Go here to order. I placed my order and had the springs at my door in a week. I am located in Texas. Shipping was $88 so it was right at $350 shipped. Excellent customer service.

Kind regards,

Chris.

What is the drop on the euro springs?

0.8" front, 0.2" rear.

Yours looks higher than the Supreme Power car. Is that solely because their car has 20s or is it the lighting?

Keep in mind you're shipping a large box with springs in it from Belgium.

At any rate - the springs shipped were $350ish. You could go buy them from **********s as well, but you're paying $349 + shipping. So, it's actually cheaper to get them overseas.

Just food for thought.

Thank you for the kind words and for choosing Supreme!

The ride looks excellent. If you'd like us to send you the photos please PM me your email.

It's probably mostly lighting. Here's EndBoss's M4 with the stocks and Eibachs.

Wow thar looks great! Thanks for sharing. I wonder if they'll be as firm as the Swift springs.

No, these are progressive springs and will be softer and less firm and controlled than the linear swifts.

Different feel. Softer ride on impact, likely less suspension control though.

Both are compromised, but on different aspects of suspension compliance.

Thanks, dude. You still going with the Swifts even if the drop is more aggressive as a result?

the front drop doesn't really seem to be more aggressive.

In my experience, eibach springs are too soft which results in a lack of suspension control over undulations and I don't like progressive springs on a car designed around linear springs.

I also don't like that the eibachs drop much more in the front than the rear. this affects weight distribution, and focuses even more weight on the front of the car, which is already too front biased.

I am concerned about the potential ride quality of the swifts because of the amount of drop, but I am willing to try provided the final numbers show a drop that isn't too low.

According to the picture posted in the Swift Spring thread, the Swift also seem to have variable rates. What makes you believe they are linear?

See my post above. I doubt that the Swift have a linear rate.

Lowering the front more than the rear will only change front-to-rear weight distribution by a negligible amount not even worth mentioning. Having a bottle of water in the cup holder may have more impact on the weight distribution .

I'm pretty sure Swift told him this in an e-mail.

Look at the picture I posted, these are clearly not linear.

Maybe Swift offer different options, with some linear and others progressive ?

I see that I was just letting you know why KP said that.

because, as I already stated in the other thread in a reply directly to you, they told me in an email, and re-confirmed when I asked them to clarify

now, if you think they are lying then...?

and in the same thread we discussed the fact that those fronts appear linear, while the rears appear progressive. those are also not the final products, as they aren't even released yet.

I wouldn't say lying; marketing talk maybe

I'll believe they are linear when I see a picture of a linear spring

I remember our conversation in the other thread very well. I just wanted other readers to see the counterpoint in this thread also.

Aha, that makes sense. Thanks for posting the link .

Interesting that, based on the pictures, their "Sport" line has fixed rates while their track oriented "Sports Spec-R" have variable rates.
