H&R Race stiffer than IE3???

[MR 325]

Which one is stiffer? Anybody know the rates?

I know we've talked about this before but I couldn't find the thread.

[Danny]

Same exact rates.

[E30Idea]

Same exact rates.

Yep, I called last week to both places.

315 Front
570 Rear

Hope that helps

[MR 325]

Anybody know the amount of drop each spring is supposed to give?

[Danny]

H&R looks better, drop wise.

[Kingb]

I forget the numbers I think. 2.1 and 1.7 I might be wrong though. Like Danny said H&R give a better stance IE3's sit a but low in the rear. But I still have a set in the mail. I had to

[E30Idea]

You are wrong. That is more like my cup kit drop. H&R Race drop is 1.6 front and 1.5 rear.

[smonkbmw]

You are wrong.

he is right. whats published on the site is not exact. i got around a 2" drop on mine while i owned them. the cup kit sits lower because it has a horrible spring rate (read low rate) and yes for late model cars the ie3s sit low in the rear. for proper rake go with the H&Rs (who wants rebadged Eibachs anyways?).

[MR 325]

So H&R Race = lower than IE3?

[Danny]

Yes

[smonkbmw]

are you going to run the wheels in your sig matt? if so i dunno how thats going to work, it might not clear the rears if you go that low...

Sorry to bring this thread back from the dead but what is actually lower IE III or HR race? this thread seamed to contradict itself..

I am lowering a street car only and want a comfy/sporty ride yet have the spring stiff enough to prevent wide wheels from killing my fender lips (17x8.5 17x9.5). I have a set of 10mm from drop hats at my disposal. what will give the best low stance? should i look at a 60/50 setup?

I have coilover on my other e30 and i woudl like the ride less harsh than that

[Erick]

I know this is an old thread but wow:

(who wants rebadged Eibachs anyways?).

Oh I'm sorry, has Eibach not been racing for dozens of years testing their springs continuously in various different motorsports?

So surely no one should bother with GCs then, because those guys live by those springs.

As for the recent question, people argue that the IE3s sit a bit lower in the rear (as posted here)

I personally had both. They look the same to me, although I never ran it on the same chassis/wheel setup. H&R Races on a 318iS with 17s and IE3s on a 325i with 15s.

[Philo]

Rule of thumb, from what i've seen, IE3 for early arches : H&R race for late models. I have H&R race on my late model and love it. A friend has the IE3 on his late model, and the rear is a tad lower, giving more of a level to slight reverse rake look.

The only thing both of these springs lack is about 10-15mm more drop up front. GC plates should take care of it, at least i'm hoping. :up:
