Shocks and springs.....

Hi folks

I'll decide whether or not to buy the bargain eBay KYB AGX shocks tomorrow night - at the current exchange rate they'll set me back for less than $500 a set.

But before I decide there's a few things I need to consider

1. I like the fact that it's adjustable as I find the stock Bilsteins a bit jolty for city driving - but I'm also considering a return to track days this year and that I can set it at full sik level - is the range of adjustability of the AGXs suitable?

Seeing as I don't have the tools (namely a spring compressor) or the experience I think I'll leave it to professional hands especially when a stuff-up might mean a catastrophic effect on the handling or worse still, putting the car out of action. Now Mania are the first people that came to mind (I could, of course, just pop down to Midas down the road) - and seeing as the old shocks and springs are coming out anyway, I might as well get a set of new springs while they're at it. Which brings me to the next question:

2. I find the car leaning a bit at times during hard cornering (as cars do), and I kind of like the idea of the progressive King springs, but I don't like to lower the car for practical reasons (enough scrapes as it is), how far will the progressive rate King springs drop the car, and more importantly...

3. Do they work well with KYB AGX shocks?

Feedback much welcomed, thanks in advance as always....

Cheers

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.

mmm the Eibach's are pretty exxy at double the price, are they that much better than whitelines/kings?

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.

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.

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

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.
