Features & Product Details

If you're in the market for an affordable set of coilovers that won't break the bank, then the Tein Street Basis Z coilovers would make for a great option. These are ride height adjustable coilovers that will improve handling, performance, and the stance of your vehicle. These coilovers feature a sealed structure, in which Tein designed the body to have a narrow shell pipe to allow oil and gas to be injected, Then the body is then completely sealed.

Ride height can be adjusted by moving the lower spring seat either up, or down, making level adjustment simple and efficient. Additionally, the Street Basis Z coilovers utilize a twin-tube system which attains a longer stroke with a smaller repulsive force which provides better ride comfort. This design makes the coilover suitable for all kinds of road conditions which will make for smoother rides at lower speeds, while having more stability on higher speed levels. 

With the Street Basis Z coilovers, users will re-use their OE upper mounts to complete installation, and these coilovers will come supplied with an optimal dust boot, no-sag springs, and the coilovers will come powder-coated in Tein's flagship green powder-coat finish for protection against corrosion.

I have ran these on both my Wrx's now. On my 08 I had no issues with them whatsoever. On my 14 though, I have found that you will need to purchase camber adjustable top hats in order to adjust the alignment properly. Not a bad ride though for the price.

I reviewed these coilovers when I first purchased them a little over a year ago. I figured I'd go back and update that review, however I can't, so RSD, feel free to delete my original review. These coilovers have held up great! My WRX is my daily driver and I also take it on road trips. This includes going to to Arizona last year from Northern California. They feel just as great as the day I put them in! And have held up phenomenally! As I mentioned in my previous review, they are a little stiffer than stock, but it's totally tolerable. These are a very reasonable priced coilover set for a daily driver. Not to mention the your car is equipped with Tein! Ordinarily the Tein name can cost you $1000+, and here is the name at half the price! Just gotta reuse the tophat of your original strut. So having the mechanical experience is recommended for putting them in. Also another point I should make which is very important, there are no clunks or rattles after the install and still none a year later! I've played with the ride height a little and found my comfort zone where I don't bottom out, I have the lowered look, and the ride is excellent! I'm very happy with these coilovers and I would recommend them to anyone in an instant! 5/5 stars!

These are really good for the low price. Increased handling and definitely dropped the car 3 inches with room to go.

Best bang for the buck by far 2 years ago
5out of 5stars

I will start off by saying this is my third wrx (2012) I've also previous owned a 2002 and also a 2007. With these three cars I've had all with stock suspension the 02 with racelands, the 07 with toteiko d spec struts rce springs and also with swift springs. I can honestly say I personally loved feeling and handling the best with the spring and struts but I just didn't get the desired drop that I had with my 02 on the racelands. Personally I did not like the feeling of the racelands or the ride quality. Plus I ran into problems with them simply because they are garbage. I bought these because they are cheap I can run them for a year or so and just to do some test fitment with my desired drop for awhile. I was worried I would run into problems that I had with the racelands. This is also the first coilover I have ever had that had to replace the top hats I re-used the stock ones which had 82k on them. I can honestly say that these coils are incredible for the price. I was worried about them being a little to stiff for me. (Especially because I gave whiteline swaybars.) They aren't at all in fact I didn't slam them because they do seem more on the softer side compared to most coilovers I have ever dealt with. You will rub just barley with these if you slam them on a 2011-2014 wrx. Over ride quality is not as good as springs and struts but is pretty close. I am very impressed and I would make this purchase again. The max drop height is 2.9 I went with front 2.4 rear 2.5

The price had me skeptical at first... I debated just shelling out the additional $400 for the Flex Z that way I don't have to deal with swapping over the top strut mount. But I have access to a good spring compressor so I figured I'd give them a shot. Plus Rallysportdirect offers 30 days satisfaction guaranteed. I was very impressed. Installation was easy enough due to experience and access to a shop. It took me about 3.5hrs to put them in. Once installed, I was able to get my height adjusted which was is very simple. I lowered the ride height by about an inch and a half. Then the test drive... which is where these coilovers really impressed me. I couldn't believe the comfortability of these coilovers. I little stiffer than the factory struts, but really not bad. Going around some corners felt great! No noise or anything from them either. I couldn't believe I just installed Tein coilovers for about $500! These coilovers are a bargain! I highly recommend them. I couldn't be more satisfied.

    How do I make them stiffer ???? When I’m on the road they are just to bouncy, do I just lower them all the way to go stiffer ??

      A:  Most likely yes. I have wrx struts on my 2009 2.5i. So fitment should be fine.
