These TEIN Basis Z Miata Coilovers are the most popular kit we sell for the Miata NA and Miata NB. Gives your Miata a much nicer stance, has the ability to lower a good amount to clean up fender gap and offers much better handling and performance over the tired and worn OEM suspension. The price might be cheap, but TEIN coilovers have a great reputation for performance, quality and longevity!

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.

Reviews on this product
These coilovers are great
i have only had them for a little over 2 months now. My first impressions were they feel more comfortable than stock but once you start taking corners at a faster speed you can feel the difference right away. The spring rates that are stated arent the correct spring rates( according to tein.com) front: 392 lb/in or 7 kgf/mm rear: 336 lb/in or 6 kgf/mm the rear spring rates seamed a little to high for a front engine/rear wheel drive but after letting the suspension settle there is no oversteer or understeer when putting the car under load it feels neutral there is still some body roll but i eliminated that with a front eibach swaybar and stock rear sway bar the fixed dampening seems to be spot on with the spring rates. Some may say there a little on the soft side but for daily driving and canyon runs these are perfect. The price is amazing these are a great **** for your buck the quality is amazing and the performance is spot on.
Great coilovers for the price!
They ride really nice and gives the car a proper stance that it should have had to begin with. They do seem a bit soft but very comfortable for daily driving. Build quality is great, they looked great and were easy to install. Wish you could go a little bit lower, but I can't complain.
This is definitely one of my first stops when shopping around!
I wanted to replace the stock suspension with something a little better while burning as little of my play budget as I could. I chose these over the Racelands. Easy to install and adjust, gave the car a killer stance, rear now naturally has a bit of negative camber (-1.3 Deg) which is almost perfect for a road setup. Car sits on 15x7 Konig Heliums and 205/50 tires. I set the front height to 12.25" (hub to fender), rear at 12.75". Car rides perfectly, a bit stiffer than stock (no idea how old the Sachs Suspension was), but still ok as a DD. Car corners HARD, and almost completely flat. New Sways, links, and bushings are next. I'm very happy, allowing me to enjoy the car as I continue to build it and move to power. When the Teins get replaced with an Ohlins setup, I won't be upset at the $$ I spent on these as the interim. Lastly, the guys at Redline360 are fantastic. Killer customer service and great communication.
