Redline360 why is it with different store they tell me different specs ehat is the drop for basis z

[@TylertheGeek28]

This 4 minute video gave more info than other videos that were 20 minutes lol

[@markhondaturbo]

You could have went over the differences in how the height is adjusted. Like why a threaded shock body is better or worse than a non threaded shock, and how they effect travel and preload.

[@balancemode4112]

i just installed GSL90-9USS2 Tein Street Advance Z Coilover for my Lexus IS250, it was the best coilover i’ve ever used😳😳 so smooth and comfortable after my Rev9 coilover blew, never going cheap again on coilovers Tein is the Best

[@demainmyhlem5930]

can you camber it with that coilover?

[@250tsar]

I’m thinking of buying tein for my 250 lol

[@DISOPtv]

BUYER BEWARE: Struts were missing a nut and a collar. Adrian from TEIN refused to replace them. They claim it was shipping damage, but they can't prove that they even put them on the strut because they should have been screwed onto the shaft like the others. Shame, literally costs them pennies to replace and they refused on a brand new set of struts.

[@mrman8856]

I love my Flex Z's for my 2nd gen gs300! Once I got my height, dampening, and alignment dialed in they ride so smooth with a stiffness that's BARELY noticeable until you really use the car going around a corner.

[@keelengaines2824]

I plan on getting an 06 STi. I'd still like to go fast even though I'm going to daily drive it. So probably the Advance Z shocks are for me.

[@dippah1]

Long time fan of TEIN. I’ve been out of the Honda game for some time but glad to see the R&D game is still strong. Looking into this for a friend with a 2023 Civic and for the person asking about Lexus…your car weighs more so you don’t want anything entry level. Step up and stay safe!

[@Rafaellasvegas]

Thanks for mentioning the Street Basis Z is still a comfortable ride... that’s exactly what I want besides being low. Plus itd be a replacement for my stock suspension

[@picolrallyteam5821]

Am looking to get basis my oem are abit soft where basis a little stiffer than your oem

[@kp7interests]

This was great video, straight to the point, Short and full of information.

[@brian.z6592]

Short but very informative video, thank you!

[@MJ-iq9hv]

Woa awesome prices! I’ll be ordering the flex ... thank you so much because I was wondering what the difference between them was ... I had the street advance coils plus Skunk2 rear camber arms + front camber bolts on my 2014 si coupe ... now I just traded it for a 4 door 2013 si turbo on stock suspension 😝 lol ... and I liked my street advances but I’m trying to make my suspension even better this time around I had no clue the flex were made in Japan with better materials! So thanks 🙏 I hope they are even better

[@zacmich6472]

I want less bodyroll in corners than with stock suspension. Would the Basis Z be enough for that?

[@freewayron]

2015 si sedan, lookin to lower the car but still have the comfortable street ride not a stiff bouncy ride...what do you suggest?

[@djalifam-alient.4759]

Does the flex Z come standard with camber plates for a 97 Lexus sc300 or is that an add on?

[@premthivagar1294]

Hi Bro .. Thank you for doing this.. Could you please tell me that how long will it last

[@FlipSideGarage]

I need a set for my 2012 TL non awd. Will the tein basis need special preloading before install or can be installed right away,set at stock height then adjust?

[@sotamods-TMH]

Can you tell me if there are any interchangeable springs for the Adv. Z for the Altezza? The springs are the same as the ones from the Basis Z and are soft as f**k and though the 16 step damping of the dampers works quite well the kit is still TOO SOFT. Unfortunately my supplier/seller is a useless and unreliable guy and doesn't give me any support in that case :( I also installed front and rear strut bars but while cornering simple on the road the car is still swaying like a 20 year old sofa :( I guess the springs from the Flex Z kit have different diameter and I'm not sure if any springs from an Aristo kit would fit or make any difference. So I'm desperately looking for help!

[@kriskaylor6679]

Good video, thanks my question is how does the advanced z compare to the ohlines coilovers?

[@carvinstone525]

Great input, very informative and this definitely helps with my decision. Thanks Bro

[@decaygrim8943]

I researched hella prices online and redline has the cheapest flex z suspension for my vehicle

[@cesaryb8933]

For the basis z I know it doesn’t come with the top mounts, would recommend using the stock ones on the vehicle or buying a new set of aftermarket top mounts and if so which ones

[@TheFoxho]

Same price as BC BR. Anyone compared the performance of these shocks before?

[@wutdafeezi]

Can’t speak for BC but damn Tein Flex Z is worth every penny no matter which car you drive

[@robinlopez1909]

Thanks, you helped me to decide wha to buy.

[@Prazdaa]

I just got the flex-z Teins for my Scion tC. I'm so excited to have them on my ride. I will update this comment once they are on. Redline360, big suggestion, when shipping suspension, use better packaging please. Couple deep paint scuffs on the springs themselves from shipping. Box they came in looked like it was rolled down a hill and thrown in the truck. Obviously not your fault, but better packing would help.
