- Adjustable Height: The height is adjustable for 1-4 inches(Notice: The coilovers kit will "Lower your car" and does not keep to the original ride height.), allowing you to have a more aggressive stance, allowing you to have a more aggressive stance. This design helps eliminate turning noise and also improves steering feel and response. In addition, we have adopted a deep groove ball-bearing structure to help eliminate cornering noise and also improve steering feel and response.

Twin-tube Structure: Compared to mono-tube construction, the twin-tube has a longer stroke and higher height adjustability, and they will give you a more comfortable riding experience by reducing the pressure on the joints and also minimizing friction, and ensuring sufficient travel with less effort.
- Functionality: Enhance steering performance and prevent cornering understeer and oversteer. Reduce cornering roll and improve braking performance, leading to shorter braking distances and increased driving safety. The coilover struts are easy to install with the proper tools

FAQ
Q1: What vehicle models are compatible with this Flashark coilover kit?
A1: These completely assembled coilover shock absorbers struts are engineered as a direct fit for the 1988-1994 Nissan S13 240SX. They replace your worn-out factory suspension without any modifications needed for unmodified vehicles.
Q2: How much drop can I get with these 1988-1994 Nissan S13 240SX coilovers?
A2: This Flashark adjustable suspension kit allows you to lower your S13's ride height by 1 to 4 inches. Dropping the car lowers the center of gravity, which heavily reduces body roll and gives your 240SX a highly aggressive stance for drift or street applications.
Q3: What are the specific spring rates for this Nissan S13 240SX suspension kit?
A3: The front spring rate is 8 kg/mm (448 lbs/in) and the rear spring rate is 7 kg/mm (392 lbs/in), paired with a 7-10 mm spring preload. This exact setup provides optimal stiffness to enhance stability and grip in sharp corners.
Q4: Do these S13 adjustable coilovers include camber plates?
A4: Yes, the front strut assemblies feature premium pillow ball top mounts with integrated camber plates. This allows you to easily dial in your front wheel alignment, which is critical for track use and drifting. The rear shocks use standard rubber top mounts to reduce cabin noise.
Q5: Is damping adjustable on these S13 coilover shock absorbers?
A5: No, this specific kit features fixed damping. However, the damping is expertly pre-tuned by Flashark to perfectly match the 8k/7k spring rates, delivering an excellent balance of high-performance cornering response and everyday driving comfort.
Q6: What is the benefit of the twin-tube structure used in these coilovers?
A6: Compared to a mono-tube design, our twin-tube shock absorbers provide a longer suspension stroke and superior height adjustability. This design significantly reduces joint pressure and internal friction, resulting in a more comfortable ride on standard roads.
Q7: Does adjusting the ride height compress the suspension springs?
A7: Not at all. With our independent height adjustability design, you alter the ride height by rotating the lower shock body mount. This ensures you maintain full suspension travel and shock stroke even if you drop your Nissan S13 the maximum 4 inches.
Q8: Are there any extra parts required to install this 240SX coilover set?
A8: This is a complete, ready-to-install 4-piece package. It includes 2 front coilovers, 2 rear coilovers, and 2 stainless steel spanner wrenches to adjust the lock collars. However, we strictly recommend a professional alignment after installation.
Q9: How do these coilovers solve cornering noise and steering issues?
A9: Upgrading to these Flashark coilovers eliminates sloppy steering feel and cornering understeer. We utilize a deep groove ball-bearing structure within the top mount assembly to actively eliminate cornering noise and provide crisp, immediate steering feedback.
Q10: What kind of warranty covers these 1988-1994 Nissan S13 coilovers?
A10: Flashark firmly stands behind the durability and performance of our auto parts. This 4PCS coilover kit includes a comprehensive 2-year warranty against any manufacturing defects, ensuring your investment is protected whether on the street or the track.
