If you have ever spent time in the Subaru community, you have seen them. They are the iconic, five-spoke alloy wheels that defined the look of the GR/GV-chassis STI from 2008 to 2014. Sleek, strong, and instantly recognizable, these OEM STI wheels are some of the most sought-after factory wheels ever produced. But what makes them so special, and more importantly, will they fit your car? This guide dives deep into the technical details, model year applications, and fitment compatibility of the legendary WRX STI 5 spoke OEM wheels, providing you with everything you need to know before you buy, sell, or install a set.
Walking through the paddock at a Subaru track day, you will see a sea of these wheels. Their design is not just about aesthetics; it is a product of performance engineering. The five-spoke pattern is clean and open, designed to maximize brake cooling for the legendary STI Brembo calipers. Unlike more complex aftermarket designs, these Subaru 5 spoke wheels are remarkably easy to clean, a fact any owner who has dealt with brake dust will appreciate.
A key piece of trivia that often circulates on forums is the manufacturer. While many assume they are made by BBS, the standard wheels on the 2008-2014 STI (non-limited trims) were actually produced by Enkei, a world-renowned wheel manufacturer known for its high-quality casting and forging processes. So, when you ask, "Are STI 5-spoke wheels made by Enkei?" the answer for this specific generation is a resounding yes. This partnership with Enkei resulted in a wheel that is both lightweight and incredibly strong, a perfect match for the STI's rally-bred DNA.
Before you even think about fitment, you need to know the hard numbers. Here are the definitive WRX STI wheel specs for the Enkei-made 5-spoke wheels.
| Specification | Measurement |
|---|---|
| Wheel Diameter | 18 inches |
| Wheel Width | 8.5 inches |
| Bolt Pattern (PCD) | 5x114.3 Subaru |
| Offset | +55 mm |
| Center Bore | 56.1 mm |
| Weight (Approximate) | 24.5 lbs (11.1 kg) |
| Factory Tire Size | 245/40R18 |
Bolt Pattern (5x114.3): This is one of the most critical pieces of information. The bolt pattern, or Pitch Circle Diameter (PCD), is 5x114.3, meaning there are 5 lug nuts spaced evenly on a 114.3mm circle. This is a crucial differentiator. Earlier STI models (2004-2007) and base model WRXs for many years used a 5x100 bolt pattern. This 5x114.3 Subaru pattern is specific to later STI models and is a key factor in STI wheel interchange.
Offset (+55): The offset is the distance from the wheel's centerline to its mounting surface. A +55 offset means the wheel sits relatively tucked-in, ensuring proper clearance with the struts and fenders on the vehicle it was designed for. This is a vital number for understanding fitment on other models.
Center Bore (56.1mm): The center bore on STI wheels is 56.1mm. This is a hub-centric design, meaning the wheel is precisely located on the hub by this center bore, not just the lug nuts. For a vibration-free fit on vehicles with a different hub size, you will need hubcentric rings.
These specific WRX STI 5 spoke OEM wheels were standard equipment on the Subaru Impreza WRX STI for model years 2008 through 2014. This covers both the sedan and hatchback body styles of the GR/GV chassis. They are often referred to as the 2011 STI wheels, but the design was consistent across this entire generation.
The official Subaru part number for these wheels is 28111FG030. You may also see variations like 28111FG000 or others, but 28111FG030 is the most common part number associated with this specific design. If you are looking at a used set, finding this part number stamped on the inside of the wheel is a great way to verify authenticity.
This is the core of the article, answering the burning question: "Will STI wheels fit a regular WRX?" or other Subarus. The answer is complex and depends entirely on the recipient vehicle.
These vehicles share the same 5x114.3 bolt pattern and have similar hub and strut clearances, making them direct bolt-on candidates (always double-check clearance with your specific tire size):
This is a very common swap. The 2008-2014 WRX uses a 5x100 bolt pattern, so the STI wheels will not bolt on directly. To make them fit, you need an adapter that changes the bolt pattern from 5x100 to 5x114.3. This requires high-quality, hub-centric adapters that are typically 20-25mm thick. This will effectively change the wheel's offset to around +30 to +35mm, which will push the wheel outwards. With the factory 245/40R18 tire, this can cause fender rubbing, especially if the car is lowered. Rolling the fenders is often necessary.
The 2015+ WRX uses a 5x114.3 bolt pattern, so the bolt pattern is correct. This directly answers the common query, "Will 2011-2014 STI wheels fit a 2015+ WRX?" Yes, they will bolt on. However, the 2015+ WRX has a smaller stock wheel offset (typically +55 on a 8.5" wheel is fine, but the hub area may have slight clearance differences). The most critical item is the center bore. The 2015+ WRX has a 56.1mm hub, so the STI wheels are a perfect hub-centric match. This is generally considered a straightforward and excellent swap.
So, "Can I put STI wheels on a Forester or Outback?" For older models (SF-SJ Forester, 2000-2014 Outback) with a 5x100 pattern, you face the same issue as the 2008-2014 WRX: you need 5x100 to 5x114.3 adapters. For newer Foresters and Outbacks (2015+) that use a 5x114.3 pattern, they become a direct bolt-on. However, the factory STI tire size (245/40R18) may be too tall or wide for the wheel wells of these SUVs, potentially causing severe rubbing, especially when turning or under compression. A smaller tire size or significant fender modification is often required.
The factory-equipped tire size for these wheels is 245/40R18. This is a great balanced size for grip and handling. However, when using these wheels on a non-STI vehicle, you may need to adjust the tire size to prevent rubbing. Common alternative sizes include:
Always test fit a wheel and tire assembly and check clearance at full lock and full suspension compression before driving.
With the popularity of these wheels, replicas exist. Here is how to tell if my STI wheels are authentic OEM:
The value of a used set of OEM STI 5-spoke wheels varies greatly based on condition. A set with curb rash might fetch $600-$800, while a pristine, unmounted set can sell for $1200-$1500 or more, especially if they include the original center caps.
When installing these wheels on any vehicle, follow these best practices:
The WRX STI 5 spoke OEM wheel is a modern classic. Its timeless design, robust construction by Enkei, and performance-oriented specs make it a fantastic choice for Subaru enthusiasts looking to upgrade their vehicle's look and performance. While OEM wheel fitment can be a complex puzzle, understanding the core specifications of bolt pattern, offset, and center bore empowers you to make the right decision. Whether you are bolting them onto an STI, adapting them to an older WRX, or making them fit a Legacy, these wheels are a piece of Subaru history that continues to deliver.
