Shocks and springs.....

Have you thought of the Eibach spring set?

Rob just had them fitted to his NA and seems to be impressed with them

What rjastra said. After cruising around the snowy mountains on them last weekend they ride much smoother than the stock springs but still manage to stop the lurching in the corners. Very impressive. The only problem is that they lower the car about 20mm which might make them unsuitable for your application.

Does anyone know if Eibach make standard height springs as well? They'd go well on the SP I recon.

After speak with people at the Natmeet trackday, all I ever thought about progressive springs was dismissed. I heard stories of them being wallowie and vauge on the track. It was accounted for by the softer initial compression, giving less resistance to roll than even the stock spring.

If I were in the market I'd be looking a the Eibach or Whiteline (I thing those aren't progressive).

Please don't cross-post. this area is for the rabble, other forums are better for the tech discussions.

You get what you pay for. The Eibachs are a better quality product with more R&D involved, though it's up to the buy to determine whether they are twice as good.

mate, it's a coiled bit of steel. How much R&D can there be?
I reckon the Eibachs are too low given their (mild) spring rate.

So the properties of this "coiled bit of steel", hardness, torsional strength, diameter, coil seperation, colour (ok maybe not colour:?) etc etc are guessed? Ok, you make one.

Aren't some cold and/or hot wound? I've heard this affects the quality of some.

Slugoid wrote:Kings, Eibach, Whiteline....all the same imo. What makes Eibach more expensive is that it's fully imported and it's made in Germany (i think). Kings have a big aussie base and Whiteline is an Australian company, so that's why they are cheap. Not because they have less R&D than Eibach.

exactly. I was being sarcastic about the R&D thing - I could design a spring with my eyes closed. (I'm a mech engineer and have designed plenty of springs). As I elaborated, I think the Eibach's are pretty poorly engineered personally...

Since you are in Sydney why not go to KMAC at Taren Point?

Get them to make the springs to your spec and have them fitted.

They can custom build to your ride height and spring rate.

KMAC have moved to Princes Hwy Rockdale

I got a quote from KMAC a couple of months ago and it was very competitive with the price of kings, etc. KMAC also asserts that their springs will not sag like some others, they have a special furnace that makes for better spring steel.

Can't remember what the price was as I am not at home right now and don't have the emails from them.

I do remember that custom, fully adjustable sway bars were $325 each.

Correcting my last with a cutting from the KMAC email.

We use the very highest chromium grade spring steel.

K-Mac is also the only Australian manufacturer to use
\"State of the Art\" electric resistance heating for
maximum torsional effectiveness and prolonged life.

Springs (any height required) are $330 set 4 incl GST

Front Anti Sway Bar (24mm) is $180.
Rear (14mm or 16mm ) is $165.

$330 for all 4 springs is very good. A set of Eibachs are on special at a known supplier for just under $400, and that is also a good price.
