Real-world performance and comfort

The two-tube architecture keeps gas pressure low to reduce stiction, so the shocks move freely over broken tarmac and potholes. The result is a supple low-speed ride and excellent stability at speed. The finely stepped adjusters, using Tein’s advanced needle valve, let you dial in the exact feel you want, whether you prefer a compliant daily setup or a firmer, more controlled setting for spirited driving or track sessions.

What you get

• Front and rear adjustable shock absorbers
• Matched coil springs
• Upper mounts
• Ride-height adjustment tools and documentation

Our experience

We have fitted and run this kit on customer cars and feedback has been consistently positive. Owners love the improved turn-in, reduced roll and the way the chassis stays composed on uneven surfaces, all while maintaining day-to-day comfort. It is a genuine step up from stock suspension and a smarter choice than basic lowering springs when you want adjustable control and quality.
