Extreme Performance Custom Rims Built for Drivers Who Expect More

At RRT Forged, we don’t build generic aftermarket car wheels. We engineer precision custom rims for drivers who understand the difference between marketing and metallurgy.

If you’re searching for forged wheels that improve performance, reduce weight, and transform the stance of your vehicle, here’s what actually matters.

What Makes RRT Forged Wheels Different

Every RRT wheel starts from 6061-T6 forged aluminum. Unlike cast automotive rims that are poured into molds, forged wheels are compressed under extreme pressure. The result is a denser grain structure, higher yield strength, and better elongation properties.

What this really means:

• Stronger load resistance
• Lower rotational mass
• Higher structural integrity under impact
• Better fatigue life over time

Compared to conventional auto rims or flow-formed alternatives, forged construction allows us to remove material where it isn’t needed while reinforcing critical load paths.

This is how you build lightweight wheels without compromising safety.

Engineered Customization, Not Cosmetic Options

RRT Forged specializes in fully tailored aftermarket car wheels. Every wheel is machined to order based on your exact fitment.

You control:

• Diameter: 17” to 21”
• Width: 8” to 12.5”
• Precise wheel offsets
• Bolt pattern and hub bore
• Finish options including Gloss Black, Polished Aluminum, Evo Grey, Illusion Red and custom powder coats

We do not mass-produce generic forged rims. Each set is engineered for your vehicle platform — BMW, Audi, Mercedes, Porsche, Tesla, McLaren and more.

Proper offset and load rating are calculated to maintain suspension geometry, brake clearance and steering response.

Why Forged Wheels Outperform Cast Automotive Rims

1. Structural Strength

Forged aluminum offers significantly higher yield strength than cast A356 alloy. That allows thinner spoke sections while maintaining rigidity.

2. Reduced Unsprung Weight

Lighter wheels improve:

• Acceleration response
• Braking performance
• Suspension compliance
• EV efficiency and range

Lower rotational mass directly improves how your car drives.

3. Heat Management

Dense forged material dissipates heat more effectively, reducing stress during aggressive driving.

4. Long-Term Value

Quality forged wheels maintain structural integrity and resale value better than standard aftermarket wheels.

Designed for Performance-Focused Drivers

Our Extreme Series wheels are built using advanced 5-axis CNC machining techniques, including:

• Deep side cuts for weight reduction
• Rear mounting face pocketing
• Lateral spoke undercuts
• Load path optimized geometry
• Webbed spoke-to-barrel transitions

Nothing is decorative. Every profile exists to serve a mechanical function.

Choosing the Right Custom Rims for Your Car

When selecting forged wheels, focus on function before appearance.

Diameter and Width

Larger diameters improve stance and brake clearance. Width must match tire selection and vehicle purpose.

Wheel Offsets

Offset directly impacts handling characteristics and fender fitment. Incorrect offsets can cause rubbing or compromised steering geometry.

Bolt Pattern and Hub Bore

Must match factory specifications for safety and vibration-free operation.

Load Rating

Critical for heavy vehicles, performance builds and track use.

If you’re unsure, provide your vehicle model and brake setup. We calculate proper specifications before machining begins.

Maintenance and Longevity

Forged wheels are built to last, but proper care matters.

• Clean with pH-neutral soap
• Avoid acidic wheel cleaners
• Inspect for curb damage
• Re-torque after installation
• Consider ceramic coating for easier maintenance

With correct maintenance, forged automotive rims can outlast multiple tire cycles without structural fatigue.

2026 and Beyond: Performance Without Compromise

As vehicle platforms evolve — especially EV and hybrid performance cars — reducing rotational mass becomes even more critical. Lightweight forged wheels are no longer optional for serious builds.

RRT Forged builds:

• Custom rims engineered for strength
• Lightweight wheels optimized for performance
• Aftermarket car wheels designed around real mechanical data

If you are investing in your vehicle, invest in components that actually improve how it drives.
