Custom forged wheels Singapore
LFI plans each TRS-03 Racing set from Singapore around the car's brake package, tyre target, ride height, offset window, load target, centre bore, TPMS transfer and finish direction.
TRS-03 keeps the Performance Series focused on driver feel, with an open forged design that suits brake-heavy cars and track-day setups.

TRS-03 is a good call when you want the brake package to breathe visually and physically. It feels right on cars that run heat, grip, and repeated hard braking. The current table spans roughly 4 to 11.1 kg depending on size, so smaller fitments favor response while larger fitments add stance and load reserve.
Each wheel is cut from forged 6061-T6 aluminium and finished to suit the build. Width, offset, bolt pattern, center bore, concavity, and color are selected after the car and tire setup are known.
Works for Civic Type R, GR86/BRZ, BMW M2/M3, Porsche Cayman/Boxster, and track-oriented street cars.
These product views show the design language for TRS-03. Final width, offset, center bore, load rating, finish, and concavity are confirmed around your car before production.
TRS-03 is shaped for customers who want a performance forged wheel with enough brake clearance and spoke structure for real road or track use.
This track-focused open wheel is ordered around the car's tire width, brake package, ride height, offset target, and finish direction.



Approximate weight excludes center cap and valve. Final weight changes with width, offset, bolt pattern, brake clearance, load rating, and machining depth.

These optional forged wheel details are confirmed during fitment planning for TRS-03 builds where face depth, tire slip resistance, or structural reinforcement needs to be considered.
LFI concave profiles are built around the relationship between wheel width, offset, diameter, brake clearance, and forging depth. The goal is simple: push the face as deep as the car allows, without compromising fitment, caliper clearance, or structural integrity.
The Maximum Concave Face option is available for selected LFI Performance Series, Supreme Concave Series, and Project Speciale forged wheel designs. Depending on wheel width and offset, the face profile can be tuned from mild concave to a much deeper spoke drop.
Wider wheels and lower offsets generally allow stronger concavity. In aggressive applications, fitments can extend to very low offsets where the vehicle body, suspension, and brake package allow it.
Concavity is not selected by diameter alone. The final face depth is calculated from the full fitment package: rim width, offset, brake clearance, vehicle platform, and the chosen forged wheel design.



Some high-offset vehicles do not naturally allow a deep spoke profile because the wheel face must sit further outward to clear the hub and brake package. For these applications, LFI can offer a specialized heavy-duty blank option that creates a more pronounced concave look while keeping the fitment usable.
This is especially useful for cars where the customer wants a stronger visual stance but still needs proper inner clearance, brake clearance, and road-use reliability.
Deep concavity must be balanced against caliper clearance, suspension clearance, fender position, tire width, and the actual offset range the vehicle can accept. The most aggressive face is not always the best face for every car.
LFI will always prioritize a correct forged-wheel fitment over forcing a face profile that creates clearance problems.
The deep concave forging concept shown below demonstrates how a pronounced face profile can be achieved even on a relatively high-offset fitment, using a 19x8.5J ET42 reference example.

Knurled bead seats can help reduce tire movement on higher-grip applications, including track use, hard braking, drag launches, and sticky tire setups.
Reinforcement ribs can add barrel rigidity where the final specification, road conditions, tire package, or vehicle load calls for extra reserve.
LFI plans each TRS-03 Racing set from Singapore around the car's brake package, tyre target, ride height, offset window, load target, centre bore, TPMS transfer and finish direction.
US and international customers can order in English through WhatsApp or email. Send vehicle photos, brake details, current wheel and tyre sizes, ride height, fitment goals, intended use and delivery ZIP/postcode. LFI confirms the TRS-03 Racing specification remotely, supports DDP shipping where available, and coordinates production updates before dispatch.
TRS-03 Racing: Racing forged models fit cars that need brake clearance, lower unsprung mass and predictable tyre support. LFI selects the load target and face profile around the exact platform.
GR86 / BRZ, Civic Type R, GR Yaris, MINI and MX-5 builds reward low mass, brake clearance and precise wheel position rather than a catalogue offset guess.
BMW M2 / M3 / M4, Porsche Cayman / 911, Audi RS and Mercedes-AMG cars need offset accuracy, caliper clearance and tyre support to work as one system.
EVs, larger sedans and heavier performance cars can use an LFI racing design when the load rating, tyre package and centre profile are reviewed before production.
