TRS-05 Design Intent
TRS-05 suits owners who want a wheel that can handle weekday driving, weekend mountain roads, and occasional track use without looking too stripped out. The current table spans roughly 4.8 to 11.9 kg depending on size, so smaller fitments favor response while larger fitments add stance and load reserve.
Forged 6061-T6 Aluminium Monobloc
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.
Best On The Right Car
Good for hot hatches, compact sedans, modern coupes, and owners moving from OEM wheels to a lighter forged setup.

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.
Fitment PlanningFor Your Build
USA and international orders
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-05 Racing specification remotely, supports DDP shipping where available, and coordinates production updates before dispatch.
Track CarsRoad Cars
TRS-05 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.
Compact Performance
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.
European Track And Fast Road
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.
High-Load Road Cars
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.

TRS-05 Questions
Is TRS-05 built to order?
Yes. LFI confirms width, offset, bolt pattern, center bore, brake clearance, finish, load rating, and optional machining details before production.
Can LFI estimate the final wheel weight?
Yes. The table uses existing model-specific weight data where available, then estimates nearby sizes for planning. Final weight is confirmed after the actual specification is engineered.
Can this wheel support track or fast-road use?
Yes. LFI reviews tire package, braking load, vehicle mass, surface conditions, and the selected load rating before confirming a track or fast-road build.
Can I choose enhanced concavity?
Yes, where the wheel size, offset, brake package, and forging blank allow it. Enhanced concavity is an optional cost upgrade and must be checked per vehicle.
Can I choose custom finishes?
Yes. LFI can quote gloss, satin, brushed, polished, black, silver, bronze, body-color, and selected custom finishes depending on the wheel design and production route.
