Tein Street Flex Review and Short Video!

[three3y3wrbbrz]

Supprised no one has asked...but scince i just recieved my set of street flexes.....I am very curious to know what set up specs were used. Preload, ride height and alighnment also did you adjust the damping force throughout your road tests and if so what was the best setting, and how noticeable is the damping effect per click.

thanks

Unfortunately I do not have a ton of data for you, but will do my best

Preload was not touched out of the box, but we did measure per the tein manual to make sure everything was spot on, but I don't have the exact specs for that at the moment.
For the ride height, the front is almost maxed out, we might have an extra 2 full turns to go down, but lets just call it maxed out On the rear we have an extra 10 turns to go. I can grab the exact center bore to fender height if needed.
For the alignment, we are running -1.2 up front and roughly -2.5 in the rear. I say roughly as we had it dialed in, and was close to rubbing, so I had them add a bit more negative camber in the rear to prevent rubbing.
I did mess around with the damping, but was not able to get a proper performance review as the test was done during the winter and using summer only tires, so I was not comfortable pushing the car. However I can comment on the overall feel of the coilovers, and you can feel a difference for sure. I ended up leaving ours 3 clicks from full soft. I will be playing with this more as the weather warms up so I should be able to give a more indepth review in regards to the damping adjustment.

I will give you guys an update once I am able to play around with it more
Hope this helps.
Thanks,
Rick

Thanks. Any info helps.

i guess my biggest concern is maintaining the ballance front and rear spring rates like stock being that the teins are 7k front and back how do you adjust the coilovers to maintain that stock ratio at higher spring rate?
is it a combination of preload and damping or can you dial in more damping force in the rear to make the spring rate stiffer in the rear.

do you have the same damping force on all 4 coils?
also does the ride height being lower in the front make the ballance for front and rear spring rates?

You said maxed out front drop and ten clicks rear. What is the mm measurement of the drop? And lastly what are wheel tire measurements?

thanks for the reply and the info

Cant wait to hear what your summer time tests results and review produce

In regards to maintaining the balance, I would adjust the damping to bring the car back to where you like it set up. You can adjust the pre-load but really this is only recommended if you can do a corner balance at the same time, which really would be ideal if you really want to get the most out of the suspension.

Yes, our damping right now is set at the same on all 4 corners. I am positive I will adjust it to a different rate, perhaps a bit stiffer on the rear as the car does generally want to push with the setup right now. But I will wait until warmer temps so we can get the tires up to temp and see how it does then. I also might mess with the adjustable Whiteline swaybar to get the car where I want it as well.

We only used the lower perch for the height adjustment which is independent of the spring pre-load adjustment, so our pre-load was not adjusted. I will have to measure to give you the actual numbers on that, would you like me to measure on the coilover itself or would you like me to measure from the center of the wheel up to the fender?

Our wheel and tire spec are:
Wheels - Work CR KAI Ultimates
-18x9.5 +38 Rear
-18x8.5 +47 Front
Tires - Bridgestone Potenza RE-11
-245/40/18 Rear
-235/40/18 Front


Thanks again!

Ok good info...
When you say corner balance... after adjusting preload..what exactly are you reffering to..i apologise if the ? Sounds dumb just tryin to learn as much as possible before i install.

as far as the height messurement im looking to compare coilover ride height from stock height ...like how many mm lower than stock is the set up..so i guess hub to fender would give me something to compare...by any chance do you know what the stock measurement would be from hub to fender?

any reason you chose to max the front as opossed to even drop front and back?

thanks

Sorry, I should have been more clear. With the pre-load, I would not mess with that unless you have a professional to help you out, as it does get pretty in depth. To maintain the balance really you will be adjusting the ride height, to keep the weight on all 4 wheels as even as possible. Now damping is different as that will change how quickly the suspension is allowed to compress and rebound, but it does change how the car handles and feels and you can dial this in to your preference on any given surface. For example on a very rough uneven surface, you would want to run softer damping so the suspension can load and unload quickly which will help maintain the tire's contact with the ground. On a glass smooth surface you could run more aggressive damping as you won't have to worry about the tire leaving the road over bumps.

And I will measure the height of the car here shortly for you, but I was able to find a member who measured stock height from center of the wheel to the fender. #SVThis measured:
Front 14 5/8 inches
Rear 14 1/2 inches

Now this may vary with the amount of fuel, accessories and other things in the car, but that should be a pretty close measurement for a stock car.

And we adjusted ours based on the looks to be honest. I am not the best at determining what looks best, so I had some other guys look at the car, and they said "lower in the front" so I adjusted it until they were happy. It does look great for sure, but I imagined we sacrificed a bit of handling in the name of "looks", but it is always a compromise. The car does look fantastic, so I am not complaining

Thanks again,
Rick

Anyone know the part number for the Street Flex?

These are straight from the tein website:
Street Flex: GSQ54-51SS1 $1580.00
Flex: DSQ54-61SS1 $1790.00
MonoFlex GSQ54-F1SS1 $2300.00

I'm debating whether to get the street flex or save for the monoflex. Had the regular flex for the miata but i'd really like a more comfortable setup for daily driving. Gonna do a few track events stock the next couple months to learn how to drive the car stock since its more car than the miata was then mod as my driving skill progresses.

Do these come with front end links or would i have to order those also?

We used our factory endlinks, but if you wanted to go aftermarket, you would have to order them separately.

Thanks,
