I put 2 of these on the front with the stock springs. Car rides great now, but here are the steps to install these so you can decide if it's worth it for you: -Remove wheels -unbolt brake line and speed sensors from strut -remove tie rods -remove 2 main strut bolts -pop hood and remove the 3 strut mounting bolts -pull out strut from car -use spring compressors on the springs -remove bolt holding strut together -pull out strut from the springs -drill a hole in the center of the top of the strut housing using 1/4 inch or smaller drill bit -drain strut fluid -mark a spot to cut the strut, 40mm from the bottom of the strut housing (instructions say subtract 6mm from the length of koni yellow bottoms to the portuding bumps on it which is 46mm in this case) -use tape to wrap around the strut on your mark to use as a cutting guide -cut off the strut housing with a saw on your marked spot -pull out oem damper -file down the edges on your cut -use 1/2 inch drill bit to widen the hole on top where you drained the fluid -insert koni yellow into your modified strut housing -use provided bolt in packaging and put through 1/2 inch hole on top and thread into koni -use ratchet to thread bolt to pull the koni all the way into place -remove the bolt and re thread it in the same spot with the provided crush washers -re install into your springs and put back in car And voila youre done. 12 hours later and 3 trips to auto zone and you should be finished. Maybe consider buying a fully assembled strut if that sounds like too much.

Paired this with the Eibach prokit. I have them adjusted about 3/4s to full firm. Ride quality is great. My car is a dd and it's very comfortable. It's perfect for how I want it. Props to kseriesparts for exceptional service and fast shipping. I'll definitely be ordering from here again.......well I already have. Lol. Thanks for everything guys.

So I really like the way these feel, I had stock suspension on eibach sportlines and as soon as I installed them I blew ny stock shocks. The ride was terrible and made a whole lot of unwanted noises. As soon as I installed these, all the noises were gone and the ride felt great! The only downside is like everyone else says, the instructions are poorly written and the modification to your stock assembly is kinda nerve racking because if you mess up, you will ruin your stock set up and the konis won't fit. But don't let that stop you from getting these, they are great shocks. Koni would make a lot more cash if they sold these specifically for the rsx. I believe many ppl turn away from these due to the hard install.

I gone through the entire range of adjustments trying to find a setting for rough roads and I'm not successful. Its quite a rough ride on bumpy roads, compression damping pretty harsh and makes braking difficult.

I love my Koni Yellows, they are a terrific ride for my daily commute, where the roads are not exactly smooth. Paired with eibach springs, the ride is smooth enough to be usable and practical, while retaining good handling for the twisties.
