This thread was created to track all the coilover options on the market for the CRZ. It is a work in progress and I hope someone finds it helpful. I wanted a quick way to compare specs, approximate prices and to collect reviews from owners. This thread was intended to be a good starting point for research not an Encyclopedia. If you guys think this is useful I'll continue to update this thread when new items are released.

If any of you own any of these coilovers, please post impressions and I will add them to the first post. Also if anyone notices a typo or other misinformation please let me know. All preliminary information gathered from pages of different vendors here or from manufacturer videos etc.

Interesting things:

1 - Most coilovers here have stiffer front rates compared to the rear but a few are stiffer out back. Im not sure why that is.

2 - Even some of the pricey coilovers require you to re-use stock top mounts.

3- Most common spring rate is about 6kg/m in the front and 4-5 kg/m in the rear. This may be a good starting point for comparison between brands.

4-Price of OEM Top Mounts: see post below


If I forgot anything or you have information to add, post up!

anytime you make drastic changes to ride height, you want to consider an alignment. even if you car still tracks straight, the toe in/out changes drastically and can affect your mileage and handling characteristics.

also, for those in colder climates or anywhere subject to more moisture and salt. you want to check and clean the threads periodically to prevent seizing. many new coilovers have a teflon coating to prevent this, but i still do this out of habit, and to make sure no settings have changed.

if you're not looking for a jarring hard ride, look into the RS*R coilovers. it's their sports-i line which is mid-way between a street and weekend track coilover. very OE quality. they service them in the US. i've had them for a year now and love them.

near stock damping (soft) to rock hard for the track if you wish, 36-way. independent ride height adjustability within the range you specified. softer spring than most competitors so it's not as harsh for a street setup. but for full track setup i'd opt for stiffer springs or go tein monoflex which is about the same amount of money.

they also have lowering springs.

link here for both

the one downside, if there's any. the front shock has a short stroke. if you have particularly bad roads, you can bottom out on the bumpstops if you run a softer damper setting than RS-R recommends (re-uses stock bumpstops so they're nice and cushy if you hit them). you'll only notice if you hit a massive pothole or hit large speed bumps. not sure if other coilovers run a similar setup.

Yes, I got the HPD suspension specifically because they offered a relatively small drop. Plus a bunch of other reasons.

I love the suspension during the spring, summer, and fall. It greatly improves the stability of the car and keep your wheels planted in the corners. I think HPD did a fantastic job of building a sport-tuned system that may be lived with in a daily driver.

That said, the stiffness was punishing this winter. With the extreme weather we got in New England some of my local roads have turned into mogul fields. My head has bounced off the roof liner more than a few times.
