hey ive just lowered my 172 cup with apex 40 mm springs, when fitting the springs i tightened the top nut as much as i cud without the shaft of the shock turning, refitted the shocks and put the top mounts on as tight as i cud ,today i lifted the bonnet to find that there is now a gap between the bottom of the top mounts and where they should lie flush on the bodywork of over 1 cm . is this normal as i cant get them any tighter? i also have a lot of vibration coming through the steering wheel??can anyone help please, thanks
