Tein Street Basis Z Coilover Kit 2002-2007 WRX / 2004 STI
If you're in the market for an affordable set of coilovers that won't break the bank, then the Tein Street Basis Z coilovers would make for a great option. These are ride height adjustable coilovers that will improve handling, performance, and the stance of your vehicle. These coilovers feature a sealed structure, in which Tein designed the body to have a narrow shell pipe to allow oil and gas to be injected, then the body is then completely sealed.
Ride height can be adjusted by moving the lower spring seat either up, or down, making level adjustment simple and efficient. Additionally, the Street Basis Z coilovers utilize a twin-tube system that attains a longer stroke with a smaller repulsive force which provides better ride comfort. This design makes the coilover suitable for all kinds of road conditions which will make for smoother rides at lower speeds while having more stability on higher speed levels.
With the Street Basis Z coilovers, users will re-use their OE upper mounts to complete installation, and these coilovers will come supplied with an optimal dust boot, no-sag springs, and the coilovers will come powder-coated in Tein's flagship green powder-coat finish for protection against corrosion.
