K-Tuned K2 Pro-Circuit 2-Way Coilovers 12-13 Honda Civic Si / 12-15 Base Honda Civic (9th Gen) - 14K front and 12K rear springs (w/ DS1 Valve)

Item SKU: KTD-F22-FG4-F14K/R12K-DS1

K-Tuned K2 Pro-Circuit 2-Way coilovers for the 2012-2013 Honda Civic Si and 2012-2015 base Honda Civic, 9th gen chassis. This set comes with 14K front springs, rated at 785 lb/in, 12K rear springs at 672 lb/in, and K-Tuned's DS1 valve setup.

• Spring rates: 14K front and 12K rear. These are the recommended rates supplied with this SKU for a track-focused Civic setup.
• DS1 valve: Included on this kit. K-Tuned offers the DS1 damper-valve option for cars that are driven to the track, so you're not starting with a circuit-only valve setup for every mile.
• Adjustment: Remote reservoirs and separate rebound adjustment let you make setup changes without treating ride height as the only tuning tool. Ride height is adjustable as well.
• Mounting: The Pro-Circuit family uses pillow-ball upper mounts. McPherson-strut applications use adjustable upper camber plates, which is useful when you're setting alignment after changing height.
• Damper hardware: Heat-treated steel pistons, needle valves, proprietary damper oil, and high-temperature double seals are part of the Pro-Circuit design. Springs sit on adjustable aluminum perches for preload and travel adjustment.
• Finish protection: K-Tuned uses powder coating, electroplating, and anodizing across the exterior components to help the parts hold up around normal suspension grime and track use.

This stuff is aimed at drivers who are actually working through spring rate, damping, ride height, and alignment rather than just lowering the car. The remote reservoirs and separate rebound adjustment give you room to dial in the chassis, while the included DS1 valves make sense for a 9th gen Civic that still gets driven to and from the track. No more being stuck with one fixed damper setting when the rest of the setup changes.
