I had some Koni SA struts thrown on the front of my car, but the front end seems to bounce a lot, specially at high speeds. I looked them over with the wheels on and the car jacked up pretty good, but I can't find an adjustment anywhere.

Also, what is the best adjustment for street, another another for drag use?

 

at the top of the tube below the collar is a window. you need to stick a small allen wrench or thick (straightened) round cotter pin in the holes to sweep left or right.

the koni singles have about 10 sweeps from full soft to full hard. For good handling they need to be around 6-8 hard (+). for drag make em full soft (-)

the bouncy feeling might mean the shocks are damaged. check for oil coating the tube. konis can be rebuilt.
maybe the springs are too soft or worn out

 

Thanks for replying, can I adjsut them with the car on the ground and the wheels on?

 

no lift and pull wheel

 

You will need a 3mm Allen wrench (key). If you don't have a long one do yourself a favor and get one.
