Eibach Vs King Springs

Hi all

I have decided to change my suspention over from a JIC coilover kit to a Bilstein and spring combo . My only problem is what springs to use - Eibach or Kings . The spring rates are about the same the only BIG differnace is that the Kings are liner at the front and progressive at the rear . The Eibach springs are liner all round . I like the concpet of the progressive springs for ride comfort but at the same time a little uneasy by the induced body roll of the top soft springs until enough pressure is put on the spring and the hard spring is hit . Going into a corner you never know what your going to get - the soft or the hard . also the car is Street only

would love hear of peoples view or experiences with either of the two springs

thanks

if its a street only car then honestly your not going to notice any difference between the eibach's or kings.

Most people dont tune suspension with progressive rate springs properly which is why they are unpredictable.

If you select the spring and shock properly when the car enters the corner and weight is put into the spring the progressive section of the spring should be compressed and using the higher rate.

If you have the wrong spring you will end up 3/4 (just an example) into the lower rates travel at entry and reaching the higher rate at midcorner (if you have the grip) then coming back to the lower rate at the exit. This does become unpredicatable.

Saying that if you are pushing hard enough on the street to worry about what the spring is going to do entering a corner you should be on the circuit instead.....

Nothing worng with a progressive rate spring, I dont persoanlly like using them for anything other than a comfortable road car though, they have many adavantages and disadvantages which are far behond a road car, they do however have a valid place in road cars for ride comfort.

If it matters id take eibachs or QA1 springs over kings any and every day.

the king springs are only progressive to keep the springs captive

I had a set of king springs before, with the weight of the car, the progressive section of the spring should close up, like helper springs, therefore the effective rate is still the higher rate

Ive got Bilsteins with Kings and they are perfect. You cant feel any transition between soft and hard as you explained so dont worry about that haha.

The only difference is that the car is nice and smooth when daily and then handles real nicely once pushed through corners.

Go the kings if daily and they perfectly fine to be used on track too

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.

      Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol

      remote oil cooler hose size, 8,10 or an12?

      By MBS206 · Posted

      -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.

      Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
