The most track-focused wheel LFI builds. Every feature is oriented around circuit performance: knurled anti-slip bead seats, annular barrel reinforcement, track-specific load review, and weight reduction prioritised over visual complexity. For drivers who measure wheels by data, not design.

The face profile, brake clearance and machining depth are drawn around the brake envelope.
Every dimension is confirmed around your car's actual brake package, tyre size and load target - not adapted from a catalogue.
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.
Strong match for GR Yaris, GT86/BRZ, Civic Type R, MX-5, Lotus, and compact track cars that reward low unsprung weight.
Fast response.
Less rotating and unsprung mass helps the car feel more eager on steering, braking, and acceleration.
Real brake planning.
Spoke profile, center pad, and inner clearance are checked around the actual brake package.
Custom stance without guessing.
Width, offset, bolt pattern, center bore, and finish are confirmed before production.
TRS-02 V2 starts with a dense 6061-T6 forged aluminium blank, then gets CNC-machined into a one-piece forged monobloc wheel. Compared with cast or flow-formed alloy rim wheels, this gives LFI more room to reduce weight while keeping strength in the hub, spokes, bolt seats, and barrel transitions.
TRS-02 V2 is not locked to one generic wheel size. Diameter, width, offset, bolt pattern, center bore, brake clearance, and finish are chosen around your car. That matters for GR Yaris, GT86 / BRZ track setups, EV street builds, big-brake conversions, and flush performance fitments.
A lightweight forged wheel is not just about the number on the scale. TRS-02 V2 is built to keep response sharp while still giving the tire, brakes, hub, and barrel the support they need.
CNC pocketing.
Material is removed from low-stress zones to reduce rotating mass without weakening the working structure.
Spoke-to-barrel support.
The spoke root and barrel transition are treated as structural zones, especially for track tires and higher-load vehicles.
Brake-first fitment.
Inner clearance and spoke shape are checked before production so the wheel suits the car, caliper, tire, and stance target.
Confirmed TRS-02 V2 customer cases are shown here to demonstrate real forged-wheel fitment across compact AWD performance and rear-wheel-drive track-style platforms.

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, including negative-offset builds 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 19×8.5J ET42 reference example.

Anti-slip knurled beads are small machined grooves on the inner bead seat of the wheel. They increase mechanical grip between the tire and rim, helping reduce tire slip during hard acceleration, braking, cornering, track use, or low-pressure off-road driving.
Under heavy load, a tire can rotate slightly on the wheel before the car itself moves. That tiny slip can affect wheel balance, alignment marks, steering response, and repeatability during aggressive driving.
Knurled beads add controlled surface bite at the bead seat, helping the tire stay locked in position without changing the exterior look of the wheel.
This option is useful for track cars, drag builds, heavy EVs, off-road setups, and high-grip tire packages where tire movement on the rim can become a real-world issue.
It is a functional machining upgrade, not a cosmetic styling option.
Annular reinforcement ribs are structural ridges added to selected areas of a forged wheel to improve stiffness, load distribution, and durability without simply making the wheel unnecessarily heavy.
Instead of relying only on extra material thickness, reinforcement ribs allow the wheel structure to resist flex more efficiently. The rib geometry helps spread load across the wheel section and supports areas that see repeated stress during road use, cornering, braking, and impact loading.
This is especially useful on performance, EV, SUV, off-road, and track-focused builds where wheel stiffness and long-term fatigue resistance matter.
A forged wheel should not be strong only on paper. It needs to hold its shape under real driving loads. Reinforcement ribs help maintain rigidity, reduce unwanted barrel or spoke-area flex, and improve the wheel’s ability to handle demanding use without adding excessive weight.
The result is a cleaner balance between strength, durability, and forged-wheel performance.
