I just got off of the phone with Eibach and was a little disappointed when I hung up. According to a rep about a week ago, a pro-kit was supposed to be available by the end of the year. I have been researching and I was prepared to order the kit when I called Eibach again and was told that the rep had made a mistake and the springs will not be ready for a few months. So looks like I have to wait. BE WARNED, the springs for the 350Z DO NOT DO NOT DO NOT work for the Coupe.

 

Damn.... I was looking to get some springs really soon also. I wonder why my wheel guy said that springs are out for my coupe already. Is he trying to use the Sedans springs on the coupe? Will that even work?

 

Why would you just want to change the springs? Especially to Eibach? In most cases changing the springs makes the ride worse, doesn't improve handling, and increases tire wear. ONLY when you have a matched set of springs/struts that fall within suspension tolerances can you hope to achieve positive results.

Unless you just want to be a "poser" and have your car lowered for "looks", I'd advise against it.

And Pahlease don't give me any of this B.S. that the Eibach sales person told you that their springs will improve your car, what do you expect them to say? Ask them about Boxster springs sometime and I bet they give you the same line, and I can show you hard evidence that Eibach and H&R springs on a Boxster both DECREASE the performance of the car. (They do make it a low-rider though...)

 

Eibach makes springs for Porsches? Who in their right mind would think a $400 set of springs would make their Porsche handle better?

I agree with not changing the springs to Eibachs. Wait for a full coilover suspension to come out.

KenDude, Wow... I did not know that this was a touchy subject... Poser? OK... I just want a car that looks nice and I do not want to loose on the ride quality.. Does that make me a poser? So by getting the right springs/struts I'll be the real deal? I'm not on the track everyday, but I don't want a harsh ride. Let me know what kind of set up you suggest for ride quality and about an 1 inch lowering height.

Thanks,
Tom

 

The reason Eibach is not releasing the sprinsg yet for the Coupe is because they have noty finished perfecting them. Eibach has made a name for themselves throughout the racing industry and on the streets. The springs Eibach makes are to specific regulations and standards. They are made by Eibach specifically for a certain car. My guy told me that the 350Z springs will fit the COupe but he is totally wrong. I spoke to Eibach and discussed it in detail. The Pro-kit only lowers the car a little over an inch and does not affect the ride quality much if any at all. Only if you slam a car will it really affect the ride quality and I have dropped a car 2 inches and didn't feel much of a difference. On the the coupe and Z and Sedan there is no need for struts or shocks or a camber kit. The springs are all you really need and you will be set.

 

I disagree. Springs is just for looks and will not esult in significant handling improvement. To increase handling you need a properly matched shock an spring. This also allows you to shorten the shock length and increase diameter so that it is operating in it's intended range for better handling and ride at lowered ride heights. With greater piston diamater you also get an upgrade in damper performance to match the higher spring rates which is crucial. Unfortunately Tein will not have a full coil-over setup available till Spring.

I lowered my 94 Mustang GT with genuine Ford springs and nothing else and wished that I never did it. Not only was the ride horribly stiff and bumps jarred you to the bone, but I then had to worry about scraping over everything in the road. The car was lowered about 1.5 in. I would NEVER lower a car again using springs only.

 

What are they going to do about the rear suspension. Correct me if I am wrong but coil overs wont work on the Coupe because the Shock and Spring are in two seperate places, atleast thats what the brochure says.

Haven't actually looked... but I am pretty sure they are two pieces.

rxkeven,

Do you have pics of your coupe with the 19's? If so please post....

 

They will use seperate springs with adjustable perch on the springs with short stroke shock. I have pics of the 350Z kit to make it easier to understand. I'll try to scan them.

Tom,

Didn't mean to say that you were a poser, only that if you simply slap on lower springs on your car, chances are that your ride geometry will not be right, tire wear will increase and handling will get worse. Yes, the gap between the tires and wheel well will decrease, but is it worth it? For me, NO. I want to make sure the ride geometry is actually benefitting from any spring change and that usually requires a shock/strut change as well, and possibly other changes. I don't have a specific recommendation for the G35 yet, but if I find one, I'll post it.

 

Dan,

If you could post pictures I would be interested to see them, how is this going to affect the balance? I want to make sure to avoid excess toe in by dropping the ride height without properly adjusting everything.

BTW - Pictures of my G35 will be coming soon (I have to wait until after christmas to open my digital camera)

Call HKS, They are suppossed to have Hipermax Damper LS's. I believe they are the same as the Z but are valved specifically for the G due to it's extra weight. They will also have Hipermax II's for the Z soon that should cross over. Here the valving should not be an issue because the II's are 30 way adjustable where the LS is set. They both allow ride height changes and include the upper pillow mount. That's what I am waiting for. I had II's on my '95 Supra Turbo an wouldn't run anything else now. Pretty fairly priced when you consider what you are getting (4 dampers, 4 springs, 4 upper mounts) all designed to work together, ride good and improve the handling. Good Luck!

 

What would the price of these Hypermax II's be?
