***NOW SOLD PLEASE LOCK***
Set of Eibach lowering springs - these will drop your Z 30mm. Can be used with OEM shocks (I did). I used these with standard Rays, with AND without spacers (30mm rear, 35 mm front) with no issues.
Bought earlier this year but barely done a couple hundred miles, gone back to standard now as my new front bumper is too low/long for a lowered car.
£150 plus postage, or collection / delivery within reason around Chesterfield, Derbyshire. Am up in Durham on Saturday collecting my seats so if you're up there or en-route we can work something out...
