Koni Yellow Sport CRX Installation

Koni Yellow Sport Installation

10/2/2016

After months of technical issues and back and forth with Koni, we were finally at the home stretch of the installation. Time to get these onto our CRX!

Before proceeding, it's important to get the correct torque specs for each bolt. Here are the specs for both the front and rear struts.

Front
14mm Shock Tower Nuts: 29lb-ft
17mm Fork Bolt: 32lb-ft
17mm Control Arm Bolt: 47lb-ft

Rear
14mm Shock Tower Nuts: 29lb-ft
14mm Upper Arm Bolt: 40lb-ft
17mm Control Arm Bolt: 40lb-ft

Front Installation

The brake brackets are labeled "L" for left (driver side) and "R" for right (passenger side). These allow the brake lines to fit properly during reinstallation.

Make sure the bracket sits flush with the fork. This will allow the fork bolt to easily slide through.

Front installation complete! Looks great behind our brand new set of Centric Rotors.

Rear Installation

The rear struts are a lot easier to install compared to the fronts. Just two shock tower bolts up top, two upper arm bolts, and a control arm bolt at the bottom.

Make sure to torque the control arm bolt to 40lb-ft.

Rears all done!

The Koni Yellows allow us to adjust the rebound firmness of each shock. This is normally suited for aftermarket springs with stiffer rates but since we've decided to reuse our OEM springs, we'll be running our Koni's at full soft.

Nancy finally has a new set of struts. We'll take a bunch of photos and provide driving impressions for next week's post. Stay tuned!

Nice blog!

I've owned a '90 CRX Si since 1991. It had less than 10k miles on it at the time. It currently has 170k.

I've had Koni Sports on it since about 1999 or so, always with the stock wheels and tire size.

The first set of springs I used with these shocks were old 1st generation Neuspeed Sport Lower Springs. I believe these are different than the green ones that Neuspeed eventually began to offer.

I swapped those springs out for Eibach Pro Kits after a few years and used those for a while. I then put the the stock OEM springs back in for a time.

For the last ten years, I've been back on those Neuspeed Sport springs.

I've been using those same Koni Sports during all those spring swaps and am still using them to this day. They still work fine.

By far, the best ride quality I've had in the 26 years of driving this car was the stock springs with the Konis set to full soft.

The Eibach Pro Kits were the worst. Front rate was too high and rear too soft resulting in understeer and pitching in the ride.

The Neuspeeds are pretty comfortable with the Konis on full soft, but just slightly under damped maybe. When I turn up the rebound damping slightly to compensate, the ride quality diminishes. However, this set produces the best compromise of ride quality and handling response.

I was 21 when I bought the car. Now that I'm 47, I think I might put the OEM springs back in...AGAIN...just to get the super ride quality back.

One thing about the Konis is that I had to use the lowest perch setting on the rears to approximate the perch location on the stock shocks. This is regardless of what springs I was using at any given time. The part# is correct so I don't know what that's all about...
