Eunos on heat

[Joem]

Is it possible to purchase height adjustable shocks for the rear of the car only? I'm running koni str.t shocks and springs at the moment and the back end sits up higher than my dog does when she's on heat. (handles well, looks rubbish)

[MX-5 Lazza]

Yes it's possible. Is it a good idea? Not so sure.

[Joem]

My thoughts exactly. Does anyone know if eibach lowering springs are compatible with koni shocks?

[MX-5 Lazza]

Ask someone like Gazman (Derek from Gaz Shocks).

[OnlyMX5ives]

Yes it is.

But it would be far easier to simply cut your existing springs.
(Depending on age, type, height etc)

Watch all the 'experts' say how this will ruin the handling and that you'll die horribly.

Strange how I never have.

I have a set of Eibach lowering springs already. These are however currently for sale so a couple of interested parties may be annoyed.

[snotrag]

Although not proper 'coilovers' (ie infinitely adjustable) dont the Koni shocks have a 3 way adjsutable spring platform?

Most cars tend to ride a little higher at the back anyway - the weight on the back will change much more between empty car and driver to full car and a passenger, than the weight on the front will.

[Joem]

unfortunately they have a fixed platform. the back end sits higher than stock, but the front sits about 30mm lower. The car looks ridiculous. I realise that everyone now going to tell me that the springs are the wrong way round.

Are they?

[Joem]

Nope, you'll see what i mean on Saturday if you are still going to portsmouth.

[MX-5 Lazza]

I'll be there. We have a few thi gs to sort out with the PlanetMX5 Motorsports car

Cutting the springs WILL weaken the spring, that's the problem with cutting them They're designed as they are for a reason.

Incorrect.

Cutting the spring increases its spring rate.

I have run cut springs for years as have many others, its been debated at length and its fine if done correctly.

[Joem]

I am quite loathed to cut the springs as although it can probably be done, i'm not the greatest engineer known and can get a little carried away with the powertools.

[MX-5 Lazza]

Not sure you'd want cut springs at the back only anyway unless you REALLY enjoy oversteer.

Trust me, I work in precision-engineering and you will weaken the spring by cutting coils out of it.

But I'll leave you to it

[Joem]

Right, i've fitted the eibach springs to the koni dampers, the car no longer looks like it's searching for truffles and the handling is less twitchy.

All i have to do now is explain to all interested parties that the springs aren't sale anymore.

I work with cars and reality, its fine.

Even the Tech advisor to the OC ran cut springs on his car for many years.

[J-Tuner]

I could only see a real-life problem with cut springs if you cut the tapered part of a spring out (if the car uses them) and it cant seat on the shock anymore (my old supra had a tack weld holding my springs on - the weld gave in and it fell on its bump stops on the left front!! feck ! Got rid of those ASAP.

The other effect when cutting those types of springs is you lose the progressiveness and they become bouncy and ste if you cut them too much.

The other consideration has been mentioned, spring rate and the effect that has on damping etc.. and as above i have witness this in effect first hand. suppose if they are the same diameter all thE way down the spring, and they are cut only a small amount it probably isn't going to be a massive change to damping requirements other than a slighty more stiffer ride?

Its not something i would get into myself these days though
