Eibach Coilovers: The Pro Street-S

[Koala Yummies]

They are here!

These are the Eibach coilover suspension kit for the CR-Z, the Pro Street-S.

When Honda released the CR-Z, they gave away a few models to aftermarket parts manufacturers and tuners, and Eibach was one of the companies that received a CR-Z to develop parts for.

I was really excited to hear they were going to develop a coilover kit for the CR-Z. I have toured Eibach's headquarters and US manufacturing base in Corona several times, and their engineering, manufacturing and quality control are top notch.

I owned an Integra Type R before the CR-Z, and have personal (HPDE/racetrack) experience with many different manufacturer's coilover products, from Mugen, Koni/Ground Control and PIC, and hands on experience with other major brands (Tein, Zeal, Buddy Club).

When I opened the box for the Eibach coilovers, I was immediately impressed with the amazing quality throughout. I can't wait to install them.

I'll just get on to a few of the specifications, and to the photos:

Monotube shock absorbers, rebuildable here in the USA. The shaft of the shock is very beefy.
The spring rates stock are 275lbs/in front and rear. They use the ERS (Eibach Race Springs) so you can choose any spring rate you want.
The fronts and rears both have helper springs, with a metal collar to keep the two springs aligned, to prevent the spring from becoming un-seated should the suspension become completely unloaded.
They have been tested out on the racetrack several times, and they played around a lot with the spring rates and damper rates to find the best overall ride quality and performance balance (I was present when they did a lot of the testing at Buttonwillow Raceway, so I can attest to their extensive real-world testing).

Thanks so much Tony, Phong and everyone at Eibach!

I should be installing them in a few weeks and will take more photos and give plenty of feedback.

These look great, can't wait for a review. How much did they run you? I know the msrp is around 1800$

PM me I can hook you guys up

Glad you finally got a set, Koala!

Also note (2nd picture) that the upper hole on the front shock steering knuckle mount is elongated allowing you to adjust the camber. Nice .

And those spring rates work out to about 4.9 kg/mm which is seems to be a pretty good rate for both street and track.

I'm assuming the dampers are adjustable (it doesn't say)?

(Still like my HiperMax IIIs but these might be a good alternative.)

[Jackson]

The dampers are not adjustable. We will make an adjustable version for our CR-Z in the very near future. If there is a market for these we will offer them to the CR-Z community as well.

If you want to search around for best price the kit part number is Eibach 4085.711.

Damn you paid $1895+ for these bad boys?!

Getting ready to install, hopefully this week, so I went through and made sure I had all the nuts and bolts ready to go. This way it's a plug-and-play affair and won't have to disassemble the stock front shocks for the bearing and nut that is required.

The stock bearing and nut required from the OEM suspension:


And new bolts and bushings elsewhere:

Looking forward to the install and of course some pics/impressions and how you have em set up..
