Features & Product Details

The Tein Street Basis is one of the best cost-effective and quality set of coilovers on the market. This is a great suspension system for those who want something more aggressive than lowering springs. The Street Basis coilovers supersede Tein's Basic coilover design made with improvements in design and performance. These coilovers feature steel construction with twin tube internal components. These components include a larger piston diameter for the front and rear struts. 

These are height adjustable for those of you who want to improve the center of gravity in their vehicle, but to also provide the vehicle with a more pronounced look especially if you are equipped with a more aggressive wheel. These coilovers will come with 1-piece aluminum springs and they will come finished in Tein's flagship green color for extra protection against rust and corrosion. 

With the Tein Street Basis Coilovers, you will be using your factory top hats to complete the installation.

Great Kit to Replace Worn & Old Dampers 3 years ago
5out of 5stars
Replaced worn dampers on my STI that appeared to be original and the vehicle has 105k on the odometer. These do not come with strut mounts or top hats so you'll have to purchase them separately. I used KYB units and they bolted up with no problems. Adjusted the ride height by counting the visible splines between each lock nut. The car rides SO much better. It's firm and controlled. Not overly bouncy like cheap coil over systems. Body roll is noticeably reduced also. Overall a great package for a direct replacement of the O.E dampers if you're looking for something on the daily driver side.

We put these on my wife’s STi and they are loads better than stock! They’re stiff but not jostling. The car sits at a good height too. Well worth the money.

Bought as a stock shock replacement. 5 years ago
5out of 5stars
Car needed shocks(70k miles), so I decided to give these a try. Have probably 3k miles on them so far. Nice that they are adjustable, but wish they were about 1/2'' taller for ride height. I have them setting about 85% maxed out and leaves about 3/8'' gap above the wheels. About the same as the Tannabe lowering springs I was using before. Ride is little stiffer then stock but handles much better. Does well in turns and at faster paces and keeps everything composed. I would recommend these to anyone running lowering springs and are in need of new shocks. Kinda wish I went ahead and bought the full kit that came with adjustable top hats, but money was tight and these have been great so far. Current camber is pretty much 0 on the front, would recommend some new camber bolts with a little extra adjustment. I installed these in the garage following the instructions in the box over the weekend. Removing the top hats and installing is more time consuming then difficult. If you using Kartboy Endlinks, plan on buying about 4 of the replacement bolt kits. I snapped the lower bolt on each side of the rear trying to remove them. Decided to replace the worn out ones in the front as well. Quality seems good, see how they handle a the winter.
