koni yellows, tokico illuminas, and kyb agx's are all externally adjustable.

To adjust the illuminas, all u have to do is turn a knob at the top of the shock, it sticks out above the bumpstop, there are 5 settings, 1 being softest, and 5 being firmest.


To adjust the kyb agx's, there are two ways to adjust them. first u can turn a knob located on the body of the shock(that small black circle on the left side of the shock)
or you can use a screwdriver and turn the knob at the top of the shock just like the illuminas. the kyb agx's are 8 way adjustable(i believe).

as for the koni yellows, it comes w/knobs like asiandoood showed u, the knobs are detatchable, i just keep mine in my glovebox. so whenever i need to adjust them, i pop open my hood/trunk and place the knobs on top of the bumpstop and turn it, counter-clockwise makes it firmer, and clockwise is softer, and take the knobs off again.

thanx for the pic doood :chuckles:

just incase ur curious on prices:

koni yellows-usually run around 500 a set, but they are well worth the money, especially if your car is excessively low and u don't want to buy a true coilover system.

tokico illumnas-ive heard prices from 350-450, they are good shocks also, but most people say they are a grade below koni, but on my friend's TL they have an awesome ride.

kyb agx-usually around 350. a really good value. ive heard nothing but good things about them.
