My Tein Street Basic Coilover review
I have had my car for about 2 years now and I have always been kinda upset with the amount of body roll that stock nb's have out of the factory. I wanted to be able to take on/off ramps with more confidence and also get rid of some of the excessive wheel gap that the car had. I also wanted to be able to autocross on them occasionally, and be some what competitive. In the beginning of my research I was looking at ordering springs and shocks separately, but after looking at some different combinations, and getting some different opinions, I could not decide on a combination that would best fit my needs and price range. I began to think about the possibility of purchasing a coilover kit, but I didn't want to spend a ridiculous amount of money. I began to look at several coilovers in the high price range. I pretty much saw the Tein's and became locked on them almost immediately. I read the reviews of not only miata owners with the coilovers installed, but I also browsed the other popular car forums for other owner's opinions. Almost every review I read talked very highly of the coilover kit so I was fairly certain that that was the choice for me. I did some research as well on other competitive coilovers in the price range. The Megan EZ Streets were one of the first competitors I looked into, but after some searching I decided against them because some repetitively bad reviews I read about the build quality of the product as well as the coilover not being a typical miata used product. Another product that I looked into were the Tecna Coilovers from 949 Racing. For me the #1 reason I did not purchases these is because I did not have the patients to wait till October for the product to release then wait around for reviews to come out on the product. So I decided on ordering the Tein Street Basis from 949 racing and within a week they were sitting on my doorstep.
After staring at the coilovers for about 4 days, while they sat in my garage, I woke up on a Sunday morning and began the install. A few tools to have handy would be; a wide variety of regular and deep sockets, a breaker bar, socket extension, Alan Wrench set, Crescent Wrench, PB Blaster/WD40/Some sort of lubricant, and many many more, these are just some that are off the top of my head.
Overall the install was not to bad. My father and I began the installation and a friend of mine (another miata owner) came and helped out on the install later in the day. All 3 of us were your typical DIY mechanics. The rear suspension was very easy to assemble/reassemble and the removing of the shocks/springs were very simple. At first glance the instruction manual provided by Tein can be very hard to read and understand, but after the assembly of the first 2 coilovers it became a walk in the park.
Once the coilovers were installed in the rear I adjusted them to the standard ride height that was provided by Tein in the manual and moved on to the front. The front was a little more tricky than the rear. The disassemble of the front suspension was a little confusing at first because we could not get the spring and shock out by just removing the endlinks and lower control arm like we did in the rear.
SO, we figured out that the upper control arm need to be removed in order to remove the existing spring/shock which was a little bit of a pain because there is a bolt that is about 8 inches long that has to be removed/reinstalled. Other than that the installation of the front coilovers went smoothly...oh wait I forgot to mention that I dropped the LAST NUT that screwed onto the upper mount way down into the engine bay. So after a very long Easter egg hunt for the nut I went down to the Autozone and picked up another 15mm nut.
Without even driving the car yet I was so impressed. It defiantly gave the car the lower/sportscar look that every miata should have had. With the standard settings of ride height that Tein suggested, the car looked great while still retained full wheel rotation without body rub.
Now to the fun part, the driving. When I got behind the wheel of the car and began to drive it I had to look down a few times to make sure this was still my car. The car felt so much more nimble and agile than the previous stock setup. The real difference is felt in the handling and the stiffness of the suspension. I now can feel confident entering turns at high speeds because of the lack of body roll the coilovers provide. After taking it on and off a few exit ramps I knew that this was the product I was looking for.
- Here comes some of the stuff people don't want to hear. The setup IS stiff! I'm not going to lie, the spring rates are few stiff for a DD, but it is not unbearable. The roads I have to drive on daily are absolutely SUCK (Leave it to SC). The ride is bumpy and there is alot more road/car noise than there was before (my top tends to rattle a lot but with the top down its not big deal at all), but on good pavement the car feels absolutely fine. I just recently made a 240 mile (round trip) road trip with the suspension. The drive was mostly interstate travel (once again SC roads really really suck).
- My grandfather (65 years young) and I (17 years old) both embarked on this journey together. For me it was not to bad of a ride, but I am in my prime I guess you would say. As for my grandfather, he saw a little sore in the lower back, but that was mostly contributed to the all day standing that he was faced with (Wish I would have got more of his opinion, something I will work on getting within the next few days from him).
- Overall the ride is not to bad but it definitely favors those who don't mine a real sports's car'ish feel.
- Last week I went and had the car aligned which was the icing on top for me. After the car was properly aligned, the car wanted more and more around every turn, and it felt as if it was never satisfied no matter how fast I took a turn.
- First Autocross on the Coilovers
- OK, first autocross on the coilovers, and first autocross I had ever competed in. The car felt absolutely great, the course was basically a whole lot of slaloming which set up really good for me and the car. The car was a tad oversteer'y but that was expected/welcomed.
- For running an almost stock NB in STR, on crappy tires and stock wheels, and It being my first time auto rossing I felt as if Me/the Car did an OK job. I was about a 1.5 sec off the STR leader but only a .5 sec off second.
I am absolutely pleased with the Tein Street Basis Coilovers both aesthetically and performance wise. The install is generally pretty easy and a typical DIY mechanic could finish the job in a couple of hours. The manual is a little skimpy but with careful reading everyone should be fine. The ride is a little rough, but honestly not too bad for relatively short commutes. Even for the longer trips the ride is not too bad, but is ultimately dependent on the road conditions you are driving on. I would highly recomend this to anyone who is looking for better performance out of there miata or just simply needs to change out the existing spring/shocks.
I hope that someone, somewhere, maybe ever so slightly found this helpful. Feel free to leave me a comment or a question on something and I will do my best to give you an accurate answer. Thanks to anyone who read the whole thing.
