Overview

MONO RACING for your 2015-2024 Subaru WRX STI AWD (VAF) is developed to satisfy the drivers who frequently take their cars for a spin at the race tracks. Based on the settings of the high-end model SUPER RACING and on a wealth of data gained through participation in various motorsports, spring rates and damping force for MONO RACING are determined to be most suitable for sports driving.

For front strut suspensions, MONO RACING includes the camber and caster angle adjustable pillow ball upper mounts evolved from SUPER RACING upper mounts. Many upper mounts provide camber adjustment feature, but MONO RACING upper mounts are also caster adjustable. Camber angle can be adjusted steplessly while caster angle adjustment is available in 4 steps and both can be adjusted individually.

Lower brackets on strut type suspensions come with camber angle adjustment feature. Camber angle can be adjusted by rotating the eccentric collar 180°. This feature can enable camber angle adjustment, even if it can not be adjusted with the upper mounts. Both adjustments at the upper mounts, if applicable, and the lower brackets combined allows for total camber angle adjustment to meet various needs and preferences.

Mono tube structure of MONO RACING completely separates the oil chamber and the gas chamber and hence aeration does not occur. This enables stable generation of linear damping force, reacting to the finest changes in road surfaces, even when running aggressively and repeatedly on circuits. With this, superior-quality MONO RACING offers capability for the most delicate control of the vehicle and for the deepest level of communication with the roads.

Use of specially-designed urethane bump rubbers effectively reduces the bump impact, to maintain the comfortable ride even when going over bumps/gaps and to protect dampers from bottoming out. (The image shown is for wishbone / multi-link types. Some models use OE bump rubbers.)

MONO RACING uses "ADVANCE M.S.V." for damping force adjustment feature. "ADVANCE M.S.V." combines "M.S.V." mechanism to finely control damping force in micro speed range with "ADVANCE Needle" to widen the damping force adjustable range, for superior steering response and traction performance, fully utilizing the damping force adjustable range.
