Why K7 Forged Racing Wheels Give Racers the Winning Edge

No matter how skilled a racing enthusiast is, he cannot defy the laws of physics. And when he’s on the track, the forces of nature show their prowess – the biggest of them are the friction between the wheels and the road and the centripetal force while cornering.  While on the road, be it for drag racing or track racing, your wheels are what help you tame these forces. This is why you need high-performance wheels for a high-stakes environment, especially racing. Forged wheels have become the gold standard for racers looking for the ultimate in performance and durability. In this blog, we’ll tell you why forged wheels are superior for racing.

Types of Performance Wheels

Performance wheels come in various types, each designed for specific purposes like lightweight performance, motorsport, track racing, or competitions. The main types include:

1. Cast Wheels

Cast wheels have the simplest manufacturing process where molten aluminum is poured into a mold. Once the metal cools and hardens, the wheel is removed from the mold and gets further machined.


  • Cast wheels are cheaper to make.
  • Simpler manufacturing allows for a variety of designs and sizes.


  • Cast wheels are heavier which reduces acceleration and handling.
  • The casting process creates micro-voids in the metal, creating weak spots.

2. Flow-Formed Wheels

Flow-forming or rotary forging, is a hybrid process where the cast wheel is placed on a machine that applies high pressure to stretch and compress it while it is spinning.


  • Improves strength by refining the grain structure of aluminum.
  • Results in a lighter wheel compared to traditional casting.


  • More expensive than cast wheels, but less costly than forged wheels.
  • Stronger than cast wheels, but do not match the durability of fully forged wheels.

3. Forged Wheels

Forged wheels involve heating a solid billet of aluminum and then pressing it into the shape of a wheel using immense pressure..


  • The forging process eliminates any porosity and creates a dense, uniform grain structure.
  • Significantly lighter than cast and flow-formed wheels​.
  • Can be custom-designed to precise specifications.


  • Usually the most expensive due to the complexity of the manufacturing process.
  • The forging process is more time-consuming, which means longer wait times for custom orders.

Why Forged Wheels Are Preferred in Racing

Strength and Durability

The high-pressure manufacturing process for forged wheels compresses the metal and removes any air pockets or porosity that can weaken the structure. 

This naturally improves the wheel’s strength and durability, making forged wheels exceptionally resilient against impacts and stresses that are a part of racing​.

Weight Reduction

In racing, reducing the unsprung weight is crucial. Upsrung weight is the weight of components that are not supported by the car’s suspension. This includes the wheels, tires, and brakes.

As the forging process uses less material, it reduces the weight of the rims without compromising strength. A typical forged racing wheel can weigh up to 25% less than a comparable cast wheel. This weight reduction gives you quicker acceleration and precise handling, which are critical in competitive racing​​.

Heat Dissipation

Heat dissipation in forged wheels is much better due to the dense and uniform grain structure. Cast wheels, on the other hand, have internal voids and irregularities that reduce heat flow​.

Better heat dissipation means better brake performance as it prevents overheating and brake fade. So, you’ll get consistent braking power throughout the race. It also improves the longevity of the brake components and the wheels themselves​.

Customization and Precision

With forged wheels, you can have custom dimensions, offsets, and intricate design features that are specific to a racing vehicle​. Custom wheel rims improve the aerodynamics and fitment of the wheels. Aerodynamic wheel designs reduce drag, which can improve top speeds and fuel efficiency. Precise fitment ensures that the wheels align perfectly with the car’s suspension geometry.
