I have been driving on coilovers for over a year now. I have whiteline group 4 s with race-spec spring rates and damping, so my spring rates are 9k front, 8k rear. I think the tein flexes are 10k front, 8k rear, so a little stiffer.
At first driving on stiffer suspension was bearable, but I can now honestly say that it is driving me nuts (harrrr!). If you are not planning on competing with the car you should seriously think long and hard before you go with higher spring rates, especially with the crappy california roads. If I could do it again I would go with something like whiteline group 4s with the standard spring rates. |

Eibach springs are about $60 each, so you could easily go to a 20% softer setup for about $250 if the 10/8 rates aren't ideal for you Dan. As far as the "new inverted Teins"... I think those may be the Tein SuperRace coilovers (unless there's another set of inverted Teins coming). I bought a set of the SuperRaces about a month or so ago. They're *fantastic* but they're also retardely expensive, and have far more adjustment than you'll need: caster/camber front top mounts, camber rear top mounts, inverted double adjustable 50mm struts, independent right height/spring preload adjustment, dual EDFC capable, 12/9 spring rates. The Tein Flex's are more than enough for a street driven car, and half the price of the SuperRace coilovers.

http://suspensionparts.info/archive/...php/t-273.html Essentially, with a monotube you get more precise low-speed damping, and more consistent damping rates as they heat up. With twin tube designs, the nitrogen and oil are mixing, and can foam up easily which affects damping. Also, monotube dampers have more oil volume to deal with increased heat. Inverting monotubes is done to both decrease unsprung weight and strengthen the unit, at the expense of slightly greater total weight for the unit. It is something you will normally only see on strut McStrut suspensions, as there are no lateral loads on a standard shock and therefore the extra weight brings no advantage of strength.

I think they were the monotubes. but there isn't a suby application listed on the site. paul said a couple of hundred more not twice as much so it's def not the super races. I'd be all over those or a set of fully adjustable ohlins or KWs if I was competing.

The new Teins are called "winding master Mono Flex" and basically, they're a single adjustable version of Scott's dampers, only way less expensive. I would definitely choose those over standard Flexes if the price isn't unreasonable, which seems to be the case.

Just cut y0 springs!
seriously though. I've also ridden in a lot of "Flex" Cars they are nice. I'm with MikeK in the department. Having gone back to my stock setup I love my cush ride. I really liked the Eibachs I had. If I end up keeping my car I won't be putting coilovers on it again, even though I will track it. Plus I remember doing thunderhill on my eibachs and keeping up with all kinds of horrible drivers on coilovers by just driving a good line. I thought I was a hardcore motherfucker but the stiff ride just go to me after 6 months or so. So in conclusion. I don't like coilovers, although they will get the max performance. It sounds like you are replacing you whole suspension anyways so I doubt you will be getting stock struts again since you'd have to buy used ones or crazy high prices for new ones.

Twin tube, and monos can both be good depending on your needs/requirements.
And there is actually data to support twin tubes being better for daily drivers due to their better ability to respond to normal road "noise" such as truck ruts, etc. where monos might tend to "bounce" http://www.whiteline.com.au/faqshock...haracteristics. Beleive it or not, there was a good article on this in a recent Compact Car as well. For your needs, I would stick to the Flex.

My civic was stiff. I had koni yellows with some nuespeed race springs. I have no idea what the rates were. doesn't matter I guess because the scoob weighs what feels llike a thouzillion pounds more. But the civic was very dampened (i cant speel so fuck off). You'd go over the back side of a high spot on the road and the car would drop to follow the road but there was very little rebound bounce. Unlike all of the other cut spring rice buckets back in the day. I'm still working on purchase authorization from the wife.

I have Tein Flex's now for two winters. I raised them slightly out of the box. The only issues with lowering a car in the snow is with wet snow during the day and freezing in the wheel wells at night. This only happened to me once and it sucked. That said, the ride change from stock on the softest setting is still much stiffer, but not as bouncy over washboard snow as the stock setup.
The only time I am stuck in the snow is when the streets are deeper than the cars clearance with heavy snow (pretty much the same rule of thumb for any car). I've driven it in light snow where the snow was coming up over the hood. I've also high centered in 6" of heavy wet mush.

I'm with Tyson. . .
Having run coilovers for a while and taken a step back to "street performance" springs (I have Prodrive blues on), I can say I prefer a moderate spring/strut setup to coilovers. I really didn't end up using the coilovers' adjustable bits, and in retrospect the street quality vs. autox performance may not have been in my favor (way more time on the street, obviously). I forced myself to get used to the rough ride, but after a couple weeks on the Prodrives, I was pretty pleased with my step back. I'll be adding a set of adjustable struts when they exist for MY'05 to maintain a good street/autox balance. Since autox isn't an issue, you really don't need coilovers. Also, keep in mind that the dampers on coilovers may need to be serviced more often than you'd need to replace OEM struts. I'd say grab a set of Prodrive springs and some new rear struts. Even if you're just replacing with another set of OEMs, you may find it a better personal value for your money.

I was reading that same thread this morning on iwsti...
That's not far off from my setup, with the exception of the x brace, alk and a few different brands. All In all, my car hadles well on the track, street and auto-x with just a few tweeks here and there. I can imagine the X Brace and ALK make a great difference on the track, and I'd like to try them, however they are illegal in my autox class. If you're just tracking the car though, that is an awesome setup.

The key thing in that post may well be the:
Whiteline 27-29 front sway, stiff setting. The other components are pretty standard. I wonder if the Strano bar would make it even better...

I'd be curious as to how it would compare to KW V3 race rates with 22f/24r or similar sway bars.

We have custom spec'd KW's as well if anyone needs some

Mike, I'd be extremely interested in a set that would work the best in your opinion with my OBS... PM me!

As far as I can tell the tarmac IIs have differenct valving, external reservoirs (on the fronts) linear springs front and rear, double perch rings to lock rather than a single with a set screw. I remember you had some KW's on the race car with PDE camber plates. |

I ordered the T2s with 400/350 rates and Group N rear tops. I'm looking into PDE camber plates for the fronts.
