By streetable I mean very limited street use, with no real concern for ride harshness. Ive been told these rates in the rear can really make the back end want to kick out on uneven surfaces. Anyone using 18K rear rates on the street? Or should I just stick to a more moderate rate since the car is a street road course and drag car.

 

You would be better off buying the sport kit and putting the rear in the front and front in the rear if it will be driven on the street a bit.
I put one set of drag coil overs in a EG before and at 70mph down the highway it was almost impossible to keep that back end on the ground (Highways in RI are very bad) but anyway I would not leave them in for street use, most people just swap those in when they get to the track.

 

Thanks for the info. I assume you are referring to swapping the springs themselves? Wont that mean the damper rates wont be matched to the springs and just wear out the dampers?

 

i have them on my hatch and it was daily driven for a while

 

i used to have them onmy SFWD car. they are ok if u dont plan on using the car very often, and its mostly a track car IMO..

I mean, of course you COULD use them as much as you want, as long as you dont mind migranes and minor kidney failure

I've been daily driving my hatch for two years with 900lbs springs in the rear and it's rough as hell. My wife hates riding in my car.

 

Drove my car almost every day last year on 18k springs its not soo bad.

 

I daily drive on the 12k front/18k rear setup in my 89 crx dx. Personally they are a bit too stiff for the EF chassis. They feel alot better in a DC/EG chassis.

 

Just put them in my DC2, I haven't gotten to the track yet, let alone really have even driven the car being my current seat right now is a cardboard box

I did take the car around the block and it wasn't that bad at all, I say go for it

 

my rears are about 900lbs they are pretty stiff....soften the dampner up a bit and it helps on the road

 

I believe its horrible on the street,forgetting the ilovemycar blah blah; compared to other cars, 18k gets really bumpy as said earlier backend flies up and down so does your organs =P

 

I drive my car a lot with those springs. its not the most comfortable but I dont mind it anymore.

 

I have a 2000 Civic Si and have some Skunk2 500lb/in fronts and 900lb/in rears and KYB AGX adjustables set to full stiff all the way around, drove around on the street for a couple of years no issues for me. Someone in the back seat may hit there head on the ceiling when you hit those bumpy highways , You wouldn't want to take a DRUNK person for a ride in it I don't think lol

It all depends on personal preference, I drove around with many unsprung 6 puck clutches before and also Twin Discs on the street so what I consider streetable someone else will be completely disgusted with!

 

Im a 6 puck unsprung clutch kinda guy too

Ive been discussing this issue with a few people on the board and apparently the damper is what really makes the ride bearable, or not. As long as you have an adjustable damper of decent quality you should be able to tune the setup and make it "comfortable" enough for the street.

I havent decided what setup Im going with yet though.

 

Alot of the answer follows under whats the road conditions like in your area..If the roads are ruff the ride is gonna suck..I drive around with mine but thats me, doesnt seem to phase me..

Definitely not, although you only have to DD once before people say "expletive that never again."

 

I have them on my hatch with KYB's also. Not too bad. Word to the wise though......dont drive around turns too fast with your skinnies on the back! Took the 2.5 hour drive to Englishtown 2 years ago with the skinnies on the back and almost lost it on the first curve at 50mph 10 minutes into the trip, closest to drifting I'll ever want to be lol To make matters worse the girlfriend gave me a nice shot in the arm and argued with me for the remainder of the trip

Thats why you put the street tires on the car and the skinnies on the passenger side seat (where she was), lol.. problem solved

Good call

 

I'd say if you have really stiff springs on the back (like the Omni Drag kit), be careful on the street. The back of the car is very unpredictable and likes to hop around (especially on on-ramps with bumps).

To the original poster, its not easy to make a car that is a street/road course/drag car. I think you should figure out what you want to do most, and move in that direction. Either that or be ready to swap springs out a bit.

 

its not that bad i would suggest getting a harness in the car and some nice seats if you dont already have them, cause i would hit my head off the roof sometimes when i hit a nice bump or an uneven spot in the road
