Tein Coilover Spring Rates
http://www.tein.com/ti/h98.html
ok, so i was originally looking at the Tein Type Flex coilovers with the EDFC because of their adjustability and I've heard they can be pretty stiff, but accoring to the Tein site, the spring rates seem a little soft to me.
Type Flex - 9kgf/mm....front 5kgf/mm....back
seems a little soft whearas the
Winding Master Mono Flex - 14kgf/mm.... front and 8kgf/mm.....back
that seems prob a little more for me, other than the
Circuit Master - 22kgf/mm...front 14kgf/mm..... back
The type N1s are like 24kgf/mm...front and 18kgf/mm/back... prob a little too stiff for me...
anyone know why the spring rates are more for acura rsxs in the rear? i guess just weight balance.

The Tein Flex is a very good street suspension setup, but there are better options for the track. The mono flex is a very good option if you want to maintain drivability on the streets, yet have good performance on the track.

im talking about a full coilovers, charles which have the shock included. the whole idea i want coilovers this time is so the springs that come with it are tuned to the valving of the shock so when its on soft, it will be firm, but not harsh... and when i put it to max, it will be harsh and firm as hell..
anythought on the Tein Mono Flex? I think the spring rate seems a little better for the track, but to me, it still seems a little low in the back. i mean, i am looking for th best compromise of harcore track performance, but somewhat streetable on an everyday basis... like i said before though, i don't mind firm as hell.. thats what i want.

Coilover is still, coil over shock. Everything is coilover unless you have shock body and spring separated (i.e. Echo/Vitz). Some shocks are made so that it can work with higher spring rates. And when you have a properly matched combo, the ride won't be harsh.
That's what I am getting at, a high spring rate adjustable coilover will still be streetable if it was manufacturered properly. You can drive 18/16 on the street all day long and won't feel the pain.

I don't know much about Tein, but that spring rates looks fine to me for track use. Regardless what you use, you need to fine tune the driving style that suits you, by doing multiple laps and such.
When you have high spring rates, you need really good tires. Or else you will still be sliding all over the place.

14/8 is a very good combo for street and track.
Tein is a very reputable brand, so you dont have to worry about quality. There are other options out there, but you can't go wrong with a solid Tein setup.

yeah, well, it does say on the site that for optimal results out of the coilovers you have to use them with some good tires. Well, I am picking up some r-compounds anyway so i think i'll be good in that department.

I've always seen softer springs in the front and stiffer in the rear for fwd cars.....watching 'best motoring' and taking a close look at some of the fwd race cars at mosport...
I'd go with a 9k front and 11k rear for street use, and maybe 11k front and 14-16k rear for more track use.

I personally use 16/14 and I don't get much under or over on the track.
AutoXers tend to go harder on rear because they want to spin out the back end faster on a very tight hairpin. You enlarge the hairpin to a track size, it turnes into a dog leg or a large curve and that translates into "drifting" or plain out right oversteer.
You don't want no under, over, or drifting on the track, you want to hug the corners and make sure all 4 wheels are on the gruond all the time.

But most others I've seen them run on the touge are alomst balanced front and rear or are slightly higher on the rear....to get the car to 'rotate' more. It is also a preference too. Some ppl like a tight or slightly understeering car, and some prefer a more loose or slightly oversteering car. Obviously, excessive of either is not good.
I'd try a set of springs you think may work well, whatever they may be. Then when your happy with that, use a good set of 2 way adjustable dampers (where compression and rebound are adjusted seperately).
I wouldn't worry too much about what spring rate to run, but I wouldn't run super stiff, like anything above 20k on the front or rear.

thats exactly what im getting at... i think 14 is good for the front, but the 8 in the back seems to soft... but im assuming it would tend to be the cause of understeer. i am running the lsd in the front which helps with that for sure
and if i am runninig the full swaybar setup... with the subframe reinforcement i wouldn't want it too stiff in the back i guess since my rear will be the more rigid part. maybe the 8 would compliment it???or can i get like a 12 or something for the back.

Ask for optional spring upgrade when you decide to purchase.
But regardless, don't focus on the number too much, it won't do much for you until you drive it and fine tune the setup.

well its the tein mono flex... so as far as i know, they come pre-assembled with pillow-ball mounts so i dont know if i can just get different springs when i purchase them.
i mean the tein website says its for circuit racing and tarmac and etc but also for aggresive street. i assume tein has tested it and it works? i don't see why they would go so soft... 14/8.
the next tones up are a 24/16 then 24/18 i think thats still soft compared to the front...

Frankly, I would rather buy from a name brand that only has 1 type of adjustable coilover (or 2) and be done with it, which also allows you do pick the spring rates you like when you buy (i.e. Spoon).
Showa makes OEM Honda, Mugen, first gen Spoon and many other name brands out there for suspension kit. Kayaba (KYB) is the world largest shock manufacturer and also makes Spoon 2nd gen adjustable coilover so it is another good brand I would look into.
Then you have Moton, who just came out with an entry level suspension kit where the professional kit is 1000+ USD per side (only dials "soft" and "hard").
Not knocking Tein, but they have what, 10 different setups? Track proven is a selling slogan, it is proven by their racer, but their racer ain't driving your car.
