    Default 8kgmm front, 6 kgmm rear springs too stiff for shocks

    Hey guys, I'm running AJPS 8kg front springs and 6kg rears with (new) KYB excel G shocks and the car is bouncy as. The dampers arnt good enough to controll the springs. So I have 2 options I guess:
    Softer springs- would these shocks control 6kg fronts and 4.5kg rears?
    Or better shocks, which I assume will cost a lot more than a new set of springs, and prehaps the 8kg/6kg combo is too stiff for street use anyways.

    i have 6's in the back of my keto with kyb's its still bumpy it all really comes down to how bad the roads are where u drive, but alot of people do recommend 6 in the front n 4.5 in the back for daily use

    I've only driven it up and down the driveway at this point! Lol, but over the bump into the shed it bounces and if you jounce the car by hand its like the shocks are stuffed... It keeps shaking for a bit

    Bloody hell i thought i would never see people on here admitting that 8/6kg is too heavy a spring rate for the street. Was only a little while ago that AE86 owners would scream blue murder if you ran less.

    I run the same setup as yours, and in no way does my girl 'bounce'. Double check and tighten everything, and like sundee86 said, take it for a good drive!
