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

    • Hey all, I'm sorry if this has been discussed before.  I have a 2008 Japanese import V36 coupe with nav but without Bose. I bought one of those AliExpress android screens, which for the most part works really well.  The only thing that doesn't work is the air con controls (well sort of) and the factory reverse camera.  The AC can be controlled fine but it doesn't report the change in temp and mode to the screen, and the volume knob/other audio controls from the panel don't register on the learning app.  I am pretty certain that the problem is the difference in the head unit between base model (Nav but no Bose) 2007-2009 coupes and anything after 2009.  Mine is the one with the blue connector all the way to the right as seen in this forum post:  The reason I think this is there is one wire left over that doesn't fit anywhere on this head unit, or in the factory screen which also uses different connectors to more recent versions.  I've seen the upgrade from OWC, and have sent the guy a message on eBay but no response yet.  I also don't particularly need the whole kit, just *maybe* an adapter for this one cable.  Did anyone else here have the same problem, or have any insight about what I can do to get this working?  I have been in contact with the seller but all they seem to be able to do is ask for more pictures and videos. Minor edit to add:  I have been researching and found a screen on Aliexpress that actually specifies my head unit in the listing, so these things do exist.  I will contact the seller to see if the wiring adapters are interchangeable with other screens.   Thanks in advance!
