Yep, they're linear, but virtually every automotive spring is slightly progressive. Even those that are defined as linear. Some linear springs have some allowance to being slightly progressive than most other linear springs. The mention of 14kg springs not being too rough for the a long drive is something that sounds great. I was just wondering if the springs on the Mono Flex (asside from the spring rate) has better allowence than the 12kg springs on the regular Flex dampeners.

 

the valving is completely different between the mono flex and the std flex, not to mention one being a monotube, one being a twin. They are completely dissimilar units

 

+1. They way i understand it, monotube dampers are a superior design to the dual chambered dampers.

 

Surprised no one has mentioned BC racing.

Everyone seems to be raving about them lately and only cost 1K.

Dampening and height adjustment

 

I have the mono flex as well. I love them. I am amazed how good a ride these are considering the springs. The valving is perfect.

 

i say buddyclub. i can vouch for quality and performance.

 

Seeing as this is my thread, I thought I'd let you guys know what I ended up buying. I bought the JDM version Mono Flex with 10/9 spring rates. I haven't had them fitted yet, but I'll let you guys know how they are when I do.

 

I was gonna say Greddy or Megan racing, but you got the Tein Flex.

 

Mono Flex not Flex. Also like to say thanks guys for all the help and suggestions.

 

I've used them a few times now, and they are certainly worthy of consideration for a budget oriented setup, but they in no way compare to the Cusco Zero 2, HKS RS and others mentioned in terms of their valving, especially when it comes to running grippier tires, where I found the BC to be underdampened.

As with anything else, it all depends on your uses for the car

 

in the most literal sense, yes they are, but just because one is a mono tube and one is a twin tube, does not automatically make one superior to the other. Very often manufacturers do these things on a marketing basis as well. With something as competition heavy as coilovers, it pays to talk to people who have used and played with various setups, with various tires, on various road conditions to get a real world feel for what each setups strong suits are, to find one that will suit your particular needs.

 

a friend of mine purchased the stance suspension, just over a grand, and is very dissatisfied with the ride. The rear is where his problem is. He didn't say specifically what he hates about the feel of the rear. However, my question is, is it possible to take out the rear springs off the stance shocks, leave the shocks in thei place and put a different spring back in the stock car location? The stance website rated the rear stance shocks at 5k. How many lbs is that? Any other known springs rated the same spec? I hope I'm making sense here.

 

1. Yes, however, how would you adjust rear height? (I know how you can, add's $160 cost)

2. 5Kg= 260lbs,...BUT! you have to increase that rate when you move the spring location inboard to the oem rear location vs on the dampner. A 400lbs spring in the oem location = a 260lbs spring on the rear dampner. (using a
.649 motion rate for the oem location a a 1:1 rate when mounted on the dampner).

2a. Oem 05-07 rear springs are 427lbs. You can use Eibach ESS springs, just pick your rate and free length.

 

OP
how did you go about getting the JDM spring rates? Are these spring rates still compatible w/ the current valving in the monoflex.

 

he lives in Australia

to run such a drastically different rate vs what is included here, you would need to completely rebuild/revalve the dampers
