iRacing Season 4 Week 2 is live from September 15 through September 21, and it is one of the fuller weeks of the season. NASCAR stock cars tackle Bristol Motor Speedway on the short oval circuit, the platform’s first-ever Britcar 24 Hours special event opens at Silverstone, and a new daily racing series called Track Day makes its debut with a 12-car multiclass lineup. Challenge events, new championships, and dirt programs fill out the rest of the calendar. Here is what is running this week.
NASCAR at Bristol Motor Speedway
The NASCAR iRacing Series rolls into Bristol Motor Speedway for Week 29 of 36. Gen 7 stock cars hit the high banks on the 0.533-mile concrete oval, which is one of the most demanding short oval environments on iRacing. Bristol rewards setup precision and patience as much as outright pace — the banking generates massive grip through the center of the corner, but the walls are never far away and racing is always close.
Expect tight fields, heavy contact in the turn entries, and a lot of attrition as the week goes on. Managing tire wear over a full run is the key differentiator between clean top-10 finishes and early exits. The Gen 7 package has been the backbone of the NASCAR iRacing Series since its introduction, and Bristol is one of the tracks that shows the car’s short oval capabilities best. If you have been running the series all season, this is a strong week to bank points.

The Britcar 24 Hours at Silverstone
Running as a special calendar event separate from the regular season schedule, the Britcar 24 Hours presented by Cosworth takes place at Silverstone this week. This is the first time iRacing has offered the Britcar endurance race on its special events calendar, and it is a meaningful addition for team endurance racers. The race uses a GT3 and GT4 multiclass format and runs from daylight into night, so managing headlights, traffic between classes, and driver fatigue across stints are all real variables.
This is a team event at its core. You will want co-drivers lined up, a pit strategy mapped to the class mix, and some time to practice race starts and mid-race stint transitions before you commit to a session. A dedicated Britcar 24 Hours event guide is on the way separately. For now, lock in your team and get familiar with the Silverstone layout at race pace.
iRacing Season 4 Week 2 Launches Track Day and More
Beyond the headline events, iRacing Season 4 Week 2 brings the debut of Track Day, iRacing’s new daily racing series. Sessions run at Summit Point with 12 eligible vehicles: the Porsche GT3 Cup Car, Mazda MX-5 Cup, TCR, and the Caterham 420R all feature in the multiclass format. Track Day is built as a lower-pressure on-ramp for drivers who want to try a variety of cars without committing to a full series schedule. It runs daily, so there are plenty of entry points throughout the week.
The rest of the weekly lineup covers road, oval, and dirt. Ring Meister by LVRY puts the Caterham 420R at the Nürburgring, which is exactly the pairing it sounds like. Rain Master Challenge by Podium1 runs GT3 cars at Summit Point in light rain — a test of car control that punishes overconfidence. Draft Master Challenge by SIMAGIC sends Gen 4 Grand National cars to Talladega for pack racing.
On the dirt side, 410 Sprint cars run at Lucas Oil Speedway and Dirt Super Late Models head to Knoxville Raceway. The NASCAR Modified Tour visits Concord Speedway this week. The FIA Cross Car Championship also makes its iRacing debut, running the rallycross layout at Winton Motorsport Park.
For the complete schedule and session times, see the official iRacing This Week post. Whether you are chasing series points at Bristol, putting together a Britcar team for Silverstone, or just want to try a few cars through Track Day, iRacing Season 4 Week 2 has racing across every discipline. Sessions are open now.
