iRacing Sebring 12 Hour 2026 — Full BOP Breakdown and Endurotech Race Preview
Endurotech Racing fields seven cars across two classes at the iRacing Sebring 12 Hour 2026: five GT3 entries and two LMP2 entries. This is our biggest single-event deployment of the season. Here is our full race preview, the initial Balance of Performance breakdown, and how the team prepared across a structured testing week.
What Is the iRacing Sebring 12 Hour?
The iRacing Sebring 12 Hour is a flagship annual special event held at Sebring International Raceway in Florida. Built on a former World War II airfield, the circuit is famous for its rough concrete surface, brutal bump sequences, and the relentless physical demand it places on both car and driver across 12 hours of racing.
The event mirrors the real-world IMSA WeatherTech SportsCar Championship round with full multiclass racing across GTP, LMP2, and GT3. Unlike standard weekly iRacing races, the Sebring 12 Hour demands genuine team coordination: fuel strategy, timed pit windows, driver rotation, and incident management within a 50-point team limit. It rewards the prepared and punishes the improvised.
The iRacing Sebring 12 Hour runs Friday 27 to Sunday 29 March 2026 across four start windows. The prime slot for our Australian and New Zealand drivers is Friday 22:00 UTC / Saturday 8:00 AM AEST, with the race finishing Saturday evening local time.
Start Slot Guide — AEST and NZST
| Start (UTC) | AEST | NZST | Notes |
|---|---|---|---|
| Fri 22:00 | Sat 8:00 AM | Sat 10:00 AM | Prime AU/NZ slot. Finishes Sat evening local. |

| Sat 16:00 | Sun 2:00 AM | Sun 4:00 AM | Americas-friendly. Tough for southern hemisphere. |
Initial Balance of Performance — Sebring 12 Hour 2026
The initial BOP has been released across all three classes. Balance of Performance adjustments apply weight penalties, power reductions, and fuel capacity changes to maintain competitive parity across the field. Endurotech Racing entries are highlighted below.
GTP / Hypercar Class
| Car | Weight Penalty | Power Adjust | Fuel |
|---|---|---|---|
| Acura ARX-06 GTP | 0 kg | 0.00% | 99% |
| BMW M Hybrid V8 | 0 kg | -0.25% | 99% |
| Cadillac V-Series.R GTP | 0 kg | 0.00% | 100% |
| Ferrari 499P | 12 kg | -1.50% | 96% |
| Porsche 963 GTP | 7 kg | -0.25% | 100% |
The Ferrari 499P takes the heaviest hit in class: 12 kg of ballast and a 1.50% power reduction, indicating it was considered over-performing from previous events. The Acura and Cadillac carry no penalty and arrive at Sebring with a clean slate.
LMP2 Class
| Car | Weight Penalty | Power Adjust | Fuel |
|---|---|---|---|
| Dallara P217 EDR x2 | 0 kg | 0.00% | 100% |
With only one car in LMP2, the Dallara P217 runs completely clean: zero weight penalty, no power adjustment, and full 100% fuel capacity. Both Endurotech LMP2 entries go into Sebring on an unconstrained setup. In a single-car class, the race is decided by pit execution, driver consistency, and traffic management through the GT3 field.
GT3 Class
| Car | Weight Penalty | Power Adjust | Fuel |
|---|---|---|---|
| Acura NSX GT3 EVO 22 | 10 kg | -1.00% | 97% |
| Aston Martin Vantage GT3 EVO | 15 kg | -1.00% | 98% |
| BMW M4 GT3 | 5 kg | -1.00% | 98% |
| Chevrolet Corvette Z06 GT3.R | 5 kg | -0.75% | 97% |
| Ferrari 296 GT3 | 5 kg | 0.00% | 98% |
| Ford Mustang GT3 | 10 kg | -1.25% | 100% |
| Lamborghini Huracán GT3 EVO | 10 kg | -0.50% | 97% |
| McLaren 720S GT3 EVO | 5 kg | -0.50% | 98% |
| Mercedes-AMG GT3 2020 | 5 kg | -1.75% | 99% |
| Porsche 911 GT3 R (992) EDR x5 | 0 kg | -0.50% | 98% |
The Porsche 911 GT3 R (992) carries zero weight penalty into Sebring: the cleanest ballast position in the entire GT3 field. With only a modest -0.50% power adjustment and 98% fuel capacity, the 992 is the most favourably balanced GT3 car at this event. The Mercedes-AMG takes the hardest power hit at -1.75%, while the Aston Martin carries the heaviest ballast at 15 kg.
Endurotech Racing Entry List — Sebring 2026
| Class | Car | Entries | BOP Position |
|---|---|---|---|
| GT3 | Porsche 911 GT3 R (992) | 5 cars | Favourable — 0 kg penalty |
| LMP2 | Dallara P217 | 2 cars | Clean — no adjustments |
Team Testing Week — How We Prepared
Ahead of every major endurance event, Endurotech Racing runs a structured team testing week. Drivers met throughout the week in organised team sessions to map fuel consumption per lap, stress-test setup packages across full-length stints, and align all seven cars on pit procedure before race weekend begins. Nothing about Sebring weekend is improvised.
Setup Services We Tested
We evaluated four professional iRacing setup providers to find the optimal Porsche 992 configuration for Sebring’s rough surface and long-stint demands:
- GOSetups.gg — evaluated for qualifying pace reference and lap time ceiling at Sebring
- VRS (Virtual Racing School) — tested for multi-driver adaptability, critical when five different drivers share the same base setup across the team
- HYMO Setups — assessed for long-stint stability, developed specifically with endurance conditions in mind
- GnG (Grid and Go) — used for telemetry data reference and identifying where time is available through Sebring’s technical sections
We do not pick the fastest single-lap setup. For a 12-hour race, consistency and tyre behaviour across laps 10 to 15 of a stint matters more than peak pace. Each package was evaluated on a full stint simulation, measuring car behaviour as fuel burns and tyres wear on Sebring’s abrasive concrete. Our full setup verdict drops in the post-race debrief next week.
Fuel Mapping
- Fuel burn per lap calculated precisely across both the Porsche 992 GT3 R and Dallara P217 during team sessions this week
- Pit strategy windows built from fuel data first. Driver rotation fits around windows, not the other way around.
- A minimum one-lap fuel buffer carried at all times across all seven cars
- Both LMP2 entries benefit from 100% fuel capacity under the clean BOP, giving full flexibility on strategy
Sebring International Raceway — Circuit Guide
Sebring is unlike any other circuit on the iRacing calendar. The track surface is a patchwork of old concrete sections, expansion joints, and bumps that challenge your setup and your concentration across every one of the 12 hours. Understanding what the circuit demands is non-negotiable before you take the start.
- Rough, bumpy concrete demands a setup built around stability over outright downforce
- Heavy braking zones at Turn 1 and Turn 17 — brake fade is a real factor on longer stints if brake bias is not managed correctly
- Fast sweeping sections reward aerodynamic balance and committed driving under sustained load
- No full-course yellow periods — 12 hours of green flag racing means every unplanned stop is pure time loss
- 50 incident point team limit shared across all drivers — clean racing in multiclass traffic is as important as outright pace
- GTP and LMP2 cars will lap the GT3 field multiple times — pre-briefed overtaking protocols are mandatory for every driver
Race Strategy — What to Watch For
Multiclass Coordination
With both GT3 and LMP2 entries operating under the same team banner, Endurotech drivers have a unique advantage: our GT3 drivers know exactly how our own LMP2 cars move through the pack, and our LMP2 drivers know our GT3 pit windows. This internal coordination reduces the risk of intra-team incidents in traffic and is something no setup service can replicate.
The 50-Point Incident Limit
- Between our 2 and 4 th per team they carry shared responsibility for the team incident count
- A 3-second concession to a lapping GTP car costs nothing. A contact-induced repair stop costs 5 minutes and a class position.
- Our spotter calls all concessions. Drivers do not make that decision alone during the race.
Pit Window Execution
- One dedicated engineer per car monitors live timing, fuel delta, and traffic throughout the event
- All pit calls come from the engineer. The driver’s only job on track is driving.
- Handover procedures, brake bias settings, and brake marker references briefed to all drivers before race start
