I just want to clarify something. In your last post you indicated that the CS springs are softer, I am assuming then the Flex and not the L-tuned. If they were softer than the L-tuned there would be more body roll in the corners with the CS than L-tuned (this would not be consistent with Neo's observations).

I think Cong and LXOGOOD has the CS/TRD combo and they liked it. I can't remember if they had all the lower bracing though.

Although I can't remember seeing the specs for the the L-Tuned, I think Bit is comparing CS vs Flex. The spring rates on the Flex (10/9) and CS (9/8) area actually not that far apart (compared to HA: 14/10) but the shocks are setup differently for the appropriate ride/handling characteristics.

According to these spring rates there should not be much difference in the "body roll" factor between the Flex and CS. Am I correct in this statement? This would also mean there should be a noticeable difference when comparing the L-tuned and CS with the body roll and not just a light difference. In reading the TEIN charts as far as the drop with the CS it doesn't seem to have much more capability than the L-tuned. Again am I reading the charts wrong?

BTW Neo this is a great help for me thanks again.

Although the difference is only 1kg/mm^2, I easily noticed the body roll change. I can't say I can compare the body roll differences with the L-Tuned and CS since the L-Tuned/TRD sways combo I had for awhile was pretty effective. In terms of body roll, I was pretty happy with that L-Tuned/TRD combo. I changed out to Flex since I wanted to have the dampening adjustability coupled with the additional lowering.

As for the CS lowering, even in my current "raised" state, I have it lower than when I had the L-Tuned. AND, I still have room. I think I can go almost no gap if I bring it all the way down and I am only running 18s. With 19s or 20s, the CS has plenty of room to go down, as long as you are not going for the tucked/slammed look. When I had my Flex, I ran pretty much almost no (less than 1/2 finger) gap front and very slightly tucked rear. Driving around town was starting to be such a pain that I've raised it when I got the CS. The ride is much more manageble now that I'm pursuing larger wheels vs. lowering the car to reduce the fender gap.

Your experience is really helping answer many of my questions. I will not make my final decision until my RMM STB, TRD LCB and TOM'S LCB are installed on the car. I will compare the effect of these with my initial suspension mods and go from there. An interesting comment on TRD vs DAIZEN sways (I know this topic has been debated many times). I am wondering whether the ride quality will improve for me as much as it did for you with the CS as I am going to keep the TRD sways?

Thanks again.

Mario
mario,

i can't say about trd and daizen sways on the CS. i had them on the car when i had the flex, and i could feel the difference between the two set of sways on the flex

well between the CS and the flex, i felt a bit more roll on the CS, BUT, BUT, BUT, that's on very hard cornering. on normal fast speed cornering, to me, i can't feel any difference. on the other hand i could feel the difference even on fast speed cornering between the flex and the HA. hope that helsp

YES, YES, YES!! This is good. I am definitely "leaning" towards the CS now (no pun intended). Bottom line is that I want to have a noticeable difference in handling, cornering and ride quality in order to get rid of my almost new L-tuned shocks and springs. I just don't want to waste money on something that I may barely notice.

Awesome Rominl!!

What are the price differences between these 3 setups? If there is even any? I would assume that it'll be very similar with the CS being the least expensive?

Are you talking about hte three in the title: HA, CS, and Flex? If so, pricing goes in that order too. CS and Flex are pretty close though (around 1300), maybe $50 between them. The HAs can be had for 900-1000 I think if you can find them. I don't think they are scarce but I believe Tein has also discontinued them.

Oh, and these are new pricing. Obviously, they can be had for less used.

no way, the CS is definitely not cheap. price has nothing to do with comfort remember the HA doesn't come in the COMPLETE form, meaning it doesn't have pillow mount, etc... so it's the cheapest. you can probably get them new for around 900 to 950, but they are discontinued item so tein will have to BUILD It for you, not sure if that will make it cost more

on the flex and CS, you can probably get them for aroun 1300

Hey guys, i found this graph that depicts the performance characterisitics of all of the Tein gear that is discussed in this thread. I'm sure many have seen it before, but I thought it would be helpful on this sticky:
