BalancedRacing Forged
REX-06 V2 is the wheel for customers who want the classic LFI multi-spoke forged look with real fitment engineering behind it. The core trick is not a flat spoke face: the spokes are treated as I-beams, then aggressively pocketed through the side so unused material leaves while the main load path stays purposeful.
I-beam spoke logic
The spoke section carries load like a beam: flanges and the main web do the useful work, while lower-value side mass is reduced through pocketing.
Side-through pocketing
REX-06 V2 uses aggressive side-through beam pocketing to reduce rotating mass without turning the spoke into a thin decorative strip.
Built around the car
PCD, centre bore, width, offset, caliper envelope, load target, tyre size and finish are confirmed before machining.
Light WhereIt Can Be Light
REX-06 V2 does not make every build chase the absolute minimum weight. It keeps the better rule: remove unnecessary mass while preserving the load path around the hub, spoke roots, bolt seats, brake-side clearance and barrel transition.
The I-beam idea matters because a spoke does not need the same amount of material everywhere. REX-06 V2 keeps material where the beam is doing useful work, then uses side-through pocketing to cut away mass from the side of the spoke section. The result is a more purposeful stiffness-to-mass relationship than a plain thick spoke.
ηbuild = useful stiffness / finished wheel mass
Specification note
The principle is simple: remove material where it is not doing useful work, then confirm the finished wheel around the actual car. Diameter, width, offset, brake clearance, load target, tyre choice and finish all shape the final drawing.
Lightweight PocketMachining
REX-06 V2 uses targeted relief cuts and open spoke windows to remove non-structural mass, sharpen the wheel face, and show more of the brake package without making the design look flat.

These REX-06 V2 studio files show the wheel away from the car so the spoke windows, side pocketing, rim transition and finish can be read more clearly.
ApproximateREX-06 V2 Weights
Use this table as a planning reference, not a universal promise for every build. The 17x7J REX-06 V2 reference specification is approximately 6.15 kg / 13.6 lb per wheel. Final mass changes with width, offset, brake clearance, bolt pattern, load target, finish and machining depth.

REX-06 V2 vsTypical Lightweight Forged Wheels
REX-06 V2 is not just a light-looking multi-spoke wheel. Its value is in how the I-beam spoke shape, side-through pocketing, brake clearance and final fitment work as one specification.
| Decision area | Typical aftermarket approach | REX-06 V2 direction |
|---|---|---|
| Design intent | Often selected for a lightweight look or a catalogue fitment that broadly clears the car. | REX-06 V2 is positioned as a balanced racing forged design: clean multi-spoke face, real weight reduction, and fitment drawn around the car. |
| Spoke architecture | May rely on simple spoke thinning, visual windows or decorative machining without a clear beam logic. | I-beam spoke logic keeps material along the useful load path, then uses side-through pocketing to remove lower-value side mass. |
| Pocket machining | Relief cuts can be shallow styling details or hidden where the customer cannot read the engineering intent. | Aggressive side-through beam pocketing is visible on the car, showing the brake package while reducing mass in the spoke shoulder. |
| Brake clearance | Generic offsets can need spacer correction when caliper clearance, face profile and tyre position do not line up. | Width, offset, centre bore, caliper envelope, spoke profile and tyre position are planned together before machining. |
| Best use case | Style-led road builds or broad aftermarket replacements where the wheel is mostly a visual upgrade. | Road, fast-road and track-minded builds where lower mass, brake room, tyre support and a clean motorsport face all matter. |
Width, OffsetAnd Brake Clearance
REX-06 V2 should not be selected by diameter alone. The best result comes from matching wheel width, offset, centre bore, spoke shape, brake package, tyre size and ride height as one package.
Road and fast-road builds
For daily and fast-road use, LFI usually prioritises clean stance, practical tyre support, brake clearance, hub-centric machining and a load target that fits the car.
Track-minded builds
For sticky tyres, hard braking or circuit use, LFI can review stronger load targets, knurled beads, reinforcement ribs and tyre slip behaviour before production.
Cars ThatMake Sense
REX-06 V2 works best where a clean motorsport face, low mass and exact fitment matter more than a loud novelty design.
Compact performance
MINI F56 / F57, Toyota GR86, Toyota GT86 ZN6, Civic Type R FL5, MX-5 ND and MX-5 NC builds reward lower unsprung mass and exact tyre support.
European performance
Porsche 911, Cayman / Boxster, BMW M2 G87, BMW M3 / M4 G80 G82, Audi RS5 and Mercedes-AMG GT builds need brake clearance and offset accuracy to work together.
OEM+ road cars
Volkswagen Golf GTI / Golf R, Audi A5 / S5 / RS5, BMW 3 Series G20, Lexus IS and similar road builds suit a timeless forged-wheel look rather than a one-season trend.

I reached out to LFI for a set of wheels for my BMW X3M. I was looking for a clean motorsport look with an ultimate goal of lightweight. After some back and forth I landed on a set of TRS01 in a 20"/18" combo. Delivery took roughly 7.5 weeks from the date of my order and everything arrived sound.

Fantastic designs, even greater people behind the company. Kevin and Joshua are amazing people who give really good advice on the looks, cuts, sizing and offsets. They are good with how to build the best mechanically appropriate rims for your car.

Fantastic designs, quality, and delivery time. This is the second set of custom rims I've made with them and the results are awesome both times. The fitment is always perfect. So, no need for spacers.

REX-06 V2 Technical FAQ
What is LFI REX-06 V2?
REX-06 V2 is a made-to-order 6061-T6 monoblock forged wheel with a balanced multi-spoke racing design. LFI specifies width, offset, centre bore, PCD, brake clearance, load target, finish and tyre pairing around the car.
How is REX-06 V2 different from REX-0R Superleggera?
REX-06 V2 is the more versatile multi-spoke racing forged wheel direction. Its weight-saving character comes from I-beam spoke shaping and side-through beam pocketing. REX-0R Superleggera is the more extreme lightweight architecture. REX-06 V2 is easier to place on a wider range of road, fast-road and track-inspired builds.
What does I-beam spoke shaping mean on REX-06 V2?
The REX-06 V2 spoke is treated like a beam rather than a flat decorative plate. Material is kept along the load path and around the spoke flanges, while lower-value side mass is pocketed away to improve stiffness per gram.
What is side-through beam pocketing?
Side-through beam pocketing is the visible and structural removal of excess material from the side of the spoke beam. On REX-06 V2, this helps reduce rotating and unsprung mass while keeping the main spoke path, hub transition and rim connection purposeful.
How heavy is REX-06 V2?
Final weight changes with diameter, width, offset, bolt pattern, brake clearance, load target and machining depth. A 17x7J REX-06 V2 reference specification is approximately 6.15 kg / 13.6 lb per wheel.
What sizes can REX-06 V2 be built in?
REX-06 V2 is planned across 16 to 21 inch applications. Width, offset, centre bore, bolt pattern and brake clearance are confirmed per vehicle before production.
Which cars suit REX-06 V2?
REX-06 V2 suits compact performance cars, lightweight road cars, Porsche 911, BMW M, Mercedes-AMG, Audi S and RS, Lexus F, MINI, GR Yaris, GR86, GT86 and clean Japanese or European performance builds.
Can REX-06 V2 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 REX-06 V2 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.
Can REX-06 V2 use enhanced concavity?
Yes, where the wheel width, offset, brake package and forging blank allow it. Concavity is balanced against caliper clearance, suspension clearance, tyre position and structural reserve.
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 REX-06 V2 include warranty?
Yes. LFI's warranty page states that Founder's Edition forged wheels are covered for 2 years upon delivery or collection against defects in structural integrity, subject to the full warranty terms and exclusions.
What information does LFI need to start a REX-06 V2 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. LFI uses that brief to propose the wheel specification.
