各車専用に設定したスポーツ・スプリングセットです。
高品質のスプリング専用鋼材を使用し、さらに入念に後処理を行うことで、長期間使用しても経年劣化、いわゆるへたりや縮みが発生せず安心して使用できます。
またスプリングの巻きピッチの狭い部分には、防音ラバーを標準装備、低速時に発生し易い接地音を低減させています。
開発に当たり徹底的に実走行テストを行うことで、純正ダンパーとのマッチングに優れた最適なレートを設定、同時に充分なストロークを確保しながらローダウン量を決めています。優れた乗り心地とスポーティなハンドリングを味わう事ができ、適度な車高ダウンにより車両のルックスを引き締めます。

Prova sport lowering springs are specifically designed for each vehicle to provide exceptional performance and appearance. There is no need to compromise ride quality to lower your vehicle, as careful consideration has been taken to make these springs a truly complete solution.
High quality spring steel is employed along with precision after treatments to produce a spring that can be used without fear of sagging or shrinking. Rubber isolators are included as standard to reduce the possibility of noise from the springs at low speeds.
An intensive development process along with testing on the vehicle led to the creation of a spring that gives excellent results while retaining compatibility with OEM dampers. While the vehicle is lowered to improve handling and appearance, adequate suspension stroke is retained to preserve streetable ride quality. With these springs it is possible to obtain attractive looks, sporty handling, and complacent ride quality all at the same time.
Springs are specific to chassis type (sedan/wagon) and trim level.
