For the enthusiast that needs adjustable ride height, the Dinan Coil-Over Suspension is for you. Dinan’s provides Beehive shaped front springs and low profile camber plates with progressive bump stops that allow the car to be lowered up to one inch and still maintain stock suspension travel. Dinan Quiet Design Camber Plates make it the quietest coil-over suspension on the market. Suspension packers are included to fine-tune handling and comfort by changing the clearance of the progressive bump-stops, something no respectable racecar is without. Camber is easy to adjust due to the slotted front mounts and is adjustable between -1.2 to -3.2 degrees. Strut mounts are machined from 6061-T6 aluminum and are designed with heavy-duty rubber and barrel-shaped Delran internal components for superior performance and quiet operation, compared to noisy spherical bearing style mounts. All components are compatible with 2.50″ I.D. racing springs for convenient adjustment.
