I have a set of TEIN HA coilovers with 560lb and 670lb springs, I plan on putting these on my 2100lb w/o driver '93 hatch. The car will be seeing some auto-x and lapping events but will also be driven on the street from time to time. I am concerned that the rates may be too high for the street use it will be seeing and I am also a little confused as to whether I should but the 670lb springs in the front or in the rear. Anyone who could shed some light on the situation would be of great help to me.

Thanks, Mike.

 

Those are at the upper limit of what i consider tolerable, however if your roads dont suck, then they will probably be fine.

Just be honest to yourself (if not to us) about what kind of time this car will see at an autocross, HPDE, and on the street. If this car will see 8 minutes/month of autocross time and/or 60 minutes/month of track time, but you drive it every day all over town you're really compromising comfort. At that point, I would almost be tempted to swap springs before an event. However, if you're seriously only going to drive it on the street 1-2 times per week or less, it's tolerable.

 

The rates are a bit high for daily use.

As per your question on where to put the springs. are you running any sway bars??

if not then i would reccomend the stiffer spring in the rear

DISCLAIMER!!!!: This will cause MUCH more lift oversteer. Its needed to be fast but not good if your an inexpierenced driver.

For an arguably safer car the stiffer spring in the front, also this setup if you have a big rear bar.

 

Okay guys thanks for the answers, now if I was to look for a slightly less aggresive set of springs where would be the best place to find them and how low a spring rate can I go with the TEIN HA shocks??

Thanks, Mike.

 

Ask here.

 

bump.

 

Call Tein and ask?

 

Personally... I wouldn't want to run more than 400-450 lb springs in the rear. Everyone has their own definition of tolerable though.

 

Just trade me springs... I'd be happy to drive around with spring rates that high. : )

But my sportline springs are fairly tolerable, I don't know the exact spring rate, but they serve their purpose autocrossing, and aren't too aggressive on the street.

 

Well I would be willing to trade but I am still unsure how low a spring rate I can go with TEIN HA shocks, I have tried to call but they haven't been of much help to me. They also don't seem to like replying to my e-mails.

Springs that sit on an OE spring perch arent interchangeable with a threaded sleeve/shock+perch setup.

 

Have you tried adjusting the rebound/compression?

AFAIK ride quality when considering rates is going to depend on the quality of dampers, or their valving (read: ability to control the spring)..to a degree

ie revalving a damper to the rate you have would make alot more *tolerable*. But I assume this is basically what you are doing when adjusting rebound/compression dampening..

For example I have Koni/GC (350/400) If I turn rebound to full soft, the car becomes somewhat bouncy/annoying. However, turning the rebound to 1/2 stiff is a bit more tolerable..

Are the rates you listed the original rates that come w/the HA?

 

I don't believe they are the rates that come with HA's, TEIN isn't marked on the springs. And the reason I believe they are the rates 560lb and 670lb is because they are marked 100 and 120 so I am assuming that it means 10kg/mm and 12kg/mm. And it makes sense cause they are beefy as hell.

makes sense, usually Tein OTS setups run a heavier rate up front, lighter in the rear..However if you bought them used, the springs could have been swapped.

Of course Im assuming you are saying 560F/670R

Are the springs Tein or some other manufacture?

EDIT: here is a link to the OTS tein rates.

Yes, I wasn't trying to be too serious there.

On the other hand if he wanted to trade his Tein setup for my combo of sportlines and kyb agx shocks, I couldn't decline the offer!

 

I wish I knew the origin of the springs but unfortunatly I don't. All that is marked on them is B100 = 97G (rears) and B120 = 97G (fronts, these being the beefier ones) it is marked on the top of each spring where it contacts the top plate. So I am assuming that B100 is for 10kg/mm and B120 is 12kg/mm. So with that being the only info I have I am really unsure what they may be??

Thanks, Mike.

 

hrm.. you think you could post some pics.

maybe some of the spring experts here could help ID them

 

I will try to get some pics up later today.

 

They might be marked like the Eibach ERS springs. For example OTS GC's for a 92-00 civic come from "200" F and "180" rear. Well I know this isn't 20KG/18KG and I know it's not 200lbF and 180lbR either. I forget what the conversion is but it ends up being like 300-320+F and 250-280ish rear somethign like that.
