Yonaka Motorsports is a grassroots performance part manufacturer since 2001, specializing mostly in Honda/Acura.  Today they have expanded their product line to meet the needs of Lexus, Mazda, Subaru, Mitsubishi, Toyota, Nissan, GM, and Ford.

Yonaka Motorsports Race coilovers for all 1996-2000 Honda Civics. 
This is a modified version of our popular Civic coilovers with significantly stiffer springs and a heavy duty dampener.

These coilovers are setup out of the box for FWD drag racing. The 18KG rear springs are incredibly stiff, designed to prevent rear "squat" on hard launch. For road racing, the lower perches would need to be swapped in order to run the 18kg springs in the front and 12kg springs in the rear for more neutral handling. Under NO CIRCUMSTANCES would these coilovers be suitable for use on a vehicle to be used on public roads or highways.
