Product Description

The Tein Flex Z Coilover Kit (Part # VSA02-C1SA1-C) is a fully-featured suspension upgrade designed specifically for the 2002-2006 Acura RSX (DC5) 2.0L I4 FWD platform. This kit offers substantial improvements in handling, ride control, and stance by providing a full-length ride height adjustment, 16-level damping force control, and race-inspired construction - all while maintaining street-friendly compliance.

Designed for enthusiasts who want to lower their RSX by approximately 1.8 in while preserving daily driving comfort, the kit features twin-tube dampers with No-Sag springs and pillow-ball mounts. Drivers will notice reduced body roll, improved turn-in, better cornering stability and a tighter ride without sacrificing refinement on the road. Installation is straightforward but should be done with proper alignment after ride height adjustment and camber tuning.

Please note: because the camber-adjustable range is limited on the RSX platform, adjust camber within the acceptable toe-angle range to avoid alignment issues. Also, the front LH lower mount uses left-hand threads, so be sure to tighten in the correct direction to avoid installation errors. Ride height out of the recommended range may cause clearance or warranty issues.
