Shock Dyno Testing
All graphs show brand new, off the shelf
front shocks for ’92-00 Civic/’94-01 Integra
About Shock Valving Graphs
• Rebound is above horizontal center line, compression
or bump is below with forces increasing vertically
away from center
• Piston speed is plotted horizontally from zero at left
with speed increasing moving to the right
• Shows both low speed & high speed damping control
• Progressive (purple), linear (red) & digressive (white)
KONI Sport
• KONI Rebound adjusted to min. & max. settings
• Degressive curve shape for low speed control &
high speed forgiveness
• Adjustment has effect from extreme low speed
across complete speed range
Tokico Illumina
• Adjusted to positions 1-5
• Somewhat degressive curve on high settings
• Most adjustment effect in mid-speed, some at high
speed and very little at low speed
• Bump did not change on this valving
KONI Sport vs. Tokico Illumina
• KONI adjustment has more effect across wider
range of piston speeds
• KONI has more low speed, less high speed
rebound damping
• KONI has more medium to high speed bump
Bilstein
• Not adjustable
• Degressive curve
• Not much extreme low speed damping
KONI Sport vs. Bilstein
• Bilstein not adjustable
• Bilstein valving similar to KONI at soft setting
• Bilstein has higher low speed bump risking ride
harshness, KONI joins at mid & high speed
KYB AGX
• Adjusted to positions 1-4
• Somewhat degressive curve on rebound,
bump is linear
• Only low to mid range rebound is really effected
much by adjustment, rest of rebound and all bump
has nearly no change
KONI Sport vs. KYB AGX
•
•
AGX adjustment range is very narrow
AGX high speed bump damping more harsh
