REX-03M Design Intent
REX-03M is a good option when the car needs something special but not overly loud. It works especially well with brushed, silver, gunmetal, or soft tinted finishes. The current table spans roughly 4.3 to 9.3 kg depending on size, so smaller fitments favor response while larger fitments add stance and load reserve.
AZ80A-T6 Magnesium Monobloc
This elegant magnesium FE wheel is chosen when lower rotating mass is the point. Width, offset, brake room, bolt pattern, center bore, concavity, and finish are set once the car and tire package are known.
Best On The Right Car
Best for grand tourers, luxury sedans, clean coupes, and owners who want magnesium performance with a more elegant look.
REX-03MBest Fit
Best for grand tourers, luxury sedans, clean coupes, and owners who want magnesium performance with a more elegant look.
01
Lower unsprung mass.
Lower wheel mass can improve steering response, braking feel, acceleration, and suspension control.
02
Performance-specific material.
AZ80A-T6 magnesium is used where the build priority is weight reduction with real structural review.
03
Custom fitment.
Width, offset, bolt pattern, center bore, brake clearance, and finish are confirmed before production.
ApproximateREX-03M Weights
Approximate weight excludes center cap and valve. Final weight changes with width, offset, bolt pattern, brake clearance, load rating, and machining depth.

Forging Profile Option
EnhancedConcavity
LFI concave profiles are built around wheel width, offset, diameter, brake clearance, and forging depth. The goal is to push the face as deep as the car allows, without compromising fitment, caliper clearance, or structural integrity.
Three concavity levelsOffset-sensitive designCost option
Maximum Concave Face
The Maximum Concave Face option is available for selected LFI magnesium forged wheel designs. Depending on wheel width and offset, the face profile can be tuned from mild concave to a deeper spoke drop.
Wider wheels and lower offsets generally allow stronger concavity. Final availability depends on the vehicle body, suspension, brake package, and selected forging blank.
Three Concavity Levels
Concavity is not selected by diameter alone. The final face depth is calculated from the full fitment package.
The exact concavity level is confirmed during fitment planning.
Anti-Slip Knurled Beads
Knurled bead seats can help reduce tire movement during hard acceleration, braking, cornering, drag launches, and sticky tire use.
Annular Reinforcement Ribs
Reinforcement ribs can improve stiffness, stress distribution, and durability where the vehicle load, tire package, or road conditions call for extra reserve.
FAQ
REX-03MQuestions
Is REX-03M a magnesium forged monobloc wheel?
Yes. REX-03M is a magnesium forged monobloc wheel using AZ80A-T6 magnesium alloy as the material route.
