Product Code


This is the new "Z" line, manufactured in Tein's new China plant (which is owned and run by Tein). We have dyno tested it and it's identical in performance to the old Street Advance, which is great news. The only slight differences are in the "Z" coilover's favor, where the rear shock at full stiff is actually slightly stiff than the old Street Advance kit. But front and rear at full soft is IDENTICAL! Spring rates on the "Z" test almost identical as well. THIS IS A GREAT VALUE!!!! I think these "Z" coilovers are a huge new product in the market for what they are for the money. Absolutely amazing value.


Great coilover for street and track/autocross. A little stiffer springs than the ST Coilovers but not as stiff as the BC Racing. This has great adjustable shocks too, like the BC, except the BC is a monotube and these are twin-tube (like Konis) so they have a bit more comfy feel on the street.

So, if you like the idea of the ST coilover, but you want a touch more spring rate and adjustable shocks but you don't want go with a full coilover like the BC (with camber plates), this is your kit! :) The fact that this retains the stock upper front strut bearing and mount is one reason it is more street worthy.

Spring rates are listed in Tein documentation as 336/448, but we dyno'd the springs at 330/410... so the rear springs seemed to be a little bit softer than advertised... not a bad thing frankly.... we tested the Street Advance on our own car drove and it handle exceptionally well but was still decent as a true daily driver. I would highly recommend this to anyone wanting adjustable shocks and a medium-stiff but very street-able spring rate. Very Koni-like with springs that are more or less a bulls-eye on where we think they ought to be for a fun but decently comfy street car. Note that the shock adjustment is quite progressive... meaning out of 28 click, the first 14 don't do too much. But once you get to 21, you are about 50% of the way to full stiff. 25 clicks is about 75%. Then 28 clicks is full stiff.... so you see, most of the damping adjustment happens above 14 clicks.

Front Lowering: up to -1.6"
Rear Lowering: up to -1.6"

The Tein Street Basis is the exact same kit as the Street Advance, except the Advance has adjustable shocks.

5 of 5 Huge Upgrade from Just Lowering Springs July 16, 2019
Reviewer: Daniel Siebert from FL United States  
I gave Chris what my intended usage for my car and expectations were and he suggested these coilovers for me. I couldn't be happier. The combination of the new bumpstops, top hats, coils, springs, and dampers have my car feeling completely new. The modest drop of 1.6 in the front and 1.4 in the rear is perfect for a DD that will be going over speed bumps and potholes from time to time and doesn't make it feel like my car will break at any moment. Wonderful! I couldn't be happier.

5 star forsure. I will start off by saying stiff even above 8clicks is pretty damn stiff for street driving. I set to 10 for most street driving in LA. I had to get several alignments because Honda isn't used to doing rear camber alignments on fa5 or any car for that matter. So I had to show the tech what to do which must have been embarrassing. But other than that you will need a camber kit with these if you go lower than highest. Spring rate is okay for street driving but great for aggressive driving "Spirited" driving. I did not slam my car because I'm looking for the performance side of these coilovers. So I found out that best ride quality is about one inch drop rear 1.5 front. Thanks again redshift you guys kick ass.

5 of 5 Can't Beat Adjustable Dampening AND Ride Height February 5, 2016
Reviewer: Sargon Odah from Oakland, CA United States  
Great product! This is my second Tein coilovers kit, first on this 2009 Civic Si Sedan - my first set was on a 1999 Civic Si Coupe. This is exactly what I am always wanting in a coilovers setup, adjustable dampening for track and daily driving, adjustable ride height to keep a clean and customized ride profile. I elected to go with the HardRace Adjustable Rear Camber Arm, as the stock Honda parts are only adjustable in the front - I'm also using a HardRace Front Upper Control Arm set and a Cusco Front Sway Bar for added rigidity, Rear Sway Bar is still OEM. This is to get a scope of what I'm using the Tein's for.

So far, I've been riding them for about a month with dampening set to 8, I'll be adjusting to lower numbers after the springs have settled in, but so far the ride is stiff when necessary and not bouncy (unless the road dips). Great setup for under $1000!
