so I did quite a bit of reading and decided to switch from function and form type 1's to tein street advance...


did I make the right choice?


I wanted something that would give me decent/good ride quality while being dropped 2 inches...
the streets in the city I live in aren't the greatest, our winters destroy our streets and I drive my TL all year around.

 

This is something you should have asked before haha, I'd say yes and no, the Teins are better quality and are damping adjustable but the design of the f&f's would be better because your the ride quality wouldn't change depending on the ride height, for the money I would have gone with Megan's but Teins are a good choice either way compared to f&f's

 

I think the function and form is a very cheap product... ive had to replace the shocks twice within the last 12 months.

I know the ride quality doesnt change depending on the height... thats not what I meant. I meant that I wanted something that wasnt as stiff as the f&f's while being dropped 2 inches.
But thanks for the feedback. I spoke to the guy at heeltoe auto and he highly recommended the tein street advance for what I was trying to achieve.

 

Only problem with the Tein SS and SA is that the ride height is adjusted by changing the pre-load on the bottom of the spring. The lower you go the less damper travel that you have.

I just took the Tein SS off my car today and replaced them with BC Racing BR coil-overs with the swift spring upgrade. I went with BC coilovers because the adjustment is on the bottom of it, so I never have to mess with the pre-load on the spring. That translates to me keeping the full stroke of the damper as I go lower.

Teins are also all twin-tube designs, mono-tube like in the BC Racing BR is better

They're a pain to adjust though, I adjusted them twice today trying to get my ride height where I want it and need to do it one more time tomorrow. Since the adjustment is on the bottom I have to loosen the fork in front, get some play in it, adjust it, reconnect it, re-adjust the pre-load on all the bushings and tidy things up. The rears are the difficult ones, there are 5 arms on our multi-link rear suspension to adjust the pre-load on.

Hopefully it'll be on spot the next time I adjust it. I'm keeping some data as I go along so I can see how I adjusted it and where the ride height moved to. To hopefully make it easier for myself in the future.

You can get a little more damper travel out of the Tein SA by cutting down the bump stop a little. By removing only the smallest nub on the bump stop you'll get about 1/4" more travel. Don't want to completely remove the bump stops though, I had cut down the bump stop on the fronts of my Tein SS coil-overs.

 

yeah bc is the way to go, you get a full monotube coilover with aluminum top hats for $100 more than the street advance

 

you did well bud...

tein makes a quality product...I had Tein Basics for about 85K miles (4 years) and loved it...I wanted to be able to adjust dampening and preload and hence I switched it out with ISC N1 coils...

but Tein is a great product

 

So is the swift spring upgrade worth it? With that price you could go Tein FLex

 

for comfort you made the right choice, i hate my f&fs....

 

I have tein sa for a little under two yrs and im dropped about 2.25 all around and im content with the ride quality, you'll get your moneys worth.

 

I think the BC BR is a better option than the Tein Flex, the flex is again a twin-tube coil-over. It does have the same design as the BC BR to maintain the full damper travel as you go lower since ride height is adjusted by changing the length of the coil-over instead of the pre-load on the spring.
