarter panel specs, underside aero tricks, or rear window assembly mods.”
Team sources suggested 23XI’s Toyota had rear skew measurement problems while Front Row’s Ford showed front splitter height issues. Neither team confirmed these specifics when asked.
Cup teams constantly fine-tune their cars to the edge of NASCAR’s strict tolerances, often working in thousandths of an inch margins.
NASCAR’s Tech Penalty Structure
NASCAR uses a clear penalty system for inspection failures:
- First fail: Fix it, no penalty
- Second fail: Lose car chief + pit selection (happened to No. 34 and No. 45)
- Third fail: No qualifying + pass-through penalty at start
- Fourth fail: 10-point penalty for driver and owner
For more significant tech violations, NASCAR applies its L-level system:
- L1 Penalties: 20-75 points, $19,000-$76,000 fines
- L2 Penalties: 75-120 points, $76,000-$190,000 fines
- L3 Penalties: 120-180 points, $190,000-$380,000 fines
When NASCAR spots potential issues needing detailed analysis, cars head to the R&D Center in Concord for teardown inspection.
Race Day: Penalties Pile Up
Officials kept the flags flying during Sunday’s AdventHealth 400 with a season-high 26 penalties.
The most common infractions included:
- 15 drivers busted for pitting before pit road opened
- 3 drivers tagged for speeding
- Equipment violations for Bubba Wallace and Carson Hocevar
- Tire control issues for Austin Cindric and Justin Haley
These penalties reshuffled the field throughout the 400-mile race.
Wallace never recovered after officials caught a 23XI crew member interfering with pit equipment on lap 35. The resulting pass-through buried Wallace in traffic before his eventual DNF.
Cindric showed how to overcome penalties, rebounding from an uncontrolled tire call on lap 121 to finish 11th. Crew chief Jeremy Bullins made a late-race strategy call that gained crucial track position.
Multiple teams got caught during early cautions when pit road remained closed despite cars ducking in, creating confusion and a stack of penalties.
Post-Race: R&D Center and Truck DQ
NASCAR’s tech inspection continued after Sunday’s race ended.
Officials selected Chris Buescher’s No. 17 RFK Racing Ford and Carson Hocevar’s No. 77 Spire Motorsports Chevrolet for R&D Center inspection in Concord, Jayski confirmed.
The most severe Kansas penalty hit Layne Riggs after Saturday’s Truck Series race.
NASCAR disqualified Riggs’ No. 34 Front Row Motorsports truck from its second-place finish after failing post-race inspection.
Officials cited Rule 14.4.9.A violations regarding the truck’s bed cover, Autoweek reported. “Bed cover material must be strong enough to prevent the cover from deflecting or sagging and must be sealed around the perimeter of all bed panels while the vehicle is in competition,” states the rule according to NASCAR.com.
The DQ relegated Riggs from second to 31st place. Front Row opted not to appeal the penalty.
Points Impact Hits Hard
The Kansas penalties created major championship implications.
Riggs suffered a massive 35-point swing in the Truck standings. Previously headed toward eighth place, the DQ knocked him to 14th overall, now sitting 28 points below the playoff cut with seven regular-season races left.
Reddick’s struggles after losing his car chief contributed to a 17th-place finish that dropped him from fifth to seventh in Cup points, now 43 markers behind leader Kyle Larson.
Gilliland and Front Row lost valuable owner points in their battle to remain above the charter threshold for next season.
One tough weekend at Kansas could have season-long repercussions for these teams.
Legal Battle Adds Context
The Kansas penalties came during an intense legal battle involving two of the penalized teams.
Front Row Motorsports and 23XI Racing continue fighting NASCAR in court over the charter system through an antitrust lawsuit.
Just one day before Kansas inspection began, a three-judge panel heard NASCAR’s appeal against an injunction that allowed these teams to compete as chartered entries this season.
The judges signaled they might overturn the injunction, potentially forcing these teams into “open” status, which would require:
- Weekly qualifying on speed
- No guaranteed race entry
- Significant financial penalties
The 23XI organization has faced performance questions this season despite Tyler Reddick’s success last year.
Jeff Gluck from The Athletic recently noted the team’s lack of 2025 victories, writing in GPFans: “23XI Racing appears to have fallen off from their 2024 pace.”
Some fans questioned the timing of tech penalties for both plaintiff teams so soon after the court hearing, though no evidence connects the legal case with NASCAR’s inspection process.
Racing competed for fans’ attention during a busy sports weekend that included other major events like Navarrete’s boxing match against Suarez that drew viewership from motorsports audiences.
Immediate Team Impact
Kansas inspection penalties created immediate problems for the affected teams:
- Technical void: Car chiefs coordinate crucial setup details and adjustments
- Pit road disadvantage: Poor stall position costs time every stop
- Resource diversion: Teams waste practice time fixing inspection issues
NASCAR’s inspection process aims to maintain competitive balance rather than target specific teams.
The rulebook establishes clear boundaries within which teams can innovate, protecting the integrity of competition.
Riggs’ complete disqualification demonstrates NASCAR’s willingness to enforce rules regardless of competitive impact.
Kansas Inspection Penalty FAQs
Why did NASCAR select Buescher and Hocevar for R&D inspection?
NASCAR regularly takes cars to the R&D Center when officials need additional scrutiny beyond what track equipment allows. They typically select winners, random entries, and cars showing potential rules innovations. Results from the No. 17 and No. 77 inspections weren’t available as of May 14.
What duties does a car chief handle during a race weekend?
Car chiefs serve as the technical bridge between crew chiefs and mechanics. They oversee car preparation, manage setup changes, and ensure consistency across practice, qualifying and race configurations. When Reddick lost Hobson for the weekend, the team scrambled to redistribute these critical responsibilities among other crew members.
How common are pre-race inspection failures in NASCAR?
Pre-race tech issues happen almost weekly in NASCAR. Earlier this season, five teams failed twice at Las Vegas in March, and three cars had multiple failures at Darlington two weeks before Kansas. Teams constantly push dimensions and setups to the limit, especially at intermediate tracks where small aero advantages translate to significant speed.
Why did Front Row accept Riggs’ disqualification without appeal?
Front Row didn’t contest Riggs’ DQ because the evidence was conclusive. Team sources indicated the truck bed cover issue was clear enough that appealing would waste time and resources. Teams typically only appeal when they believe they have technical evidence contradicting NASCAR’s findings or when procedural errors occurred.
How much disadvantage comes from a poor pit stall?
A bad pit stall costs teams every single stop. Reddick’s qualifying position should have earned him a premium spot with clear exit lanes. Instead, he got boxed between competitors, adding 1-2 seconds per stop. At Kansas, where green-flag pit cycles determine track position, this disadvantage directly impacted his 17th-place finish.
Looking Forward From Kansas
Kansas Speedway Cup inspection penalties represent just one chapter in the ongoing technical battle between NASCAR and its teams.
The R&D Center will likely announce results for Buescher and Hocevar before teams arrive at Charlotte on May 25, potentially adding more penalties.
Front Row and 23XI await the court’s charter decision, which could fundamentally alter their operational structure mid-season.
Teams will analyze whether these Kansas issues were isolated incidents or signs of deeper technical problems requiring redesign.
NASCAR’s top championship contenders now understand that 2025 success requires not just raw speed but perfectly compliant technical packages.
For fans tracking the season battles, these Kansas penalties prove that sometimes the most consequential moments happen before cars even hit the track.
