TEIN Suspension Kits

Brief summary & key benefits

TEIN suspension kits help you strike the balance between daily comfort and spirited handling. Vehicle-specific tuning, accurate ride-height control and broad damping ranges improve cornering stability, braking attitude and steering feel. A sensible drop lowers the centre of gravity, reduces roll and pitch, yet keeps the car practical on imperfect roads.

Technical Basics

Kits pair matched steel springs with gas-charged dampers. The threaded body and adjuster collar let you set height precisely per axle. Coatings protect against corrosion, dust boots keep sliders clean. Street-biased lines often use twin-tube construction for supple low-speed control; sportier kits may use monotube designs for heat stability and crisp response. Some models offer combined bound/rebound adjustment, others split settings; upper mounts can be OE-style bushed or pillowball with camber plates.

Selected applications support EDFC electronic damping control, allowing in-cabin changes (where supported), which is handy when swapping quickly between city, highway and track use.

Selection Criteria

Use case — for daily and fast-road driving choose moderate rates and a wide damping window; for frequent track work consider stiffer springs and pillowball top mounts.

Axle loads / engine — pick the exact kit for your body/engine variant; incorrect axle load targets the wrong spring and damping window.

Height — aggressive drops cut bump travel and alignment range. Start near mid-range and fine-tune in small steps.

Alignment — always perform a full four-wheel alignment (camber/caster/toe) after installation and major height changes.

Wheels/tyres — large wheels and low profiles increase bottom-out risk; adapt ride height and check bump stops accordingly.

Installation & Maintenance

Have a qualified shop fit the kit. Replace worn top mounts, check dust boots/bump stops. Clean and lightly grease threads, torque all fasteners to spec, and preload rubber bushes at ride height. After a shakedown, re-torque and align. Periodically wash threads, refresh anti-corrosion spray and log baseline settings (height/damping). Investigate any knocking, oil traces or harsh pogo immediately.

FAQ

Q: How low can I go safely?
A: Stay within the manufacturer’s approved range to preserve travel and geometry.

Q: Is alignment mandatory?
A: Yes — lower ride heights alter geometry, so set camber/toe/caster properly.

Q: What baseline settings should I start with?
A: Begin near the mid-range height and the recommended damping baseline; refine to taste.

Q: Are noises in cold weather normal?
A: Slight NVH increases are common with firmer bushings; persistent knocking requires inspection.

Q: Is EDFC worth it?
A: If your kit supports it and you switch modes often, in-cabin damping control is very convenient.
