Choosing the right FIA bucket seat can make a significant difference to both driver comfort and performance on track. Two of the most popular head-supported seats we currently stock and display in our showroom are the OMP RS PT 2 and the Mirco RS1. Both are designed specifically for motorsport use and comply with FIA safety standards, but they approach driver support and sizing in slightly different ways.
For drivers building a track car, rally car, or club-level race car, these two seats often appear on the shortlist. They sit within the same category of fibreglass head-supported bucket seats and are commonly paired with multi-point racing harnesses and HANS devices. However, once you begin looking closer at the seat shapes, dimensions, and driver fitment, you start to notice some important differences between them.
Both seats offer strong lateral support, integrated head protection, and proper FIA homologation, but the internal width, shoulder shape, and overall proportions vary enough that one may suit your driving position or vehicle better than the other. Some drivers prefer the tighter race-focused feel of one seat, while others may find the slightly different proportions of the other seat more comfortable over longer sessions.
In this comparison guide, we will look closely at the OMP RS PT 2 and the Mirco RS1 to help you understand where each seat stands out. We will go through the design, driver fitment, and dimensions of both models so you can get a clearer idea of which one might suit your build and driving style best.
Why Choose a Head Supported FIA Bucket Seat
Head-supported FIA bucket seats are designed for motorsport environments where driver safety and stability are a priority. Unlike traditional bucket seats, these models include extended wings around the helmet area. These side supports help reduce lateral head movement during heavy cornering or in the event of an impact. When used correctly with a helmet and harness system, they form part of a much more controlled and protected driving position.
These types of seats are commonly found in circuit racing, rally, time attack, and other forms of competitive motorsport where the driver is subjected to high cornering forces and sudden directional changes. The combination of deep torso bolsters, high shoulder support, and integrated head restraints helps keep the driver firmly positioned in the seat. This reduces fatigue during longer sessions and allows the driver to focus more on controlling the car rather than bracing themselves in the cockpit.
Head-supported seats are also designed to work alongside modern motorsport safety equipment. Most are compatible with multi-point harness belts and HANS devices, which are commonly required in FIA-regulated events. When paired correctly with the right harness setup and mounting position, the seat becomes a key part of the overall safety system within the vehicle.
Another advantage of these seats is the additional stability they provide in high-performance driving. Even in non-competitive environments such as track days, drivers often notice a significant improvement in confidence and control once they move to a properly fitting motorsport seat. The improved support helps keep the body aligned with the steering and pedal inputs, which can make the car feel more predictable when pushing harder on track.
Mirco RS1 VS OMP RS-PT 2
Mirco RS1
The Mirco RS1 is another head-supported FIA bucket seat that has become popular with club motorsport drivers. It offers a similar level of safety and support but with slightly different proportions and interior shaping.
The RS1 uses a strong fibreglass shell combined with deep side bolsters and head protection wings. One of the things drivers often notice about the Mirco seat is its supportive yet slightly more open seating area compared to some other head-supported seats.
This makes it a good option for drivers who want strong support without feeling overly confined in the seat. The design works well with multi-point harness belts and motorsport safety equipment.
Key features of the Mirco RS1:
- Dedicated for people weighing up to 85kg and height from 165cm to 175cm
- Recommended Driver Height – Under 6ft
- Driver Waist Size – (30″-34″)
- Approval: FIA 8855-1999
- Fibreglass seats
- 5 Harness Slots
- Removable Lumbar & Leg Support
- HANS Compatible
- Weight: 8.2 kg
OMP RS-PT 2
The OMP RS PT 2 is a well-known motorsport bucket seat that has been used in a wide range of race builds. It features a fibreglass shell construction with integrated head protection wings and a deep shoulder support design.
The seat shape provides strong lateral support through the shoulders and torso while keeping the seating position relatively compact. This makes it a popular choice for track builds where cockpit space can be limited.
The RS PT 2 also has carefully shaped leg supports and a comfortable base profile which helps during longer race sessions. It is compatible with multi-point harness belts and designed to work properly with HANS devices.
Key features of the OMP RS PT 2:
- Dedicated for people weighing up to 85kg and height from 165cm to 175cm
- Driver Hight – Under 6ft
- Driver Waist Size – (32″-36″)
- Approval: FIA 8855-1999
- Fibreglass seats

OMP RS PT 2 Seat Dimensions and Fitment
Understanding seat dimensions is essential when choosing a motorsport bucket seat. The OMP RS PT 2 has a relatively compact base width with a supportive shoulder section.
Key dimensions include:
- Overall height approximately 910 mm
- Backrest height approximately 770 mm
- Base length approximately 630 mm
- Base mounting width approximately 290 mm
- Shoulder width approximately 575 mm
- Internal seat width approximately 370 mm
- External base width approximately 470 mm
Because the base is not overly wide, the RS PT 2 often fits well in cars with restricted interior space. This includes smaller track cars where the transmission tunnel and door cards limit seat width.
Drivers who prefer a tighter, more race-focused seating position often find the RS PT 2 suits them well due to its supportive torso shape.
Mirco RS1 Seat Dimensions and Fitment
The Mirco RS1 offers slightly different proportions which can make it a better fit for certain drivers depending on build and comfort preference.
Key dimensions include:
- Overall height approximately 880 mm
- Base length approximately 480 mm
- Shoulder width approximately 565 mm
- Internal seat width approximately 395 mm
- External base width approximately 510 mm
- Backrest width approximately 550 mm
Compared to the OMP seat, the RS1 provides a little more internal width across the seating area. This can make it more comfortable for drivers who feel restricted in narrower bucket seats.
However, the slightly wider base can make fitment more challenging in some vehicles where cockpit space is limited.
See Both Seats in Our Showroom
Both the OMP RS PT 2 and the Mirco RS1 are seats that we keep on display in our showroom. This allows customers to sit in them, compare the shapes directly, and get a proper feel for how each seat supports the body before making a decision.
Bucket seat fitment is very personal. Two seats can look very similar on paper, but the way they feel once you sit in them can be completely different. Shoulder width, hip support, and the angle of the backrest all affect how comfortable the seat will be once installed in the car. Being able to try both seats side by side makes it much easier to understand those differences.
When customers visit the showroom, they can also compare how the head protection wings feel when wearing a helmet. Some drivers prefer a tighter head surround for maximum stability, while others may prefer a slightly more open design. Testing this in person helps avoid ordering a seat that feels too restrictive once it is installed in the vehicle.
Our showroom setup also allows us to discuss mounting options and installation at the same time. We can demonstrate suitable side mounts, explain how the seats align with harness belts, and talk through vehicle fitment considerations. This is particularly helpful for drivers installing head supported seats into smaller cockpits where shoulder width and seat height need to be carefully considered.
If you are unsure which seat shape will suit you best, visiting the showroom and sitting in both models is often the most reliable way to decide. It removes the guesswork and gives you confidence that the seat you choose will be comfortable, supportive, and suitable for your build.

Driver Fitment and Comfort Comparison
One of the biggest differences between these two seats is the way they fit different driver shapes.
The OMP RS PT 2 tends to feel more snug around the torso and hips. Drivers looking for a tight race seat often prefer this style because it locks the body firmly in position during high cornering loads.
The Mirco RS1 has a slightly more open internal width, which some drivers find more comfortable during longer sessions. If you have broader shoulders or prefer a little extra space around the hips, the RS1 may be the better choice.
Trying the seats in person is always the best way to determine which shape suits you.
Vehicle Fitment Considerations
When installing a head supported seat it is important to consider both driver fitment and vehicle space. Head wings, shoulder width, and base mounting points can all affect whether the seat will fit comfortably inside a particular car.
Cars with narrow interiors may favour the slightly slimmer base of the OMP RS PT 2. Vehicles with more cockpit space can comfortably accommodate the Mirco RS1 and its slightly wider internal profile.
Side mounts and seat position also play an important role in achieving the correct driving position.
