Just had the Koni Sport installed. I can feel the ride quality has improved. I have them set at the "soft" to experiment initially. I may adjust them later. By the way, the installer is a Pro Charger dealer. He told me it would cost about 9K installed.

 

You can save a grand if you do it yourself. That's what i did.

 

It was fun too.

I accidentally left my rears on full hard after an autox event, but adjusted the front to full soft. Man that was a miserable ride back home. And there were speed bumps. Have fun with the setup

 

Now that's funny!

 

The installation was only $375 including an alignment.

 

Sorry. I was talking about the Procharger.

 

I also installed KONI Sports with my stock springs. I had them out on a "test and tune" autoX course a week ago and I really like the way the car handles with them (I also have the stiffer FRPP front and rear sway bars). I got about 30 runs in two days, so I was able to make a few runs and then adjust the KONIs to get them where I liked them for the "autoX course." I usually drive them on full soft for everyday driving - which is still much tighter then the stock suspension. Below is a track video......
