ok right now my 93 hatch is lowered on koni yellows and ground control with 350F and 280R i believe. this setup just seems to soft for me. i also got a rear asr subframe with 24mm swaybar and itr front sway bar. do you think that the koni will be able to handle 12k rate up front and 14k rates in the rear? i know this is more on the stiff side but whats the highest rates koni shocks can handle???

 

those are 670lb/in and 780lb/in. Thats very stiff for the street. It may be too high for the Konis as well. I think around 500-600lb/in is about the highest without problems.

 

OTS Koni yellows are only rated to 550lbs, you will lose your warranty with anything stiffer.

 

koni revalves for free if i'm not mistaken.

 

If being used properly ^
