    Product Description

    STREET BASIS Z is strictly a ride height adjustable kit. This makes it a perfect setup for the daily driver looking for an increase in handling performance without compromising comfort for everyday use. For many of you considering a lowering spring + performance shock absorber combination, the STREET BASIS Z makes even more sense as we select appropriate spring rates and valve our dampers to match. No guesswork on the end-users part in trying to match one brand of springs to another brand of shock absorbers. The added height adjustment feature allows the end-user the ability to adjust ride height to their preference, something that lowering springs lack. Being that most vehicles are slightly unbalanced from left to right sides, that means you can easily adjust the ride height so that each corner is even from their opposing sides.

    TEIN coilovers are built from TEIN's direct knowledge of suspension products due to their extensive racing history.  TEIN Street Basis Z Coilovers are TEIN's entry level coilover that gives you all of the benefits of a high quality height adjustable coilover at an entry level price. 

    The TEIN Street Basis Z coilover is designed to provide the feeling of a sports suspension with an aggressive stance.  Developed to have a shortened shell case that provides optimum damper stroke at a low vehicle height allowing your car to have a good ride even when low.  Ride height is adjutable via the TEIN ZT coated threaded sleeve.

          Overall Great Coilovers

          I was hearing rumors about these coils claiming they don't go as low. Im currently on 20s and my car looks really dumped and slammed. The Fronts Do Go Lower Then The Back And I wish the back went an inch lower. If you are on 18's or 19's and you want that slammed look i would reconsider but if you just want to get rid of that nasty gap then these are for you. If you want to drive really low reconsider your decision. Overall, great performance no issues.


          Huge difference in ride quality

          I want to give you an update since we received the street Z basis coilovers for my son’s G35. We installed the rear struts and springs on Saturday. The installation was straight forward and made a huge difference in ride quality. On Sunday we tackled the front with help from a friend that has experience working on suspensions. With his help the job went quicker than the rear. The difference in ride quality is incredible. The car is still set up low but it rides as smooth as the original factory setup. My son is super happy with the new setup. Thanks for your help.
