i am looking for a spring rate for a full coilover that is very streetable but still gunna be fun at an open track day.... i was thinking 8K 6k... BUT some people are telling me to go 10K 8K.... lmk what you think... thanks

 

I run roughly 8k/7k on my 94 Integra daily/autocross car. It's tolerable to me for daily driving, and I feel it handles pretty well. The instructors at the last Evolution school I attended all said it handled well, too. For my comfort level, I would definitely not want to go any stiffer on the rear for daily driving, and this is in Florida where the roads are reasonably smooth.

 

You reaaaaally wanted the higher rate in the rear. I ran on a "JDM" setup with higher rates in the front, and the car felt OK some places, was good on the street, but at VIR, it just didnt wanna turn, you can forget any track time in the rain, it just wanted to PLOW.

I run Koni Yellows, and GC with ERS at 450f/550r, and its very livable on the street, and currently still feels to do well on track.

You're best to go mild on suspension, and improve yourself as a driver, then build the suspension around your driving.

I agree, get something that handles aggressive driving (track) yet not race car rates.

Also, as far as what spring rates are too stiff, that's usually very subjective. What's comfortable for one person may be very uncomfortable to another. Seems the track oriented ppl tolerate much stiffer suspension on the streets. Maybe because they're used to it. My GSR has 450F and 600R with revalved non-adjustable shocks. I can handle it just fine in street driving if I need to use the car for that. The only thing I can't handle is the lack of A/C in this CA heat.

You're crazy for the bold text.

I don't mean to thread jack, but when people say they run 8k/10k/etc for their springs...what does that translate into when people say they run 500f/400r/etc?

 

1kg/mm = 56lbs/in

 

I run 450F/400R on my car and as long as it's not bottoming out (it was too low at first) it rides fine. As for higher rates in the rear? It's a matter of personal preference, but the higher the rear rate the worse it will ride.

I also have an ITR 22mm rear sway and no front sway, I feel like the car is fairly predictable and will oversteer when I want it to.

 

A number of us who started track driving our DC2 ITR about six years ago were really very happy with 400# F / 500 # R.

It provided a significant improvement on the track when used with either Koni Yellow or Bilsteins, but it was also really quite streetable and comfortable if we still commuted with our ITR.

We all moved on to other things now, but we all also remember how excellent this was for a mixture of street and track driving and we do not hesitate to recommend it to other people facing that kind of environment.

 

&lt;- 450/550 here, and couldnt be happier.

As to those running less a front antiroll bar, I just dont like the way the car feels without one. I run a GSR/ITR 24mm front, and a Progress 22mm rear. The car is very much neutral, and predictable, while still being able to induce rotation when wanted.

I'd be crazy, but it's no longer a daily driver. 99% a dedicated track car. Still registered and insured but only sees street driving if the daily and weekend drivers are out of commission. And on the way to the track and back.
