Tein Street Advance Z Coilovers for your 2007-2012 Nissan Altima sedan and coupe.

The Street Advance Z damper is the damping adjustable version of TEIN's Street Basis Z coilover. Developed to provide a sporty ride feeling and aggressive stance, along with wide-range damping force adjustment using their new Advance Needle technology, giving the driver a much more noticeable feel in damping force change. The shortened shell case design provides optimum damper stroke at lower than standard vehicle ride height. Vehicle ride height is adjustable via the ZT coated threaded sleeve. Updated internal components and external coatings increase durability and product life. Street Advance dampers are great for daily driving and spirited driving for all types of drivers. 

16-Way Damping Force Adjustment

Damper includes 16-way damping force adjustment for both front and rear coilovers. Compression and rebound is adjusted simultaneously for ease of adjustment. Adjustment is made externally via a Click Assembly, and made internally via a needle valve which allows or restricts oil flow. Damping force can be changed to tune ride feel (comfort/performance level), and/or used to adjust handling characteristics (neutral, over-steer, under-steer, etc).

Full Length Adjustable

Vehicle ride height and spring pre-load can be adjusted independently. Ride height is adjustable in two ways:

1. Adjustable Shock Length:
   • The lower mounting bracket can be adjusted, thus changing the overall length of the shock, and therefore altering the vehicle's ride height. This also allows the user to determine suspension travel and droop.
2. Adjustable Spring Seat:
   • The adjustable spring seat allows for independent adjustment of spring pre-load without affecting vehicle ride height.

Aluminum spring seats are utilized to reduce ceasing of spring seat to threaded body, and for improved durability.

Twin Tube Design

A Twin Tube internal design is utilized for increased piston stroke for improved handling and comfort during street use. Another major feature of the Twin Tube design is that is more durable in the case of damage to the actual damper body.
