IE stage 3 vs Turner J stock

[Gus]

i have been searching but cant find bugger all......

im looking for a spring to replace my current setup....its just too soft for use at the track. coilovers are out of my price league, so im wanting the stiffest spring i can get. have heard good things bout both springs. its going onto a facelift, so if anyone has pics that would be great..wheels are 205/55R15 basketweaves, shocks are the stock motorsport (the M325i we got over in NZ) bilsteins....they would stay for a while until i went Koni SA's

currently running the stock front sway, motorsport rear (14.5mm), urethane subframe mounts, strut braces front and rear. looking for more stability in high speed corners....i can feel it settling around and its not much fun at 150kmh....i should probably get some offset urethane CAB's too as i had them in my last car and really liked them

cheers for any help/suggestions

J Stocks are fucking stiff, much stiffer than IE Stage 3's.

yeah, what he said


and stage IIIs are perfect for a track car. get them

[Gus]

i was kinda hoping for stiffness

surely they would be better for a track car than the stage 3's? im hoping to keep my current setup (it is my DD after all) but also have something stiff for when i want to go to the track....my worry is that the stage 3's would be too close to my current setup to make a difference

cheers

You can't run any of those springs with stock shocks anyways.

[Gus]

if i got the turners would be getting the matching shock from them as well

don't have stock shocks anyhow

stage 3s not FUH RAZE enough for your daily???


you know they are the spec spring for e30 racing in nasa right? (well, H&R race, close enough)

[Gus]

haha fuh raze ness is awesome....will go with my homemade CF bonnet when i get round to doing it

didnt know that....i really dont know a lot about either spring, as we dont get them over here....and cant compare spring rates to any local springs as the local ones have no idea what their rates are...pretty arse.

the thing i like about the j stocks is that they come as a matching shock/spring package, which i like as im not really experienced enough to tell a over/under damped package (well obviously to some degree but ya know)

if i went the stage 3's i would probably use my bilsteins for a bit, and see how that went....and then maybe look into getting some konis/bilsteins from over here.

just noticed the IE's drop the car a little more.

please keep the comments coming....cheers

You said right there you are keeping the stock shocks. They won't work with either spring. Just because they are made by Bilstein doesn't mean they would work with either of those springs. And even if you got IE's I'd still recommend Konis.

...the HR at 300/500 ish are a bit soft but good overall

I have buddies running H&R race, aka what IE stage 3s are copying, and are happy with them on the track, and they are livable on the street.

J-stocks would be a fucking nightmare on the street I'd think.

[Gus]

the stocks are bilstein sports, been running with lower springs and control rebound fine....regardless ill be changing them out when i can

i dont suppose there is anyway of getting the spring rates of the H&R's or IE's? ive asked IE and they didnt say.

ive got a mate hopefully selling his bilsteins so could steal them and get the IE's

and another q, would GC's on a softish rate (like the 300-400 mark) be the same firmness as a normal spring the same rate? curious, as i dont have much coilover experience

[Marvin_Hecht]

So the stock spring in New Zealand for this M-suspensioned E30 they sell
is a Bilstein Sport? Because for North America I am pretty sure that no model came with Bilsteins...only Boge's. And what your "average Joe" upgrades to is the Bilstein HD's not the Bilsteins Sports.

So...if you do have Bilstein Sports, that is the proper schock for the IE stage 3 or H&R Race.. unless you go with Konis which some people like better.

It is interesting that IE will not reveal their spring rate. Because I thought that IE specifically got their springs from Eibach custom-made for a certain spring rate, and the president of the company himself sits and tests each one that arrives for spring rate, thats what i heard ...if so, why would they not give out the spring rate for the IE stage 3 springs? Unless what I heard was referrring to the Coilover Insertion springs that Ireland Engineering sells, not the IE stage 3....

What are j-stock springrates?

Gus, JUST READ THIS THREAD. It gives a lot of info you could use:

cheers, why can i never find anything when i search!

j stock spring rates according to turner, are 600ish front, 1000ish rear...can see why that would be stiff in the rear

what about the IE stage 3 springs and the turner bilsteins?

ill rephrase what i have have been unclear...the Motorsport 325i (you guys didnt get it, known as the UK sport or whatever) came with kit, LSD, sport seats...basically a 325iS with a body kit. however they made a pre FL version too, and it used bilstein sports (the later ones used boge too). however they are not AS firm as brand new bilstein sports (whether due to age or valving, i dont know) hence i am looking for something stiffer.

another reason i want to change is i have no idea what springs i have...came with previous car. i like the ride height, and they never scrape, but i just want something stiffer

so im thinking now, maybe the IE stage 3's, bilsteins (maybe the TMS ones) and then further down the line a set of IE or TMS sways...fun
