GT4 in iRacing generates a recurring community question: is it actually worth buying? The cars are priced the same as everything else. The class exists with official series. But GT4 sits in an odd middle position. It falls between the more popular GR86 and MX-5 entry-level cars and the full GT3 grid, and it is not always obvious where it fits.

Here is what you actually get with GT4, who it is for, and when you should skip it.
What GT4 Racing Actually Offers
GT4 cars in iRacing are real-world production-based race cars with less downforce and less power than GT3. The class includes cars like the BMW M4 GT4, Aston Martin Vantage GT4, and Ginetta G55 GT4. The physics are more demanding than the GR86, but less unforgiving than GT3.
The racing format is typically mixed-class endurance or sprint racing. GT4 appears in official series alongside GT3 in multiclass events, which is one of its real draws. You get a taste of multiclass structure without competing at full GT3 pace. Managing gaps, reading traffic, and pacing yourself in a mixed field is a skill that carries over everywhere.
The official iRacing GT4 series run on a seasonal schedule. Grid sizes and split depths vary by season. GT4 typically holds solid enough following to get clean races during peak hours in most regions.
Best GT4 Cars in iRacing
Not all GT4 cars are equal in iRacing. Which one you buy affects your experience significantly. Community consensus points to a few standouts.
BMW M4 GT4 is generally considered the best all-around choice. It has a good balance of grip and power, is competitive in most series, and rewards clean technical driving.
Aston Martin Vantage GT4 is popular for road courses with sweeping corners. It has a distinctive feel compared to the BMW but is well-liked by drivers who put time into it.
Ginetta G55 GT4 is an older model and less commonly recommended for new GT4 buyers. It has a dedicated community of drivers who know it well.
If you are buying one car to compete in official GT4 series, the BMW is the safest starting point.
How GT4 Compares to Other Options
The core question is whether GT4 makes sense instead of going straight to GT3 or staying in the GR86 and MX-5 longer.
GT3 is the most active and competitive road racing class in iRacing. If your goal is to race GT3, the fastest path is to get into a GT3 car now. The GT4 class has fewer active series. Time spent in GT4 is time away from building your GT3 baseline.
The argument for GT4 is that the step from GR86 to GT4 is smaller than the jump to GT3. If you have struggled with car control and are not ready for GT3’s mechanical grip and aero load, GT4 is a valid intermediate step. Some drivers use it specifically for multiclass endurance events.
The argument against GT4 is that its series are thinner than GT3. In some time zones, finding a well-populated GT4 split is harder than finding a GT3 race at the same hour.
When You Should Buy GT4
Buy GT4 if you want multiclass endurance racing and prefer the slower class while you learn pace management. The class handles the mixed-field experience well. Racing clean alongside GT4 rivals while managing GT3 cars lapping you is a genuinely useful skill.
Buy GT4 if you are genuinely interested in one of the specific cars. Racing it in a series context is different from time trialing alone.
Consider skipping GT4 if your goal is the main GT3 sprint grid. There is no specific multiclass draw for you. The time and money are better spent in GT3. The series depth, schedule volume, and community are all stronger there.
GT4 in iRacing is worth it for specific drivers. If you want multiclass endurance racing with a realistic step-up car, it delivers. Drivers targeting the GT3 sprint grid will probably get more value from skipping it. The class is not dead, but it is not the most efficient progression step for most people.
