Description
For the driver who demands the best from their vehicle, the Dinan Adjustable Coil-Over Suspension System offers unparalleled versatility and performance. Bred in the race lab and refined for the street, this suspension system ensures superior handling, reduced body roll, and enhanced traction, providing newfound confidence at higher speeds.
Dinan's design retains the superb factory electronic shocks but upgrades the springs to a more aggressive formula. Threaded collars allow for easy ride height adjustments, while the progressive rate rear springs are swapped for a more predictable linear rate spring design. The result is a sleek, lowered stance that enhances both handling and visual appeal. The progressive bump stops and additional components increase travel, enabling a front drop of up to two inches and a rear drop of up to 2-1/8 inches. However, for optimal ride quality, Dinan recommends a 1" drop in front and a 1-1/8" drop in the rear.
Features:
- Adjustable Ride Height: Threaded collars allow for easy and precise front and rear height adjustments.
- Lowering Capability:
- Up to 2" lowering in the front and 2-1/8" in the rear, with a recommended 1" front drop and 1-1/8" rear drop for optimal ride quality.
- Stiffer Springs: Spring rates are 20% stiffer in the front and 15% stiffer in the rear. Stock rear springs are progressive, whereas the Dinan springs are linear.
- Enhanced Stability: Substantial reduction in body roll, dive under braking, and squat under acceleration.
- Progressive Bump Stops: Dinan-spec progressive bump stops improve ride quality at lowered heights.
- Durable Components: Machined from 6061-T6 aluminum and black anodized for appearance and corrosion protection.
- Quiet Operation: Utilizes stock upper spring mounts for quiet performance.
- Helper Springs: Utilized in the front and rear to maintain proper suspension operation under droop conditions and accommodate extensive travel of the stock shocks.
