I got an ef xr8 a couple weeks ago and just noticed it has red koni adjustable shocks in it. How do i adjust them? and it has blue springs what brand would they be?

From memory with Koni reds, the shock has to be taken out, compressed then the piston turned. This will adjust it to the next hardness level up or down.

Blue would probably be Lovells.

What he said ^^^^^^^^^^^.....when the shockie is completely compressed, turn the piston rod ( thats the chrome rod bit ), clockwise to make it stiffer, or anti-clockwise to soften it.
When doing this, there should be a clicking feel to it.
After this has been done compress & decompress ( up & down or in & out if you like) to feel the difference and to get the oil flowing in the right place, keep upright while doing this, and when assembling the spring & top back on, and when installing back in the car.

Ok pretty easy then, cheers for the replies.

The reds usually have 2.5 turns of adjustment, that's 2.5 times 360degrees. When fitted new to a std car they are ready to go on as they are out of the box, they will be at the lowest setting. If h/d coils are fitted they should be adjusted one turn (360deg). The adjustment affects the rebound damping, which is important to be able to do when different spring rates are used, or enhanced handling is desired. Changes to the spring rate do not necessitate a change in compression valving, so it doesn't matter that the compression is not readily adjustable (though it can also be changed on a koni).

As they get older they develop less damping forces (like any shock), and this can be compensated for by adjusting them. When people do this the shocks can last for a very long time. I think the rebound damping tends to reduce over time more so than the compression damping because the piston wears against the inner tube and allows some oil to bypass the rebound valving. So from a wear perspective it's also more important for the rebound to be adjustable.
