Hotchkis Stage-1 Kit for the BMW 3 Series cars consists of two products engineered to work together for everyday road and track day handling. All Stage-1 Kits include Hotchkis Coils (#19824), along with bump stops (front and rear) and a Sport Tubular Sway Bar Kit (#22825). The Sport coils will lower the E46 approx. 19mm front, 9.5mm rear while retaining excellent ride quality. Replacement bump stops are also included for additional extra travel needed with the lower stance. To compliment the Sport coils, the Stage-1 Kit includes the Sport Sway Bar Kit consisting of adjustable, tubular front and rear sway bars, polyurethane bushings, bushing brackets and zerk fittings for easy lubrication. Hotchkis' unique rear sway bar bushing bracket allows the use of zerk fittings and also adds strength to the subframe. The Stage-1 Kit is perfect for those who enjoy canyon-carving and occasional track day events.
