TRS-05Design Direction
A multi-spoke track forged wheel with even load distribution and clear view of the brake package. Designed for the heat, load and repetition of circuit driving.
Track-focused forged architecture
The face profile, brake clearance and machining depth are drawn around the brake envelope.
Fitment locked before machining
Every dimension is confirmed around your car's actual brake package, tyre size and load target - not adapted from a catalogue.
Built ForCircuit Load
Track use changes the load signature on a wheel. Repeated heat cycles. Sustained lateral load. Heavy braking from high speed. Tyres that grip harder than road compounds. A wheel that is strong enough for the street may not stay composed through a full track day.
TRS wheels are reviewed against track-duty loads: higher cornering forces, repeated brake heat, tyre slip under acceleration. The load target is confirmed against your car's circuit weight, tyre compound and intended pace, not a blanket rating.
Optional track features:
Knurled anti-slip bead seats - textured bead contact surfaces that reduce tyre slip under hard acceleration and braking.
Annular reinforcement ribs - circumferential ribs inside the barrel that increase barrel stiffness without adding face-side mass.

ConcavityAnd Track Options
These optional forged wheel details are confirmed during fitment planning for TRS-05 builds where face depth, tire slip resistance, or structural reinforcement needs to be considered.
Forging Profile Option
EnhancedConcavity
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.
19-22 inch applicationsThree concavity levelsOffset-sensitive designCost option
Maximum Concave Face
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.
Three Concavity Levels
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.
The exact concavity level is confirmed during fitment planning. LFI checks the target wheel size, brake envelope, center profile, and vehicle clearance before production.
Deep Concave for High-Offset Cars
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.
Fitment Still Comes First
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.
Deep Concave Forging Example
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.
Cost option: Enhanced concavity and deep concave blank selection are optional upgrades. Final availability depends on wheel size, brake clearance, vehicle platform, and the selected LFI wheel model.
Performance-Friendly Detail Options
Anti-Slip Knurled Beads
Knurled bead seats can help reduce tire movement on higher-grip applications, including track use, hard braking, drag launches, and sticky tire setups.
Annular Reinforcement Ribs
Reinforcement ribs can add barrel rigidity where the final specification, road conditions, tire package, or vehicle load calls for extra reserve.

Where TRS-05Makes Sense
Dedicated track cars
Cars built or modified for circuit use. Roll cages, sticky tyres, big brakes - the wheel is the final component in a track-focused build.
Time attack and competition
Cars that are timed. Where wheel mass, stiffness and reliability under repeated heat cycles are measured in tenths.
Advanced track-day builds
Porsche 911, BMW M3/M4, GR86, Civic Type R. Platforms where track-day pace justifies track-focused wheels.

Actual GoogleReview Excerpts
Brock Mitchell
★★★★★LFI built a set of forged wheels for my track car. The fitment was spot-on. Brake clearance was handled without spacers. The weight difference was immediately noticeable on turn-in.

★★★★★Third set from LFI. Each time the fitment has been perfect. The engineering conversation before ordering is what sets them apart from catalogue wheel sellers.
Read on GoogleTRS-05Questions
Is TRS-05 built to order?
Yes. Every TRS-05 set is forged and machined around your specific vehicle: diameter, width, offset, brake clearance, load target, bolt pattern, centre bore, concavity and finish are all confirmed before production.
How much does TRS-05 weigh?
See the approximate weight table above. Final weight depends on your width, offset, bolt pattern, brake clearance, load target and finish. Verified weight is confirmed on the finished wheel.
Can TRS-05 clear big brakes without spacers?
Yes, when the final specification is drawn around the actual brake package. LFI checks spoke shape, backpad, barrel clearance, balancing-weight clearance, centre profile and offset before production.
Can TRS-05 be used for track or fast-road driving?
Yes. LFI reviews vehicle mass, tyre package, braking load, road surface, load rating, bead-seat needs and optional reinforcement details before confirming a fast-road or track specification.
What information does LFI need to start a TRS-05 build?
Share the vehicle model, current wheel and tyre sizes, brake package, ride height, intended use, stance direction, finish direction and any load or track-use requirements.
Can I choose custom finishes?
Yes. LFI can quote gloss, satin, brushed, polished, black, silver, bronze, body-colour and selected custom finishes depending on the final specification and production route.
Does TRS-05 include warranty?
Yes. TRS-05 is covered for 2 years upon delivery or collection against defects in structural integrity, subject to LFI's full warranty terms and exclusions.
How does LFI support Singapore, USA and international orders?
Singapore builds can be planned directly with LFI. US and international customers can order in English through WhatsApp or email by sending vehicle photos, brake details, current wheel and tyre sizes, ride height, fitment goals, intended use and delivery ZIP/postcode.
