Front: adj. -1.0"-2.5" / Rear: adj. 1.0"-2.0". Blueprinted as coil overs (not just a modified shock body), the H&R units are hand made in Germany by H&R Spezialfedern, under ISO 8001 Quality Assurance Standards. H&R Coil Overs are designed specifically for the 318ti chassis with the added feature of ride-height adjustable rear suspension - something not found on many other 318ti coil over kits. Special H&R Coil-Over Wrenches are included in this price.
