If you've ever picked up an Enkei RPF1, you know—it’s stupid light. But have you ever wondered why this wheel is so much lighter than others in its class, especially given its strength and affordability?
Whether you're building a track car, drift missile, or a canyon carver, lightweight wheels matter. Less rotational mass means faster acceleration, shorter braking distances, better handling response, and a car that just feels more alive. And few wheels hit that sweet spot of performance, price, and weight like the Enkei RPF1.
What Makes the RPF1 So Light?
On paper, the Enkei RPF1 doesn't seem real. A 15x8 version weighs just under 13 lbs. The 18x8 variant clocks in at around 17–18 lbs. That’s lighter than many forged wheels—yet the RPF1 is technically a cast wheel.
But here’s the kicker: it’s not just any cast wheel. That’s where MAT Technology comes in.
What Is Enkei’s MAT (Most Advanced Technology) Process?
MAT stands for Most Advanced Technology, and it's Enkei’s proprietary process that blends the affordability of casting with the strength and weight savings of forging.
1. Flow Forming the Barrel
After the RPF1 is initially cast, Enkei uses a rotary-style spin forging technique on the barrel. This process stretches and compresses the metal, aligning the grain structure similarly to forged wheels. The result? A stronger barrel with thinner walls—meaning less weight without sacrificing structural integrity.
2. Strength Where It Matters
By strengthening the wheel in the barrel area, where the most rotational mass exists, Enkei reduces weight where it counts the most. That translates to quicker response on throttle, braking, and turning.
3. Increased Rigidity
The MAT process improves tensile strength by up to 30% compared to regular cast wheels. That allows Enkei to use less material in critical areas, helping shave off pounds while still withstanding the abuse of racing, drifting, or spirited driving.
4. Motorsport DNA
MAT was developed through Enkei’s deep involvement in Formula 1. The RPF1 shares real race engineering DNA, and every ounce of material serves a purpose. No fluff. No extra mass. Just pure function.
The RPF1: Lightweight, Strong, and Track-Proven
The RPF1 isn’t just a “light” wheel—it’s a purpose-built performance upgrade trusted by grassroots racers, time attack drivers, and drifters worldwide. It clears big brake kits. It dissipates heat through its pocketed lug design. And it looks timeless on everything from Miatas to Evos.
Best of all? The RPF1 is made in Japan, meaning you’re not dealing with heavy import tariffs or shipping delays. And because Enkei produces these in large volumes, there’s usually solid stock availability and fast turnaround times.
