I have a dc4 (coupe) with koni yellows and ground control coilovers. I have 400f and 320 rear but just changed to 550f and 400 rear. My dc is pretty low and actually rides good on the highway but when it comes to little dips and small holes in the highway my car bottoms out like crazy!!!!!!!!!!! Im not sure yet if its the upper control arms or the struts bottoming out, i havent had the chance to see if the upper control arms are hitting (there old skunk2 adjustable by the way).

I dont really care about ride quality, I just hate hearing my car bottom out like crazy everywhere i go.


How stiff of the spring rate would you guys recommend?

 

Are you sure the suspension or UCA's are actually bottoming out or hitting the shock towers?

I used to run 380 lb. GC springs up front, at the ride height shown below and I had no problems at all, even on rough roads (and there are plenty of those around here). My shock towers have no dents in them at all.

 

how low are you? agree with patrickgsr94, if its your shocks maybe extended top hats?

 

well maybe its my upper control arms. Which ones are you guys running.

my integra is probally 1/2 inch lower than that one ^^^^^. Its also on 15" wheels and the majority of the tire is in the fender well.



i do have koni extended top hats

 

I run 205/45-16 tires, and I had stock UCA's. Also stock top hats.

Be sure your bump stops are cut in half.

 

yeah i cut them in half. i didnt want to run the oem tophat because the camber is off pretty bad



is the uca a common problem?

 

Sticky: No, you DO NOT need camber kits!!!!!!!!
Reading time...

 

wait, what does the top hat have to do with camber? Stock or aftermarket top hats will not affect camber in any way, shape, or form.

 

i meant upper control arm, not top hat lol

 

ah gotcha, yea stock UCA always yields the best results IMHO

 

yeah i might have to go back to a stock control arm. Ill probally raise my car up 1/2" and then get a little stiffer spring rate
