Not only has rigidity been increased by using A7075, but the pivot height has been raised by 2mm compared to the standard part R300B/300H, providing more responsive steering and changing the camber change rate. To ensure clearance inside the wheel, the ball has been downsized from 8.5 to 8.0mm and the screw cap from 10 to 9mm and tilted by 10°. A specially prepared 8mm titanium ball is included to ensure proper steering angle. The main body is hard anodized.
New 0.8 module spur gear designed for high precision, high strength, and high durability. Gear specifications have been redesigned to provide uniform backlash for all tooth number combinations. The tooth width of the 2nd gear spur gear (R0409T56-T58) has been increased by approximately 12% to achieve even higher strength and durability. *Cannot be used in combination with conventional 0.8 module spur gears (R0247-60-62 and R0248-56-58) to prevent gear breakage. *Pinion gears for IF18-3 (R0384T18, R0384T19, R0385T23, R0385T24) must be used.
Stainless steel material offers supple flex characteristics while adding extra weight for improved stability on high grip surfaces. This option part promotes mild steering characteristics.
By installing this Front Carbon Wheel Plate on the front knuckle, turbulent air generated in the front wheels during driving is cleaned up offering more stable driving characteristics. The effect is especially noticeable on high-speed circuits.
An all new front one way set featuring larger one way bearings for improved durability. The timing of the drive transmission to the front tires has also been changed resulting in milder and more easy to drive characteristics. The overall weight has been reduced to 24g, 4g lighter than the original.
Machined from high quality A7075 aluminium material. IF18-2 knuckle upper and lower insert. Prevents misalignment during a crash and enhances steering response during cornering. This bushing is used for central alignment of the upper pivot (0mm kit standard zero offset).
When assembling these parts first remove the front knuckle upper. Place the offset bush into the knuckle upper from the outside. Then pass both M3x14mm slim head screws through the knuckle upper from the inside and tighten the 3mm nylon nut on the outside.
High-precision machined aluminum spring guide for improved steering response and rear traction. Hard coating is applied to ensure durability of the contact area with the spring and to maintain good condition for a long period of time.
Option part for IF18. This aluminum body mount spacer is to be used together with the optional 1 piece carbon mounting plate (R0198) Offers extra body post stability and is available in both silver and red.
Connects the brake mount L/R to the rear lower bulk, This part increases the rigidity of the rear area. It improves the rear grip.
