i bought koni suspension used one. struts and spring the model no is 8041 1153SPORT and they have gmax springs on them which are G-MAX 30 HO....

the guy i bought them offf told me they were height adjsutable but i cant seem to adjsut the height cos there aint no coil sleeve or anything. There is a perch were the spring sits on and another slot in the strut were the perch may slide into about 1.5 m lower down the strut.
also are these height and dampning adjustable. if so how can they be adjusted.
thanks

 

Take the clip holding the lower perch off and move it down

 

currently the springs is sitting on the middle groove. there is one grove above and one below. i have 40 mm lowered springs on these so do i need to move the perch to the lower grove. if so how do i do it please. there is no thing which will hold the perch on the lower grove. there is a sort of ring on the current grove do i need to move that. thanks

 

The middle is stock height on stock shocks. Most people use the middle perch because if you go lower you can bottom out the shock which is bad for the shock and your car.

 

thanks. so if i leave it on the middle perch and use 40mm lowered springs will this lower the car 40m or do i have to move it down to the last perch to lower it. thanks
