Subaru Forester XT
Forged wheel sizing, stance, brake-clearance planning, 5x100 PCD references, 56.1 center-bore references, recorded customer specifications, and street-ready engineering checks for Subaru Forester XT owners.
Recorded fitment data gives this guide a working engineering baseline; installed-car photos can be added once the build is photographed.
This guide helps Subaru Forester XT owners choose forged wheels with the right stance, tire support, brake clearance, and road manners. The goal is simple: a wheel that looks right, fits properly, and feels sharp on the actual car.
Balanced sizing for daily driving, tire availability, and clean fender clearance.
Spoke profile, barrel shape, and backpad are reviewed around the exact brake package.
Lower unsprung mass can sharpen steering, braking feel, and ride control.
| Area | Guide value | Fitment note |
|---|---|---|
| PCD | 5x100 | Confirm exact vehicle before machining. |
| Center bore | 56.1 | Machine hub-centric to the confirmed car. |
| Wheel sizes | 18x7.5 ET37 | Review tire, brake, fender and ride height together. |
| Wheel models | MF36 based on 3302021_08 | Face profile depends on brake and load target. |
This recorded 2017 Subaru Forester XT specification anchors the guide around 18x7.5 ET37 MF36 based on 3302021_08 with 5x100 / 56.1. LFI still confirms tyre shoulder, brake clearance, ride height and load target against the actual car before machining.
This fitment is kept as a real specification reference and can receive customer photos later.
The primary row comes from an LFI customer fitment record. Alternate rows are reference directions only, then LFI still checks brake template, tire shoulder, load target, and the actual ride height before production.
| Direction | Wheel size | Wheel model | Best for | Notes |
|---|---|---|---|---|
| Primary | 18x7.5 ET37 | MF36 based on 3302021_08 | Real LFI build record | LFI customer fitment record. Confirm tire shoulder, brake template, ride height, and final offset. |
| Alternate | Same diameter, +0.5 in width, offset within 5 mm | LFI CSF1 V3 Racing Forged Wheel | More visual aggression | Reference benchmark. Verify tire shoulder, brake template, ride height, and fender clearance before production. |
| Additional | One inch larger diameter with conservative width | LFI CSF3 V2 Racing Forged Wheel | Show-oriented street fitment | Reference benchmark. Confirm tire diameter, load rating, brake clearance, and road-use comfort first. |
Wheel fitment is more than diameter and offset. LFI reviews vertical load, braking and drive torque, spoke-root behavior, hub-pad stress, bolt-seat stress, and combined load cases before final production.
For this guide, LFI uses an aggressive compact SUV rear-axle working baseline of 1450 kg, or 725 kg per wheel. The preferred customer-facing target in this table is 890 kg per wheel when the wheel family allows it.
Wheel strength is not only vertical load. LFI also reviews acceleration, braking, cornering, potholes, tire grip, hub-pad stress, bolt-seat stress, spoke-root stress, and rim-barrel torque reaction against an approximately 1,600 Nm per wheel static torque load target.
If you want the manufacturing side of the process, LFI's How LFI Wheels Are Made page shows the design, forging, CNC machining, finishing, and QC logic behind a custom forged wheel before it ever reaches the car.
| Wheel load rating | Per-axle equivalent | Margin vs axle baseline | Status | How LFI positions it |
|---|---|---|---|---|
| 690 kg | 1380 kg per axle | -5% vs 725 kg/wheel | Low reserve | Use only after exact axle data, tire load, and duty cycle are confirmed. |
| 790 kg | 1580 kg per axle | +9% vs 725 kg/wheel | Low reserve | Use only after exact axle data, tire load, and duty cycle are confirmed. |
| 890 kg | 1780 kg per axle | +23% vs 725 kg/wheel | Preferred | Road-use, fast-road, and daily forged applications with useful axle-load reserve. |
| 950 kg | 1900 kg per axle | +31% vs 725 kg/wheel | Extra reserve | Extra reserve for harsher roads, heavy tires, high-speed use, payload, or aggressive duty cycles. |
| Validation load case | Reference basis | Suggested LFI target | Why it matters |
|---|---|---|---|
| Radial vehicle load | Vehicle mass, passengers, tire package, and selected wheel load target | 890 kg preferred target | Represents vehicle mass and repeated road loading. |
| Torque load | Conservative 1g dry braking check with 60% front bias | ~1,600 Nm per wheel | Loads the hub pad, bolt seats, spoke roots, and rim barrel. |
| Cornering load | Lateral force from road grip, sticky tires, and fast-road or track use | Application-specific | Shows how the wheel behaves when the chassis loads sideways during aggressive cornering. |
| Combined static load case | Radial load + torque load + cornering load | Application-specific | More realistic than isolated vertical checks because real driving loads rarely occur one at a time. |
Engineering Article
For forged wheel applications, vertical load is only one part of the engineering picture. LFI also reviews spoke-root stress, hub-pad loading, bolt-seat behavior, rim-barrel stress, and combined static road-load cases where relevant.

Send the model year, trim, brake package, tyre target, ride height, alignment notes, PCD, hub bore, hardware seat, centre-cap plan, finish, load target and intended use.
Yes. LFI supports local Singapore and Malaysia customers and ships forged wheels internationally with fitment consultation.
Yes. The photos are fitment references. LFI can quote gloss, satin, brushed, polished, bronze, black, silver, and custom finishes depending on the wheel design.
No. The photographed setup is a proven reference point, but LFI can adjust width, offset, concavity, finish, and tire pairing around your car and goals.
Brake clearance depends on the caliper template, barrel profile, spoke shape, backpad, and final offset. LFI checks these before machining.
Yes. A comfort-biased setup can use a more conservative width, sensible offset, and tire sizing with enough sidewall for road use.
Yes, but fender clearance, steering clearance, tire shoulder, ride height, and alignment need to be checked together.
Often yes, if the cap diameter, clip style, pocket depth, and face profile are planned before production.
Yes. Square setups are popular when owners want easy tire rotation, predictable handling, and a clean road-use package.
Yes. Staggered setups can work when the platform, tire diameter, and drivetrain requirements support it.
Two tires with the same printed size can sit differently. Shoulder shape affects fender clearance, steering clearance, and the final stance.
Offset only tells part of the story. Width, tire size, brake clearance, hub geometry, concavity, and ride height all affect whether the setup works.
Yes. LFI supports international forged-wheel orders and can prepare fitment consultation remotely before production.
