Trouser @TSL

....Oh yes!!!!.... here they are kids.. the first 50 sets in the UK! ... are they different?.. have a look for yourself.

The picture shows the old fronts next to the new fronts.. and then the old rears next to the new rears. The free length of the new springs is much shorter and the raer is no longer a progressive wind.

The rear wire is .75mm thicker than the 00 kit whereas the fronts are .25mm THINNER!!!! hmmmm






Will fit a set tomorrow on a car with 19"..LET YOU KNOW!

Cheers

So,how much are they fitted to an MY01 then and can you do the Prodrive settings at the same time?
Gimme an all-in price if you can?

Cheers,

Nick..

Trouser

They look ace. Cant wait to get them fitted. Still deciding on date to book them in though!!!

mutant_matt

Trouser, can you tell us what the differences are? Did Eibach make these to your spec or did you tell Eibach what you were after and they came up with the changes themself? Have Eibach tested these?

Cheers,

Matt

All in price fitted and aligned?

As above also how low will the car drop.

Yer go on trouser spill all and tell us mortals how much its gonna hurt the credit card?

BugEyed

OK Trouser. These are significantly different to the springs we had been expecting . So the effect of the change of diameter of the wires is that the fronts will be softer, and the rears harder, than the "classic shape" ones. To increase the effect of the thicker rear spring, they have half a less turn than the older ones, so again will be stiffer.

Any chance you could post up the spring rates for the old and new springs, and an idea of the fitted length?

Thanks

Duncan

PS. The information so far implies that they will give us the best of both worlds - a lower ride height (particularly at the front), with a controlled rear rate in comparison to the Prodrive springs.

Edited to add;

DOH!!! I saw this on the thread in the Suspension section which half answers my question;

quote from Trouser@TSL
I'm still interested in the fitted lengths though ....

me want, how much ????

Dyney

Paul,
Weren't you ment to be making the tea at the time you were posting this. Dave looks so parched he's about to fall over

Iain.

WRXBOB

TSL price is (I think) £325+vat thats fitted and including full geometry setup.

Mine are being fitted April 5th

Paul,
You were probably going to anyway, but, could you take before and after photo's of the car, and either post on here or email me the pics (or do both)
Also, got any feedback from customers with the 19" rims, wanting to know what its like with them on, and after Eibachs fitted.

Cheers,
BOB

MATTeL

WRXBOB - How can you wait that long? I used Northern pleading to get in for the 25th March!!

Jza

So - the bottom line is what??

Should i be swapping the OLD eibachs for the new ones or not???

I am intrigued by your comments below

Are you saying that the car will be better with a lower ride height at the front than given with our springs? What isn't controlled about the rate of our rear springs?

The reason I ask is that I think we tried this spec and found that the 32N/mm front springs gave some unpleasant effects like too much understeer, spoilt the ride and was generally not as good as the springs we did choose, predominantly as the car rode on (or too close to)the bumpstops.

The rear springs appear to be the same as ours. Funny that!!

The proof of this will be in the driving!

I have not attempted to compare the Eibachs with the Prodrive springs, but just the new Eibachs with the old Eibachs. Given Trousers comments on the springs this will result in the fronts being softer and the rears harder.

Softer front and stiffer rear springs will (as you know) result in less understeer - which sounds an improvement over the standard springs.

I agree that it is interesting that the design of the rear springs has changed from "progressive" to "linear". As you say, this looks suspiciously similar to the Prodrive ones ....

Will the fronts be too low and too soft? I don't know (and we'll only see when driving them on a bumpy surface) - certainly hitting the bump-stops would be a bad idea. From a styling point of view it will look good. Perhaps TSL will be providing lowered bump-stops next.

All in all, it is probably beyond my driving skills to tell the difference.

The use of stiffer springs to control the unsprung weight (as opposed to stiffer dampers) is not the ideal way to go. It is also interesting to note that the new front rates are now significantly less than the "Sports" option from Subaru, and much closer to the standard.

Mike - do you fancy clarifying what the rates of the Prodrive springs are?

Duncan

Edited to clarify my reasoning!

Trouser,

So do these spring fit the STi7 ??? is that the springs are the same but struts inverted???
Tony

BugEyed

They will physically fit as the spring seats are similar. However, they are not suitable rates.

If you see the exchange above between Mike Woods and myself, we have some questions over the rates on the new Eibach front springs when fitted to the WRX. Couple this to the extra weight (at the front ) of the STi, and you are likely to hit the bumpstops.

I suggest that you wait for Trouser to sort some decent springs for the STi (be sure that he will) before changing. Your frustrated - my WRX is still on its original springs after 8 months as I still not happy with any of the options (apart from the Ledas, but I'm also tight ). Perhaps Mike would like to give you a timescale for the Prodrive offerring for the STi.

the Subaru Sport suspension uses a different damper so they can probably get away with using a stiffer spring.

The relative benefits and other wise of stiffer springs and lower ride heights can get a little confused when you get too close to the bumpstops. It's quite conceivable that a softer front spring will give more understeer if it allows that car to roll or dive onto the bumpstop too early. If this is happening you have 2 options: either go stiffer and stop the car rolling so much but this normally hurts ride quality etc and causes understeer in low grip situations; or raise the ride height a little which allows more wheel travel but may give more body roll.

As an example a spring that is 10mm lower than the one we supply for the front of the WRX would need to be something like 50% stiffer to stop the car touching the bumpstops with the same load.

That's why we picked this ride height and spring rate.



Tony

Let me answer your question if I may. All the Impreza springs will fit the STi but as the car is heavier they will inevitably reduce the ride height also. They will therefore need to be either longer or stiffer or probably a combination of both to work in the same manner.


Mike

BugEyed

Mike

I agree! One small point - the stiffer dampers of the "sports suspension" would in theory allow softer springs for a given ride height and avoid hitting the bump stops - yet they are much stiffer.

Duncan

PS On a personal note - any chance of an answer to my Email regarding the wheels?

ukhuskynox

Hmmm, now you lot have got me thinking....

I'd like to lower my uk300 without losing the ride quality, I sthis possible ??

Andy

That was one of the design briefs of our spring kit when used in conjunction with the 18" wheels as fitted to UK300.

Speak to your Subaru Dealer.

Mike

ukhuskynox

Mike,

Many thanks I will have a chat with them next week.

mutant_matt

So what we need then is a back to back on the new STi with the "Grey" Eibachs, the "Prodrive" Eibachs and the "TSL" Eibachs......

Trouser, if you want someone to carry this out for you, I'd be more than willing to help out ( - but someone would have to supply the STi ( ))

Seriously though, you are going to do a back to back test arn't you and post the differences?

Matt

Scooby-Duke

Hi Paul,

Fitted ITG this morning, all ok. Early days but already noticeable difference. Let me know how you get on with the new DV next week, OK! I will be interested in one.

Strewth thank god there's photographic evidence I was at TSL yesterday, my missus thought I might have been playing away!
Hee Hee.

Thanks again Iain for the day out.

If the bumpstops in the MY01 are the same as MY00 then it's easy to trim them and you can get an extra inch of travel.

You can even do this on car. Jack up car move shock sleeve, trim bottom 1 or 2 coils using stanley knife.

If you want to check whether your car is REALLY hitting the bump stops instead of speculating, you can use wire ties. Again, jack up car, move shock sleeve, tie on wire tie at the bottom so that it will sit in position should you slide it up or down. Make sure bumpstop is slid up to top. Go for vigorous drive, jack up and mode sleeve and see if wire tie ends up flush with bumpstop. Easy :-)

David

Many thanks a little wiser now My dealer is fitting them today prodrive Eibachs I think

Has anyone got any photos of their STi's with the new springs and the lower ride height?
