Prova WRX STI VAB Sports Spring

Sports suspension spring set set exclusively for each car. By using high-quality spring-specific steel and carefully post-treating it, you can use it with confidence without aging deterioration, so-called sagging or shrinkage, even after long-term use. In addition, a soundproof rubber is installed as standard equipment in the part where the winding pitch of the spring is narrow, reducing the grounding noise that tends to occur at low speeds.

By thoroughly conducting actual driving tests during development, we set the optimum rate that is excellent for matching with genuine dampers, and at the same time determine the amount of lowdown while ensuring sufficient stroke. You can enjoy excellent ride quality and sporty handling, and the looks of the vehicle will be tightened by moderately lowering the vehicle height.
