Iris ONE.05 Competition Touring Car

- Iris ONE.05 Competition Touring Car Kit - Improvements -

Over the next few days, we'll be diving deep into the enhancements we've introduced with the new Iris ONE.05 touring car.

Let's kick things off with the heart and soul of every car: the chassis. The ONE.05 showcases several significant advancements. Firstly, the new chassis trims the front overhang by 10mm. The bumper now mounts onto a raised carbon fiber plate, enhancing handling both under braking and when navigating curbs.

But that's not all! The updated chassis plate has been engineered for optimized flex characteristics. To achieve this, certain holes at the front have either been removed or reduced in size. Conversely, we've introduced two new holes just behind the motor position. We've also incorporated a dedicated hole for more straightforward Ackermann adjustments right below the steering.

And last, but certainly not least, we've added holes for the chassis pin locators. These sync seamlessly with the new bulkheads, motor mount, and damper cases. Stay tuned, as we'll delve deeper into these features in our upcoming posts!

The motor mount of the ONE.05 has been enhanced in multiple ways. Not only did we incorporate chassis pin locators to improve flex, but we also managed to lighten the motor mount by 3 grams. Additionally, we've introduced a carbon fiber stiffener between the spur gear and the motor mount. This reduces spur gear movement, thereby improving the durability of the spur gear.

Following our discussion on the motor mount, let's shift our focus to the bulkheads of the ONE.05.
These now feature three chassis locators, with two of them designed in an elongated manner to ensure they can withstand even the hardest impacts. This design helps maintain the alignment of the bulkheads and, consequently, the suspension arms.
To enhance usability, we've also adjusted the position of the anti-roll bar, ensuring easier access for adjustments and maintenance.
Moreover, we've undertaken additional machining on the bulkheads, which has resulted in a weight reduction of 13% or 0.9g per piece. This translates to a total weight saving of 3.6g for the entire car.

The primary enhancement in the new shock housing of the ONE.05 is its weight reduction. We've successfully cut down the weight by an impressive 24% or 1.7g per case, resulting in a cumulative weight saving of 6.8g for the whole car. Additionally, we've incorporated chassis pin locators on the bottom of each case.

Another major update for the ONE.05 is the redesigned shock rockers. Now featuring a 2-part design, they're crafted from aluminum paired with a precision-machined carbon fiber component. This revamped design doesn't just look sleek but also profoundly influences the car's on-track behavior. It minimizes chassis roll and simultaneously elevates the ride height beneath the arm, providing greater clearance over curbs. Furthermore, there's no longer a need for the lower suspension arm shock mounts since they now attach directly to the arm via a new ball stud.

The upper suspension mount of the ONE.05 also underwent a significant update. In our pursuit to enhance overall grip, we increased the flex of this component. Concurrently, we achieved a weight reduction of 35%, translating to a savings of 1g for each mount.

Iris ONE Aluminium Spool and Differential Outdrives
These hard-coated aluminium differential and spool outdrives for the Iris ONE.05 and ONE.05 FWD cars have been developed for the 17.5T and 21.5T stock class. They provide a weight advantage of around 3 grams per pair compared to the steel parts and so improve the performance of your Iris ONE.

Features:

Ideal for stock class racing
Hard-coated for added resilience
Suitable for Iris ONE, ONE.05 and ONE.05 FWD models
Weight benefit of about 3g compared to standard steel outdrives

Another enhancement made for the ONE.05 pertains to the differential sealings. Building upon our previous update with the shock o-rings, we've also transitioned the differential o-rings to the same silicone type seals. For the main seal of the differential, we've moved away from a paper seal, opting instead for a specially designed rubber seal. This ensures the differential is fully sealed right out of the box. While the aluminum differential cover remains a worthwhile option, it's no longer essential for achieving a leak-proof seal—our new rubber seal takes care of that effectively.

The servo mount has also been updated in the new Iris ONE.05. First and foremost, we've incorporated a steering angle limiter into the servo mount. Additionally, we've expanded the space at the front of the servo area, allowing for greater compatibility with a wider variety of servos.
