The latest sedan modified by a group of professionals

Prova leads the Subaru customization scene. As a pioneer, they have customized many Subaru vehicles. Prova’s latest work is the WRX S4.

A lightweight aero part was adopted and wrapped to enhance its presence

The body was wrapped in deep matte red. The body side panels are now the same color as the body but with a cool finish. The hood, roof, side steps, and trunk were blacked out. The two-tone matte red and black has a racy look.

Varis’ ARISING-1 consists of a front spoiler, side skirts, rear diffuser, side splitter fins, cooling hood, lightweight trunk lid, and GT wing. Except for the rear diffuser, the rest of the parts are made using Varis’ proprietary CARBON+ manufacturing process, which reduces weight and increases rigidity.

Improved performance and handling

The engine compartment features a large-capacity aluminum intercooler. Intake efficiency has been improved with a carbon air induction box, and the exhaust is smoother with a Fujitsubo’s single muffler.

For suspension, Prova’s original Ohlins DFV ride-height adjustment kits were installed. The front brakes were also replaced with the Prova’s original 4-pot calipers.

A pair of Ray’s Volk Racing NE24 (9.5J x 19 +45) and Bridgestone’s Potenza RE71S (245/35R19) tires were fitted. Two Recaro Sportster seats have been fitted. The car is finished not only as a sports sedan, but also as an adult sedan.
