There are light rims that are produced by Enkei.
And then there are even lighter and stronger wheels made specifically for racing and competitions. But also made by Enkei.
The RS05RR is one of Enkei’s three Racing Revolution wheels.
The lightweight RS05RR is designed to look incredible while retaining Enkei’s racing spirit & functionality.
There are only two sizes available, 18x8.5 and 18x11.
The RS05RR is constructed by Enkei’s much more racing focused MAT DURA technology.
As we all know, the Most Advanced Technology combines one-piece cast wheel technology with a rim forming technology called spinning process. Using this technique of casting and rim forming is critical to improving the material property and strength of the wheels. Rim-Rolled technology shapes the rim to improve material elongation without sacrificing the wheels’ hardness.
This hybrid process of casting and forging gives wheel high material strength while keeping manufacturing costs less than forged wheels.
But the MAT DURA process even takes it a step further by making the wheel stronger without sacrificing stiffness.
Also like all of Enkei’s wheels, the RS05RR is engineered to pass rigorous testing. Enkei established their own test standard called “Spec-E,” which is tougher than JWL requirements. Enkei’s Spec-E test setting requires a higher drop point in the impact test and 20% more cycles for the rotary bending fatigue and dynamic radial fatigue tests than JWL standards. The Spec-E represents Enkei’s confidence in its technology and quality.
