What do you guys think of tein flex z?

I prefer professors over meisters myself

I run the V3's along with spl front and rear billet arms. going back I wish i wouldve went with fortune 500's cause the KW's squeak like a mofo

if youre going all out with suspension youd be a fool not to run crazy specs in my stupid opinion.

good luck with everything!!

Are you running a Hotchkis front sway bar? The only squeak I ever had came from the the sway bar and I've had KW's on both my z's.

I prefer monoball mounts on the coilovers

I went the powertrix route because of Charles support and I’ve been happy with them but like most I don’t have anything to compare them against. The thing that turned me off to the V3’s were they don’t give the coil spring rate and then when I called and got someone to give me the rate they seemed rather soft compared to other options and then also they are progressive rate springs which I’m just not a fan of. I tested them in my buddies m3 (he likes em) and I know it is not apples to apples at all but it still had that unsure lean over in turns that I feel is largely due to the progressive spring since every car I’ve driven that has progressive springs has that same sensation. Also his make noise as well. An option that is now available that was not when I got mine is the Greddy coil overs which are using KW single adj. dampers but with linear springs. Otherwise the powertrix have held up well and I believe they are on a big sale again so great time to buy if your looking that route.

Is it okay to install spl front and rear camber arms without coilovers? I returned my tien coilovers n got the front/rear spl. I am just gonna save up for kw3 or fortune auto coilovers

Yeah, it's ok. But you will be paying for 2 alignments.

OptionZero · 06-15-2020, 03:25 PM

if you’re on stock suspension there’s no NEED for them

You are better off installing arms and coils together so you can set the height, then alignment all at once.

Why pay for two alignments?

But i mean theres no reason they wont “work”. Adjustability is adjustability

GooglyMoogly · 07-15-2020, 04:10 PM

hey guys,
So I ordered KW3 and I have spl front/rear camber arms. For kw3 do I need the spl mid link? Also do I need the spl eccentric lockout kit? Tried searching didnt find anything.

OptionZero · 07-15-2020, 04:51 PM

KW v3 are OEM type (spring divorced from coilover)

However, because they use a PROGRESSIVE spring, you get a whacky, varied diameter spring in the rear like this:

For OEM type, coilover owners should get the SPL mid-link, which looks like THIS:

The SPL mid-link requires 65mm ID springs (roughly 2.5 inches)

This leads me to believe the progressive spring will NOT work with the SPL mid link.

My recommendation would be to CALL SPL and see what they recommend. They've always been super helpful.

or you can cancel the order on the stupid KW's and get fortunes or something that have more adjustment range and use linear springs

Rusty · 07-15-2020, 05:29 PM

The SPL mid links only work with straight springs of 2.5", 65mm springs. They won't work with a oem or taper springs.

OptionZero · 07-15-2020, 05:35 PM

right

the SPL midlink/toe arm normally is what takes over toe adjustment.
If he can't use that i think he's stuck with the stock eccentric bolt

the traction arm does stuff too but adjustment is impacted without the adjustable arm there

another reason why KW should not be preferred

GooglyMoogly · 07-15-2020, 05:49 PM

So I called SPL and they said I will have to change the springs to be able to use the midlink. I guess i will have to purchase some Swifts. So guys do i still need the eccentric lockout kit?
