KYB vs Koni

[deb0704us]

Researching new struts. Guys here recommended KYB. Obviously KYB is less expensive than Koni. But what is this concern about the pogo effect all about? KYB tells you right up front it won't help pogo effect.

About KYB "If you're looking for something that's going to help with the pogo effect caused by aftermarket performance springs, these do not have the dampening characteristics to resolve that issue. They are great factory replacements to worn struts but the only thing that's going to help with the pogo effect caused by aftermarket performance springs is a performance strut with dampening characteristics matched to the performance springs. The only thing currently available for this is the Koni Sport Adjustable Strut package offered elsewhere in the suspensions category of the store."

About Koni...they are adjustable, but how? Knobs under the car? Isn't this inconvenient? Especially in winter?

Koni:"If you've upgraded your springs to Eibach or other aftermarket springs, you're all too familiar with the pogo effect. Koni serves sporting drivers with a carefully designed range of sport shock absorbers. This line focuses on exceptional road-holding and handling properties, combined with an acceptable level of comfort. Its characteristics include responsive steering, improved body control and limited body movements when braking and accelerating, all resulting in a direct feel and excellent wheel-road contact. Our Koni Sport dampers are externally adjustable by means of a knob, so they need not be disassembled from the car. The fine-tuning of the damping forces to personal driving style and to different driving conditions is therefore not more than a matter of seconds. The best of fine-tuning technology straight from the world of Formula 1 racing. The hunt for upgraded struts for your car is over. At this price there's no reason to look any further. "

Have you installed new springs? If not, go with the KYB's. KYB's are pretty much the best for stock setup. You won't get pogo effect by simply installing new KYB's with the stock springs.

No pogo with the KYBs and stock springs and it only happens with aftermarket lowering springs & KYBs.

Those must be the ones from PFYC and they are very spendy and not really worth it since GM also came out with a complete strut kit...What PFYC did was take a Ford Taurus strut housing and modified it so that it would fit our GPs with Koni .

If your looking for a great ride and a little lower stance id look into the GMPP (GM Performance Parts) konis part # 12498354
