Just curious if anybody knows the spring rates for the ITR specific H&R Sport springs. Thinking about pairing these up with some Bilstein Sport shocks and wanted to know how these springs compared to the stockers! I'm currently running the Tein S-Tech's and wouldn't mind something a bit stiffer!

Thanks for the help!

How are those Tein S-Tech spring compared to stock?

 

I was wondering the same thing. I even tried calling H&R and the only thing they could tell me is that they are 20 or 30% stiffer than stock, but they couldn't tell me exact rates. There are several members on this board that are running these springs on stock shocks and are happy with them. I think H-Pimp is running that setup, maybe he knows?

 

I've got the numbers at home somewhere, gotta dig them out.
Dont quote me on this but I thought it was like 50lb front 25 rear stiffer.

I'll try and find them later.
I know of several ITR's 2000/2001 model year using H&R's on stock shocks for over 6mo to 1 year now without any probs.
(put through the paces at events too, ... not just puttering around town)

 

Sinitron,

Let me know if you do find the exact numbers...although 50/25 is about what I expected.

Thanks,
Chris

 

i seem to remember hearing that they were 276/276.

 

well, i was interested in these springs so i called H&R USA just now, and found out that no one, even at H&R knows what the spring rates are. apparently the headquarters in germany doesn't release the spring rate information. all she could tell me was this:

part # 29502 (ITR-specific)
-front is linear, rear is progressive
-both front and rear are 25-30% stiffer than stock

not much of a help, but that makes the spring rates, theoretically:

-front: ~315lb/in
-rear: ~225 - ~315lb/in

1.5" drop in front, 1.3" drop in rear.

That's still pretty soft (~315ish). I doubt that you would notice a SIGNIFICANT change in handling, other than the lower CG.

 

H&R does not release spring rate info. I guess they think its privileged information. PYTypeR408 (Chris) just got an H&R/Koni sport setup. Ask him what he thinks. Good thing about the Konis is that lower perch height is adjustable. Good luck.

 

well, i'm currently running a GC/koni yellow setup, and while i like it, i'm leaning towards getting some ITR-specific bilsteins for the GCs. i wanted to try out the ITR-specific H&R sport springs, but i hate progressive rear springs . . .

david, have those recaro SRDs come in yet? LOL...

Peter- I am told on the 8th to expect them.

 

yay! wait - the 8th of september?

 

I am running that set up, but I dont know the specific rates. I do know that with 18 inch wheels and the H&R sports the car handles really good as opposed to stock height and 18's which totally sucked.

With the stock rims the handling is out of this world. I'm also planning on installing a JDM rear sway bar in the next two weeks so I'll let you know the difference after it's in. Later.

 

I don't think I would buy springs from a company that does not release spring rate information. It is essentially the defining characteristic of a spring. Not providing this information is equivalent to a car manufacturer not releasing horsepower information for its cars.

 

I'm sure they release info for their race springs. This is a low end consumer product were talking about here. What's the big deal?

 

The US H&R office does not release spring rates. I honestly don't think that they know them. I have heard that the german office will give you the rates, but I haven't cared enough to waste the $$ calling.

 

discriminating consumers want to know!

yeah, i know, it's a $200 set of springs. i guess '25-30% stiffer than stock' is going to have to do.

their 'race' springs are not like eibach ERS springs. just shorter, stiffer versions of their sport springs.

 

Race springs are higher rates and linear in the rear. They are a good bit stiffer than Sports, I've driven ITRs with the Race springs on sebring and @ autox.

 

Big Phat R> I'm sure they release info for their race springs. This is a low end consumer product were talking about here. What's the big deal?

So you are buying a product, the most important characteristic of which is the spring rate, and the company you are buying them from will not give you this information. If I were to buy springs from H&R, I would regard this as a big deal.

 

I bought H&R's based on previous experience with them. My Sports+Bilstein combo (GS-R) works fine. The car wins DSP, does fine on lapping days and isn't too harsh on the street. I just wish it wasn't so low, that's my only complaint with the Sports...

 

So then don't buy from them I guess.
