TEIN Street Basis Z Coilover Suspension

The TEIN Street Basis Z coilover suspension is a height-adjustable coilover kit (also called a coilover lowering kit) from TEIN. It is TEIN's entry-level coilover. It is built for drivers who want better handling and a lower, more aggressive stance without giving up everyday comfort. TEIN builds it in Japan, and it draws on the company's racing suspension experience.

Key Features:

• Twin-tube damper design: The twin-tube damper gives a longer stroke and smooths out bumps while staying stable at speed.
• Sealed damper structure: A fully sealed damper keeps production efficient, so the kit costs less without a drop in ride quality.
• Ride height adjustment: The ZT-coated threaded sleeve and spring seat let you set ride height to your preference. You can also level each corner.
• Preset damping: TEIN matches the spring rates and damper valving, so you don't have to pair springs and shocks yourself.
• Durable construction: The kit has steel construction, a powder-coated damper body, and a non-welded ZT-coated adjustment tube. It also has a 1-piece aluminum spring seat with a Delrin thrust washer.
• No-sag springs: TEIN's no-sag springs help the kit hold its ride height over time.
• Shortened shell case: The shorter case keeps damper stroke available at lowered ride heights.

The Street Basis Z is a good choice for daily driving and spirited street driving. It is a more capable alternative to a lowering spring and shock combination.
