Hi,
does anyone know whta the spring rates are on the H&R coilover kit designed specifically for the nurburgring.
Cheers
Nurburgring Spring rates

I dont have the answer but if you contact Marc at TTE in Kelberg (just down the road from the ring) then he has a deal with the H&R factory on the kit you want. I have it on mine, havent tried it yet, car still in progress. It's hard at the front and soft at the back.
If I see Marc I will ask him for the spring rates for you.

I am running 350lbs fron and 560 rear and that is too soft for a mostly track driven car.
Have spoken to some guy's at the Ring and they are running up to 1000lbs at the rear.........
But it all depends on fast your are going. I year ago my springs seemed to be perfect, but now sheeding sec's of the lap time I can feel that they start to limit my driving.
I would not recommend just to throw on what everybody else is having, grow with the car and learn.

can you please explain in more detail. I don't think a E30 with harder front springs than rear would handle very well. Usually a 200lbs difference
between front and rear works quote good as a starting point
are you 100% sure about the rear spring rate?89pgy wrote:i've got the ring kit on my M3 fonts are 674lbs plus helper spring of 140lbs and rears are 620lbs but are still a stand alone spring and not a full coil over. Been on my car for 2 years now luv them to death.
As you know the ring is not a smooth circuit. If you run rock hard suspension the car will be very jittery and spend more of its time with wheels in the air than on the tarmac. As the driven wheels are the rear wheels it's more important that there is some compliance there, ie softer springs.
Before I purchased my H&R set up I checked with loads of the locals, including the guy who builds Christine Pulvers race cars. A good few suggested the H&R kit and recommended I get them through Marc at TTE as he has a package made specific for ring E30's direct from the H&R factory.
I do not know the exact spring rates but there is a noticeable difference between the front and rear. As you said different set ups will suit different drivers. When my car is complete I will try it and see how it feels.

Stock springs with Koni shocks, uprated springs with Bilsteins, Springs stiffer with the same Bilsteins.
Don't confuse stiff springs with stiff shocks. (not saying they are not related to each other). You can run fairly soft springs with too stiff shocks and the car will feel bumpy because it can not follow the road.
You need a certain spring rate to stop the car rolling. As faster you get, as more weight transfer will happen.
As I said before, it all changes with the laptimes. Whatever seems to be to hard it the first place, might suddenly feel to soft after you knocked a minute of your lap time.
Yes the Ring is bumpy, but (not talking about myself here) if you come down to 8:00 mins, you will need stiff springs. And they will work.
But using the same setup for somebody who is doing 10:00mins, the car might not feel right and bumpy.
And don't forget about the tyres, R-compounds generate a lot of corner forces.
It is good to speak to somebody with Ring experience when buying a setup, but not everything works for everybody.
Try to find out what spring rates you have been sold, I would be very surprised if the fronts are stiffer than rears. If in doubt, you can send springs to FAULKNERSPRINGS to get them Dyno tested.
It's your perogative on how you approach that subject. I like to know exactly what have and exactly what is changed to get an understanding what is happening.
I have driven with a guy on the Ring with Grp N springs and the car felt very planted. I am tempted t get these springs because I have a set of matching Grp N shock already. the spring rates are 685 front and 1025 rear
wonder how this will feel on the drive over to the ring on Belgian roads

Agree with Gary on harder on the front and softer at the rear for any track not just the ring.UweM3 wrote:??northloop wrote:At the ring your car needs to be harder at the front than at the back due to the lumps and bumps.

I'm running 500lbs front and 300lbs rear, its a bit soft so am looking at upping it to 550lbs and 325lbs
A harder rear would make for some "interesting" handling IMO, you sure you've not got your front and rear figures mixed up???
Not heard of any of the race cars in khumo, PBMW, or Pre93 running harder rear than front, except for 1 guy who when he went more along the lines I said above moved from midfield to front of the field.
I was talking about rear OEM spring location, not coil overs. That's probably the confusion.JimmyC wrote:Agree with Gary on harder on the front and softer at the rear for any track not just the ring.UweM3 wrote:??northloop wrote:At the ring your car needs to be harder at the front than at the back due to the lumps and bumps.

thread started off with H&R's and they are not rear coilover.
If you look in the BMW Grp N catalogue, the rears do not even start below 180N, but fronts are coming from 120N upwards.
As above, ensure you compare like with like. Ground Control recommended 600 front 800 rear, on the original seat. I changed the rears to 1000lbs to make the back move as I wanted it.
This year I softened the front to 550, which I am pretty sure is ideal. Changing to a coil over (Gaz) rendered previous data useless, but the 300lbs on the damper mount work well.
Must get around to selling my old set up!

[quote="JimmyC] My bad, thought the H&R's were coilovers

good we got that clarified. Was already starting to worry about my setup
after thinking about all the possible options, I am leaning more and more towards GAZ . Just need to sell thoose Grp N billies to create some funds.

Uwe sorry don't come on here that often. Yes those spring rates are correct, got them from h&r as we needed to be able to quote to customers.Iknow front is harder than rear but this only happens on the ring kit[dont ask me why] Next time we meet your wecome to a few laps to see what you think.
